Requirements for hand tools and accessories. Metal cutting tool. Types and characteristics What is included in the tools

Hi all! Today I will tell you what tools may be needed for absolutely anyone repair of any complexity.

The most important tool, without which not one repair can do, is perforator. This universal tool combines the functions of such tools as a drill, a jackhammer, a mortar mixer, a screwdriver. In order for the puncher to perform as best as possible more features, for it you need to purchase the following components:

- drill for perforator with a diameter of 6 mm, 8 mm, 10 mm (the most commonly used dowels have a diameter of 6 mm, it is better to use anchors with a diameter of 8-10 mm);

- chuck with adapter(because you can’t just insert drills for metal into a puncher, you will need a cartridge);

- mortar mixer, which is inserted into the cartridge;

- spade and spatula for the destruction of concrete, is inserted directly into the hammer.

The second most important repair tool is screwdriver. A screwdriver, unlike a hammer drill, performs two functions: the first is tighten and unscrew self-tapping screws, dowels, anchors, bolts and the second is drilling holes in metal. As for a hammer drill, some accessories should be purchased for a screwdriver:

-bit set for tightening various self-tapping screws;

- metal drill set different diameter;

- bit for tightening anchors and bolts.

If you need to cut a metal corner, channel, pipe or plastic panel to the desired length, then without Bulgarians you can't do it. For a grinder, you should buy three types of discs: cutting for metal, diamond and grinding. Using cutting disc for metal, it will be possible to cut any hardware and plastic. Using diamond disc, it will be possible to cut products made of concrete, asbestos cement and ceramics. And finally grinding disc You can grind various metal products.

Without building level Not a single repair is needed. If you need to level a wall or floor, then you can't do without a level. Levels come in various lengths: from 20 cm to 2.5 meters. For the installation of windows and doors, a 40-centimeter level is suitable, for leveling walls, ceilings and floors, a 2-meter level is suitable. The most popular level is bubble spirit level. Thanks to alcohol, the level can be used at sub-zero temperatures. For repairs, you should purchase a building level that combines horizontal, vertical and rotary levels.

Roulette

As the proverb says - "Measure seven times and cut once" and this will help us roulette. Tape measure vary in length measuring tape, and their length varies from 1 meter to 10 meters. The most optimal for repairs will be a tape measure 7 meters long.

For sawing boards, bars, fiberboard or chipboard, you will need hacksaw. In repair, hacksaws with large teeth and small teeth. A hacksaw with large teeth can easily handle thick boards and bars, while a hacksaw with a small tooth is suitable for plywood, fiberboard, chipboard and plastic.

- the most indispensable tool used everywhere. The variety of hammers on the market right now is off the charts. To repair you will need the simplest hammer with wooden or metal handle, square section, one side of which flat, and the other beveled to the corner.

- these are pliers and wire cutters in "one person". They can bite the wire, pull out a nail or bend some part. Pliers must be with insulating plastic on the handles, to perform electrical work.

For repairs, it is best to purchase combination wrench set with sizes from 6 mm to 22 mm.

Designed for plumbing work.

designed to determine right angle. It is very important that the divisions and numbers are carved on the corner, and not drawn with paint. Otherwise, in the future, all numbers and divisions will be erased.

Designed for removing nails from wooden elements and for dismantling old wooden structures.

Spatulas

If during the repair you need to cover up cracks with putty, level any surface, cover up mounting foam, then you will be helped spatulas. For repairs, you will need three types of spatulas: narrow, wide and serrated. Narrow spatula with a width of 60-80 mm is intended for applying putty on a wide spatula and for puttying in narrow places. Wide spatula 200-400 mm wide is intended for filling walls, slopes, etc. intended for application adhesive solution on the surface of tiles or decorative stone.

Hand tool sets - a compact tool for home master or a motorist. Professionals do not neglect them: electricians, plumbers, employees of service centers.

Types

The set consists of a tool box and its filling. Sockets, bits, turning tools and spanners, which are part of a set, are classified as its parts.

The more parts the kit contains, the more versatile it is. The largest sets consist of 500 or more items.

Boxes are made of metal, plastic or other materials. The sizes vary from small cases to overall racks on wheels. A common form is a tool case or briefcase.

The tool is grouped into thematic sets of three types:

1. Universal, automotive or special kit. This is the most common gradation, which is taken as a basis by most manufacturers.
2. For motorists, small household needs and other serial works. These are home kits.
3. A series of tools of the same type with different parameters. More often, such kits are focused on professional use. Nozzles for power tools can also be grouped.

Household series are different from professional ones. Home kits most often include a hammer, a pair of pliers, and a few screwdrivers. In automotive - devices for minor repairs cars.

The number of set units is limited to the elements that are needed to perform most household tasks.

Professional models are made from alloy steel. Kits sometimes include batteries, multimeters, and handy fasteners in common sizes.

Types of tool kits

To describe the species, the standard gradation adopted by large manufacturers is used: universal, auto and special tools.

The universal locksmith and assembly kit contains sets of individual tools or an assembly of different elements:

• screwdrivers and bits;
• end heads;
• keys;
• extension cords;
• collar;
• ratchet;
• head holders.

The locksmith's tool is suitable for car repairs, minor household repairs and for household work.

A set of tools for the car. The series are designed for repair and maintenance work. Divided into special kits:

• for car services;
• for Russian cars;
• for motorists;
• for trucks.

Sets of highly specialized tools for installation work. Most often used in the field of telephony and electricians.

Kits:

• drum beat;
• dielectric screwdrivers;
• dies and taps.

The electric kit also belongs to the special kits. It includes different types wire cutters, dielectric screwdrivers and special tools for mounting and laying cable lines and installing electrical appliances.

There are also kits for carpentry, which are sets of chisels, cutters or engravers for carving.

Specifications of tool sets

A hand tool is characterized by the type of work for which it is intended, and the materials from which it is made. Despite the dissimilarity of these parameters, they determine the functionality and service life of the kit.

• Automotive - are selected for standard household car malfunctions and preventive maintenance.

Such a kit is enough to tighten the knots, solve minor problems with electrical wiring, flaring, and replacing small parts.

There are separate kits for specific brands of cars, more often we are talking about American cars, in which the fasteners have connectors of their own design. Kits for domestic cars are suitable for all models of GAZ, UAZ, Volga or Lada.

• Mounting - Suitable for electrical and plumbing work. Sometimes supplemented with a small electric, pneumatic or cordless tool.

Most of these sets are focused on household needs, since professional skills often require an individual selection of certain types of tools from different manufacturers.

• Locksmiths - sets for processing wood and chip materials. More common are universal kits for installing doors and locks.

Locksmith and installation characteristics are often combined in universal kits.

High-alloy steel often characterizes professional tools designed for long-term operation and constant loads.

• Household models are made from metal alloys. There are also frankly disposable things in which the metal parts bend and break at the first use.
• Chrome plated metal elements looks aesthetically pleasing, but more often hides metal that is not resistant to corrosion. One scratch on the surface and an oversight during storage is enough to rust the tool.

Also on performance characteristics the material from which the handle is made. In professional models, rubber coating is more common. They almost never have plastic handles.

The total number of tool units in the universal set varies within the following limits:

• Number of bits: 4‒142 pieces. The minimum set includes common slot shapes. The maximum set contains slots of different diameters and is complemented by rare variations of shapes.
• Number of drills: 1‒33 pieces. The fewer drills, the more likely they are for woodworking.
• Number of ratchet keys: 1‒5 pieces.
• Number of screwdrivers: 1-7 pieces. Models of different lengths, slot shapes and functionality.
• Number of hammers: most kits contain one hammer.
• Number of pliers: 1-2 pieces. More often there is a combination of pliers and wire cutters.

In auto and special kits, most of the elements may be missing.

The maximum equipment is provided in household models and options for service.

The functions of the kits correspond to their names.

• - used for domestic or professional needs. More often these are the maximum sets, consisting of a large number of elements for all occasions.
• - serve as a basic tool for preventive maintenance and minor repairs of cars and auxiliary - when changing wheels, installing alarms and car radios.
• - special sets are not universal, they are selected strictly according to the type of application, in accordance with which they are completed. Responsible fine work is often impossible to carry out without the use of this type of tool.

Universal and Autodial are partially interchangeable.

A tool that is present in special kits is extremely rare in other kits.

Kit in toolbox

The equipment is based on a combination of individual types of tools or elements of the same type, but with different parameters. The universal kits are based on wrenches, screwdrivers and bits. In automotive - end heads.

Most kits include, but are generally not limited to, one- or two-sided solid wrenches.

Keys included in the kit:

• Horn- work profile U shape or with an open mouth. It is always located at an angle to the handle. The key captures fasteners from two or three sides.
• Cap or ring- to cover fasteners from all sides. The cap profile has six and twelve faces. The larger, the smaller the angle required to work.
• Combined- from one end they have a horn profile, and from the other a cap profile.
• end- for car repairs. In composite models, nozzles of different sizes are attached to one handle.
• Ratchet or ratchet- the key does not need to be thrown when unscrewing the fasteners.
• Adjustable- The distance between the jaws is adjustable. One wrench is used to work with fasteners of different sizes.

In professional sets, there are keys with a reverse mechanism. This is a switch for changing the direction of twisting with one hand.

Sockets are an alternative to open end wrenches or box wrenches. Mainly used by car owners and service companies. The dimension is metric or inch.

Socket sets vary in the number of parts they contain. It can be a small set of 13 heads or a complete set - 573 pieces.

Sets are completed according to the form parameters:

• Hexagonal or dodecagonal profile . Equipment is most often combined with different amount faces. There is also a modified hex profile where the force is applied closer to the middle section.
• Landing square gauge . The top of the head is equipped with a square hole to mate with the drive. This hole is called the "landing square". The caliber is indicated in inches.
• Head length - standard or extended. Elongated heads are used with parts on high studs or with elongated threads.

Socket sets sometimes include working elements: knobs, reinforced universal joints, ratchets, extension cords.

For work in confined spaces, sets with ratchet mechanism and frequent step are used. Options with several adapters and extensions are preferred, which help to get into hard-to-reach places.

Used in car kits to fix spark plug holes, bolts or nuts, when cutting pipe threads. They are available in inch and metric sizes. It is important to maintain a triangular thread profile on the last threads.

• Cone models have a trapezoidal stop and are used for cutting without restrictions.
• Solid models are used for carving hard metal.
• Split or sliding dies are used to create deep carvings.

Split, sliding and solid versions are the most common and versatile, they can be used instead of a cone valve. The kits include metal handles.

An individual or universal tool kit often contains a long Phillips and flathead screwdriver, as well as a short combination that can reach the screw heads in a limited space.

• For permanent work with electricity, sets of insulated screwdrivers are produced to protect against electric shocks.
• In professional kits, there are tester screwdrivers and battery models with bit sets and reverse.

Screwdrivers with interchangeable or magnetic tips are available even in household kits.

Drill bits differ in the type of application - for metal, tile, concrete or wood. Visually, the difference can be seen in the frequency of the thread and the shape of the limit switch. In universal kits, wood drills are more common.

According to the type of metal, they are divided into cobalt and titanium-coated models:

• Cobalt drills are produced in 2 grades with different percentages of metal. Class M35 contains 5% cobalt, while M42 contains 8%. This option is more common in professional kits.
• Titanium drills should be used at low temperature with reduced friction to prolong life.

The kits contain the following variations of drills:

• Screw or twist drill. Used for working with wood or soft materials - the most common option.
• Flat drill in the form of a pen or pen. On a long stem, with a cutting edge in the form of a spatula or a narrowed trapezoidal protrusion. It is used to create wide round holes in wood, tie-in locks.
• For one-sided cutting. It has a reference plane, the edges for cutting are on one side of the center of the drill.
• For deep drilling. Long drill with two screw channels. Supplemented with coolant. Channels are provided for it inside the drill or rear tubes.
• Hollow drill or crown. Drills a thin ring of a given diameter.

Cobalt is a more reliable option, these drills are sharpened many times during operation, they retain their sharpness longer, unlike titanium.

Additional tools that come with most kits are pliers and hammers. Pliers are sometimes included in the basis of special sets.

Pliers - in sets there are adjustable and monolithic models.

Adjustable pliers allow you to spread the jaws to different widths, while monolithic options or pliers are installed in place and block the part of the size that can fit into their groove.

Some pliers, although designed for common use, have marks that are suitable for bending household electrical wires.

They are able to bend the wire into a tight curl to effectively wrap it around the screw and provide an adequate electrical connection.

Hammers - they are completed with universal and carpentry sets. More often we are talking about a small hammer, sometimes with a bifurcation at the end, imitating a pry bar, or sharpening in the form of a pick.

Such a hammer is used for its intended purpose and for dismantling. The larger the metal part of the tool, the more powerful it is. The length of the handle also enhances the punching power.

Hammers with small handles for maximum force must be held by the very edge. For delicate work - hammering small nails, fastening wires - the force of impact is softened by a shortened handle.

The basic accessories include interchangeable nozzles of various types.

In universal kits, chrome-vanadium and chrome-molybdenum bit models are common.

The kits contain nozzles with a different shape of the slot. The minimum set includes the main options:

• Cross slot - Phillips. More often there are options marked PH 3. They are suitable for most types of self-tapping screws, including the option with a 3.5 mm head.
• Cruciform with ribs - Pozidrive. More rigid fixation of self-tapping screws.
• Flat or straight slot - Slot. The base size is 5 mm.
• Hexagon - Torx. Slots of internal or external type. If there is only one option, then in most cases it will be internal Torx.

Hexagons are also found in separate independent sets. In this case, instead of ribs for insertion into a screwdriver and fasteners for a screwdriver, they are equipped with small handles bent at an angle of 45 degrees.

An additional titanium coating gives the bits strength, while the carbide and tungsten option provides anti-corrosion properties. Such coatings are found in professional kits.

Air tools are more efficient than electric models, delivering full torque at the touch of a button. Therefore, for him there are own sets of nozzles.

A good set of pneumatic attachments includes an impact wrench, a socket wrench and a universal joint.

For pneumatic, there are separate kits with interchangeable nozzles of different diameters. They are adapted to materials of varying degrees of density and size of fractional particles.

The basic features depend on the type of set you prefer. In each case, they are individual and may be present in minor details:

• Comfortable handle for extended use. The presence of threads, rubberized pads, ergonomic design do not play a role in rare and short-term use, but for long-term or permanent work, these are defining features.
• The versatility of butt joints, the possibility of replacing with similar parts from other manufacturers, the density of threaded connections are features that determine the convenience of using sets in work.

Most kits meet these requirements, but if there is an exception, it is worth re-evaluating the prospects for purchase.

• Anti-corrosion protective coating - significantly extends tool life. Models without it leave marks on their hands and finishing materials shortly after the start of operation.

Set features are not separated by type, as their use is determined by work needs. But universal kits medium sizes are more often produced in maximum quality.

The advantages of a hand tool correspond to its types:

• Automotive the kits are suitable for most routine preventive maintenance and eliminate the need to contact a car service with minor breakdowns, they are indispensable on the road.
• Universal The series are convenient with an abundance of shapes, sizes and functional elements. The main advantage is the interchangeability of individual components.
• Special The kits are designed for professional use. As a rule, do not contain unnecessary elements. Each component is applicable to work.

The basic advantage of any set over a separate, albeit high-quality, tool is the possibility of flexible selection for a specific task without the need for visits hardware store if something is missing.

The kit includes basic parts and nozzles at hand.

Disadvantages are also divided according to the type of set:

• Automotive variations contain elements only for simple knots. Standard parts will not help to fix even a small breakdown of a specific vehicle assembly on their own.
• Universal series contain many unnecessary components that will never come in handy. The quality of such sets is rarely found at a decent level.
• Special variations are practically inapplicable for everyday needs. If purchased without a professional need, they often do not pay off.

Critical shortcomings in different types there are no sets. They appear only due to the reduced quality of the tool.

How to choose a set of tools

It is worth choosing tool kits that correspond to the work ahead.

The base consists of only five items:

• wrench;
• flat screwdriver;
• crosshead screwdriver;
• hammer;
• pliers.

These five tools allow you to perform most everyday tasks.

Basic principles for choosing the best tool:

• Metal. When choosing large sets, pay attention to the material of manufacture.

High-alloy steel as the base metal is reliable, but if hard operation is not planned and increased loads, the choice of this metal is sometimes not justified.

• Number of interchangeable nozzles . It is believed that the more of them, the more convenient, but this is not always the case. If the nozzles that are more often needed for work fail, the extensive kit becomes useless.

Therefore, models are preferred in which the most common sizes and shapes of nozzles are duplicated.

• Case, pencil case or box. If frequent carrying of the kit is required, then a case or box with a central handle is preferable. They contain a large number of elements, are convenient and mobile. For small sets, a pencil case is enough.
• Universal or individual? The choice is based on the upcoming tasks.

For episodic disposable work, universal kits are more convenient when you don’t have to think about the availability of the necessary small things. For permanent work, individual sets are selected.

The pursuit of quantity is often not justified. Sets bribe with false exuberance. Large sets of hundreds of items may include a tool that will never be used.

Low quality is often hidden behind the vast size of the collection.

Hand tool maintenance is subject to a set of operating rules:

• Before first use or storage, it is recommended to lubricate moving parts and components.
• For pneumatic nozzles, only oil is used for sewing machines or pneumatic tool.
• Kerosene is used to clean working parts from soot elements.
• After washing, the instrument should be wiped dry.
• It is unacceptable to use gasoline and alcohol-containing liquids for flushing.
• Avoid getting flushing liquids into working mechanisms.

In the event of a malfunction, stop using the tool and contact an authorized service center.

Security measures:

• Before work, you need to make sure that the tool has no mechanical damage.
• Make sure that clothing or hairstyle does not come into contact with moving mechanisms and components.
• Safety goggles are used when drilling or drilling.
• The tool may only be used for its intended purpose.
• Exploitation by people under the influence of alcohol or drugs is unacceptable.

With pneumatic tools, only impact models of end heads are used. The use of nozzles for hand tools is unacceptable.

Kits should be stored clean, lubricated and dry. Use the standard cases, pencil cases or boxes that come with the kit.

It is advisable to carry out preventive anti-corrosion treatment and lubricate the elements before each use.

Storage in rooms with high humidity is unacceptable.

Hand tools in most cases are covered by a standard warranty, which varies in the range of 1-3 years. Warranty service does not apply to cases of incorrect operation and mechanical damage to the tool.

Repair or replacement is carried out only if there are factory defects confirmed by the manufacturer. Also be sure to keep full set documents: warranty card signed and stamped by the seller, sales and cash receipts.

Some manufacturers claim a lifetime warranty on tool kits.

It is worth considering the nuances of this type of guarantee. Repairs and maintenance are carried out under the same conditions as under the standard terms, but often include a number of additional restrictions:

• The product is considered to be under warranty for a maximum of one year if it is a product with electrical or electronic components.
• The lifetime warranty does not apply to products that have been misused, altered or repaired without the participation of a service center.
• The warranty does not cover the repair and replacement of consumable items - knife blades, glue sticks, drills, etc.

Defective products that meet the warranty conditions will be repaired or replaced by the manufacturer at his own expense.

The manufacturer undertakes to replace a power tool that fails, regardless of the cause of the failure.

As a rule, an additional request is indicated not to try to return the broken tool to the store, but instead use the hotline.

Most manufacturers that provide this type of warranty state that they will not require proof of purchase.

In the case of universal kits, even wrenches, ratchets and drive accessories are included for replacement.

This full lifetime warranty excludes all incidental or consequential damages to the purchaser, except to the extent permitted by local law.

In ready-made sets, handles break more often and sets of nozzles become unusable due to the weakness of the metal, excess load or mechanical damage.

The specifics of a hand tool is such that its self-repair is not practiced. Of course, you can straighten the slot at a time, weld the nozzle or attach a tire to a broken handle, but this will inevitably affect the functionality of the tool.

Wear and tear on consumables is normal. A broken drill, tap or drill is replaced with similar elements. If the functional part of the tool is not damaged, these parts are not subject to warranty replacement.

Ruler

The ruler is necessary in order to ensure straightness in preparatory work, and also it is used for quality control over the work that is being performed.

Used to select the parameters of the tools to be used. For example, a caliper is used to select a drill for drilling holes.

Video: instructions for choosing a caliper

Hand tool

Hand tools include: trowel, trowel, spatula, brushes, rollers, hammers and mallets, wrenches and gas wrenches, as a rule, graters and trowels, buckets, as well as screwdrivers.

Trowel, trowel and spatula needed for plastering or finishing works co mortars. With the help of these tools, solutions are supplied directly at the places of their application, and after that the surfaces are leveled.

The rule is intended for leveling surfaces, focusing on lighthouses. And thanks graters and semi-graters you can perform the final finishing of the plane to perfect evenness. Brushes and rollers used to apply paint or glue, such as wallpaper. You can also roll the wallpaper against the wall with rollers, as they perfectly squeeze the air out of the wallpaper.

Buckets of course, they are used to transfer or store liquid and bulk building materials. Hammers and mallets are intended for driving nails, as well as for straightening and finishing materials when they are installed in place.

Screwdrivers used for unscrewing or tightening screws, self-tapping screws. Also, these things are useful for repairing power tools.

Wrenches or gas wrenches can be useful for working with screeds of firing joints, for example, when installing pipelines for a hot water supply or heating system.

Equipment for cutting metal, which is required when performing various construction and repair work, in industry and in everyday life, can be very diverse. The classification of cutting tools is made mainly on the basis of what purpose certain types of tools perform.

The variety of cutting equipment allows you to use the most suitable for each specific purpose. The choice of tool depends on the characteristics of the work performed and the desired result, as well as on the characteristics of the metal being processed.

Design features of cutting tools

Classification of cutting tools can be done according to different criteria. The main one is the design of the equipment. Depending on the design, such types of equipment can be distinguished as:

• cutters;
• incisors;
• vertical drills;
• drill;
• counterbores;
• sweep;
• taps;
• dies;
• hacksaw blades;
• shavers;
• abrasive tool.

Each of these species has some characteristic structural features, which determine belonging to one or another type of cutting tool. So, single-edged tools are incisors. They provide the ability to process metal using a multidirectional feed movement.

Metal processing with milling cutters involves the implementation of rotational movements of the tool along a trajectory with a fixed radius. In this case, the direction of feed movement does not coincide with the direction of the tool axis.

Drills are axial type cutting equipment. They are used in cases where it is required to make a hole in the material being processed or to enlarge already finished holes. During processing, the drills make rotational movements, which, to obtain the desired result, are supplemented by feed movements. The axis of rotation and the direction of feed movement are the same.

Countersinks are also axial tools. They allow you to correct the shape and size of holes in the metal, in addition, they can be used to make the hole diameter larger. Reamers can also be used to process holes. This type of equipment is designed to remove roughness from the walls of holes. This process is called finishing. End and cylindrical sections are machined with such an axial tool as counterbores.

For the manufacture of external threads on cylindrical metal blanks, dies are used. You can cut threads in the inside of the holes with taps.

Knife blades are multi-blade tools. In shape, they are metal strips on which numerous teeth of the same height are made. They are used if you need to cut a piece of the workpiece or make grooves in it. Translational movements in this case are the main workers.

Cutters are used for sharpening teeth on various parts. For example, on gears, shafts, etc. Gears can also be machined with shavers. The action of these tools resembles scraping. As a result, the parts are finished.

The group of abrasive tools includes various devices and materials for finishing parts. It can be special powders, grains, bars, crystals and so on.

Types of processed surfaces

In addition to design features, the classification of metal cutting equipment can be performed according to other criteria. For example, depending on the type of surface for which the equipment is intended to be processed. According to this criterion, the following varieties can be distinguished:

1. Products used to work with bodies of revolution of flat and external shaped surfaces. This group of equipment includes cutters, abrasive wheels, cutters and similar tools.
2. Equipment for making holes. Drills, broaches, boring cutters, countersinks belong to this group.
3. Devices for cutting threads. Such products include rolling rollers, taps, dies.
4. Products that allow you to process parts whose main element is teeth, that is, splined shafts, sprockets and more. For this, shavers are used, grinding wheels, cutters, break-in cutters, disk cutters.

Not every person has enough financial resources to hire a team of workers, and even more so an expensive contractor who will do everything. necessary work. Therefore, when repairing an apartment, its owner has to do everything himself.
