Maintenance Tools: Requirements, types and Tips for choosing

Locker tool – a complex set of devices, the task of which to facilitate the work on the processing of metal and some other repair processes. The range of application of these devices is very wide, and therefore the variety of them is great. It is enough to bring examples of metal operations that cannot be made without the appropriate toolkit to understand the importance and specifics of its application: drilling, bending, cutting the threads, cutting, cutting.


Each plumbing tool, depending on the area of ​​its application, distinguishes their characteristic features.

First of all, this is the material from which it is manufactured. Since the scope, for example, the cutting tool – metal, then the hardness of the alloys from which it is manufactured. High strength requirements and installation tools. Made from special steel and sometimes with special hardening conditions, tools have a wide range of use for a wide variety of works.

Inventory should be quite comfortable for locksmith. Working with solid materials requires efforts that in case of low-quality or uncomfortable handles, it may cause serious injury.


The use of the tool dictates and requirements for its state. Separately, it should be focused on the one that is designed to work with the objects under electrical voltage. For example, installation of electrical wiring. Here only ergonomics can not do.

Special tool with insulating handles should not be applied to such or similar works. Unlike other mounting devices, it has less durable articulations and can get significant damage if it is not applied by appointment. Especially with such works, insulating handles suffer, not intended for significant loads. In turn, a reinforced tool that does not have electrical insulation – the consequences may be deposited for electrical installation work.

The most important requirement when working with a locksmith inventory are safety measures. GOST clearly regulates its application.

The main types and their appointment

The classification of the entire diversity of the plumbing tool is based on the diversity of its use. Even if you bring a simple list in alphabetical order, it will take a significant amount, so we still give the generally accepted classification of the professional instrument.

Manual shock

It is a different kind of plumbing hammers and sledgehammers, including blacksmith. Apply them for cutting and flexing metal, punch holes in it.

Kerners needed for marking can be attributed to the drum group. The cutting of the metal is impossible without a chisel – it is also a shock layer tool. Special chisel for applying recesses in metal – Crantsmeysel, in fact, as well as the usual, but with a narrow cutting surface that allows you to pierce the groove or recess. Apply it without a hammer, as in the case of a chisel, will not work. Thus, the hammer is another standard tool in the set.


A separate group shape clamping or hinged-glass plug-in tools: pliers, passage, tongs, ticks. Stationary vice – also clamping tool. Hold a metal blank when it is processed is impossible, and sometimes dangerous. It was for such an operation that the instruments of this group were invented.

For cutting thread

Metal parts are already tested with threaded connections for several centuries. Special tools were also developed for thread cutting. The outer thread is cut by a radiator, clamped into a plaster, connected to the gate, the rotation of which is cut into the thread.

The tap for cutting the inner thread is also held by a special device. Both the other tools have grooves for collecting chips. Made them of high quality tool steel.

For mechanical processing

Mechanical processing of metal is carried out using files, and fine refinement or processing of small parts using supules. With the help of these devices, you can saw metal.

For metal cutting

For cutting metal parts applied hacks. This tool can cut a metal sheet, bar, pipe, corner. Metal sheet can be cut using special scissors, manual or stationary, one of the cutting surfaces of which is fixed motionless. Shabab allows you to remove a thin layer from the surface of the products, this operation is necessary to create high-quality metal parts compounds.

For drilling

Metal holes are obtained by drilling. For this use:

  • Different diameter of drill from doped steel;

  • For better hole processing, sweeps are used;

  • To make a bolted or riveting connection, chamfer are selected – it allows you to drown a bolt head or rivet flush;

  • Zenkovka is used to implement this operation;

  • If it is necessary to improve the quality of the finished hole, for example, to fit it under a slightly larger diameter or align the hole drilled under some angle, zenker is applied.

Plumbing and mounted

A special group is formed by the tools necessary for assembly, so-called fitter assembly or fitting and assembly tools. For threaded connections (bolt – nut) Apply wrenches. The horned keys are widespread, cape, end, adjustable (can be adjusted depending on the size of the head of the bolt or nut), ratchet and hinged.

A variety of wrenches involves the use of them in various conditions. In some cases, it is necessary to dose the effort when tightening the threaded connection, dynamometric keys were invented for this. For screws or screws (self-tapping), screwdrivers with straight or cruciform spitz.

Measuring tools

Metal processing is not possible without accurate measuring instruments. The easiest of them is a ruler. However, its length is always limited, and too long to use it is inconvenient. In order to avoid such inconvenience, a flexible line was invented – Roulette.

For accurate measurements, stanciturkuli, calorieglubiodemers and calipers. No less important of various kinds of pattern, probe and calibration bars and stoves. These tools allow you to determine the microscopic values ​​of different kinds of gaps with their subsequent adjustment. Various levels and tomitics are also used to measure adjustments. In the work with electrical equipment requires indicator devices.

In addition to the above classification, there is a division of plumbing tools into household and professional. It is quite simple to distinguish them, first of all, by price. The first is usually more expensive, however, the quality of it is significantly higher.

Tips for choosing

The selection of a plumbing tool is determined by its application. First of all, it is necessary to represent the difference between the so-called domestic and professional instrument.

Buying an expensive plumbing tool, if the use of it is assumed for irregular household repair and installation work, may be unnecessarily costly. Of course, in any house there should be a standard set of elementary tools: hammer, passage, adjustable wrench or even two, screwdriver flat and cross. They can be useful for minor repairs – for example, the adjusting screw of the cabinet door has unscrewed, the crane-shot and other household breakdowns spoiled.

But for serious professional activities, such a toolkit cannot be used in no case. For professional tools, special instrumental steel is being developed, which makes them more expensive, but also increases the resistance to wear. In addition, the professional tool is distinguished by high quality handles and not only in relation to the material from which they are made, but also in relation to the form. Such an ergonomic tool does not slip out of the hand, the handle in no way scrolls, it is convenient and does not rub the hand with long use with a significant effort.

When buying a tool for home should not be deducted too low. In this case, soon you will have to spend the tool again.

It may fail at the first use. However, too expensive is hardly worth buying. Costs, as they say, do not pay off if the acquisition will lie for months without.
