What is a precision screwdriver

One of the most useful tools in the house is a screwdriver. Especially if it has precise shaped profiles and is suitable for delicate work, for example, for unwinding various devices, watches and household appliances. After all, you can replace a regular battery or disassemble the clock mechanism yourself.

Simple construction screwdrivers will not help in such cases. For this purpose, precision tools with special profiles should be used. In order to have such a screwdriver, you don’t have to be a technician at a service center. In this article we will talk about this type of tool.

Precision screwdriver: what does it mean?

A precision screwdriver is a special type of tool that is used when carrying out precision work with small fasteners or parts. The device has a particularly thin and precise tip, which is sharpened to best match the small fastener heads.

Types of instruments

Naturally, a screwdriver for high-precision work and manipulation must comply with certain GOST standards and operating conditions. According to the requirements, its tip and base are made of steel (chrome vanadium, which belongs to the carbon class) or alloy metal. The tip must be hardened, since small grooves wear out much faster, unlike large ones. Hardness and stability are important requirements for a precision screwdriver.

However, the main thing that is required from such screwdrivers is high precision of the devices. The tip must strictly correspond to the dimensions of any type of fastener. Only then can the parts be connected without damage. It is for this purpose that manufacturers produce entire sets, in which the number of tools ranges from 10 to 12 elements with different sizes and tip configurations. Accordingly, the more of them, the faster and more convenient the repair work or disassembly of devices will be.

Precision screwdrivers are used in several cases. As a rule, when dismantling or assembling devices, parts and small parts:

• home appliances;
• all kinds of gadgets;
• clock mechanisms;
• mobile technology;
• laptop computers;
• laptops;
• game consoles;
• cameras.

Any service center for repairing the above devices has similar screwdrivers. More precisely, a whole set of precision instruments - each device can use a different component, type and size of attachment. For example, a straight slot or in the form of an asterisk, etc. There are several types of devices for precision work:

• Phillips slot;
• tip with straight slot;
• in the form of an asterisk;
• hexagonal;
• special slots (special Spanner, Pozidriv, etc.).

Interesting! For comparison, the well-known company Apple uses exclusively special anti-vandal screws. Naturally, they can only be untwisted with a special precision tool with a tip in the shape of a five-pointed star. It's called Pentalobe.

What should a precision screwdriver be?

A precision screwdriver is usually sold as a set.It can contain six to eight instruments. The set includes three or four heads of different sizes, diameters and widths. There are also Torx or star head positions. They are needed for electrical devices.

If work is being done in confined areas where there is a risk of losing a small screw, screwdrivers should have magnetized shafts.

The demands on precision tools have become greater as technology has advanced to the point that some repair work has become possible at home. Selecting and searching for the required screwdriver has become easier.

Requirements for precision screwdrivers:

• steel tip (preferably made of a tool alloy);
• hardened tip;
• the housing must be equipped with a collet clamp;
• a ribbed or embossed handle made of aluminum alloy is desirable (prevents slipping when performing work);
• solid and durable elements;
• rotating end cap;
• a large selection of tips in sets (from 10 to 12);
• accuracy.

The Berg set is popular among consumers. It includes as many as 20 different attachments, and the cost of such a set does not exceed $15.
