There are several basic types of bits:
Slotted. classic, universal purpose, for screw heads or screws, their cut is suitable for a flat screwdriver, they may differ in tip width and depth of cut.
Items of standard size are most commonly used.
Cross-type. composed of four ribs.
Hexagonal. used for screws with an internal hexagon.
Bits for screws and nuts. suitable for fasteners with a high load-bearing capacity outside hexagon.
Star-shaped. most often chosen for automotive applications.
Classification of bits by material and coating
The properties of the material from which the hardware is made, as well as the coating, determine its strength and resistance to wear. The following alloys are considered to be the best for the manufacture of electric screwdriver bits:
Phillips type bits (Cr-V)
The most common is chromium-vanadium alloy.
Metal fasteners are also made of other metals, such as high-speed steel (from R7 to R12). But such cheaper alloys are inferior in their performance indicators (strength, wear resistance) to the reviewed variants.
The nozzle on the electric screwdriver for self-tapping screws, bolts and other varieties of fasteners can be coated with these materials:
Zubr “EXPERT” diamond-coated bits
The coating increases the resistance of the working tips to corrosion processes, improves their wear resistance and durability. Titanium coating emphasizes the quality of the product. It has a yellow hue.
How to choose the right bit for the job
The market for bits suitable for electric screwdrivers is filled with products of varying quality and brands. For this reason, the question is relevant: what manufacturers’ products are better to buy as a set, and which individually? the right choice determines not only the bit wearing time, but also influences the working life of the power tool and the quality of the work.
Tips for buying piece parts
For piece-by-piece purchase, experts recommend Whirl Power (WP) brand products. It can be easily distinguished from its counterparts by the presence of a green brand sticker. This company’s products have earned great popularity and credibility due to their good magnetic properties, as well as considerable hardness, which increases service life through slow wear. Attachments fit in the chuck with no problem and do not fall out when the power tool is tilted down. Magnetic bits hold metal fasteners well. allowing convenient work in hard-to-reach places.
The following bit sizes from Whirl Power are popular for practical use:
The 150mm long bits are also widely used.
Standard WP2 models are used for work with most varieties of fasteners. If you need to perform operations with decorative modifications of self-tapping screws, then use tips for the electric screwdriver WP1. Working parts are equipped with notches that increase their resistance to wear.
Customer reviews of Whirl Power products are positive. Businesses from various fields purchase them in large bulk.
Practically as popular as Whirl Power among customers are products of Bosch, which traditionally supplies the market with high quality power tools. The quality of screwdriver bits from this brand is also emphasized by their high price. Especially popular are products coated with titanium, which are marked in yellow. Main material is chrome vanadium, tungsten molybdenum or chromium molybdenum alloys. In addition to titanium, tungsten carbide, diamond or nickel are used as protective coatings on the workpieces.
The titanium coating significantly increases the cost of the products. Because of this, the hardware from Bosch is two or more times more expensive than its Whirl Power counterparts. In such cases, the financial factor is the main focus of the bit selection.
The cheaper competitors to Bosch are the bits from DeWALT. Their distinctive feature is a high degree of impact resistance. They can be used regularly over a long period of time. To use in the home, the metalware from Magna is also suitable. They will last a long time if used with care.

Hints and tips for buying sets: what to look for when buying
To know which bit to choose for an electric screwdriver, you need to remember a few general rules.
Material of production
You can judge by the material how strong and durable the bits are:
- Steel R-7, R-12. Applicable for standard bits.
- Chrome vanadium coating. Provides corrosion protection.
- Titanium nitride coating. Gives them a high degree of toughness.
- Titanium and tungsten plating. Together with the diamond coating, these bits are able to improve the grip on the slotted section. Ideal for intensive use.
The most popular machining of bits are milling and forging. Forged bits retain a homogeneous structure that does not deteriorate over time. When a bit is milled, it is given a specific shape. The top layer is removed. That is why tools obtained by forging are considered to be the toughest. The bit is also tough if it is hardened.
Some manufacturers, like Bocsh, have their bits heat-treated, which makes them better able to handle tough jobs. There are bits with profiles. They are needed to loosen hard joints and for work in hard-to-reach places.
Carbide bits. not always a good thing. They are roughly divided into hard and soft. In the first case, bits are more durable, but brittle. They can be used in screwdrivers with low torques. Soft bits break quicker, but are good for hard fasteners. The average hardness value for the bit is 58-60 HRC.
Almost all bits have this kind of feature. For example, if the working side is magnetized, it works better in the slot. But sometimes a magnet can be a nuisance. Chips may form when working with metal. It is attracted to the bit, which shortens the life of the bit.
For an electric screwdriver with an impact, you might consider torsion bits. Compared with standard nozzles, it is less subject to wear and is able to withstand high loads.

What to consider when selecting bits
Sets of industrial bits are available as separate items in retail outlets, but the standard bits kits that come with a screwdriver already contain sets of various bit formats.
The quality of such products is not always at an adequate level and in any case it is necessary to look for a replacement. The search for a suitable accessory material for power tools must consider a tight fit and a secure connection between the bit and the screw.
Neglect of such requirements will lead in the future, when working with power tools, to permanent disruption of the bit and its screwing in the screw.
Representatives of this price segment are made by well-known brands with an excellent reputation in the manufacture of construction equipment. Today, these are some of the most durable and popular models available on the market.
