Milwaukee Shockwave Impact Duty
Equipment from “Milwaukee” is considered eternal. Even if the screwdriver is not let go of your hands every day, the edges do not break off. The Milwaukee Shockwave Impact Duty series showed an amazing result in tests - 6088 screws with one bat!
There is no need to talk about a clear cut of the corners; it fits perfectly into the screw and does not damage the head. There are bits of different formats in a row. The downside, however, for model 1 is the price. You will have to pay $10 per piece. But a set of 30 cue balls with a holder will cost only $75, and this is a real saving!
DeWALT FlexTorq
And here is another American manufacturer, widely known among us. We cannot say that these are the best bits for a screwdriver, since in the test they showed a result of 2600 screws, but their price is 2 times lower.
DeVolt claims that these attachments have the most correct geometry, so they do not tear the spline. But what’s really convenient is rotating the torsion core by 15 degrees around its axis. This prevents the screw from stopping abruptly.
The complete set includes all varieties: 3 cross sizes Ph and Pz; Torx; flat slotted bits. Diameters: 25 and 57 millimeters.
Type of coating on the bat
Quality depends not only on the material, but also on its heat treatment. Hardened tools are much stronger and more durable.
Also, equipment can have additional coating to improve performance characteristics:
- Chrome vanadium. An inexpensive coating that protects against rust, but wears off quickly.
- Titanium. It is distinguished by its golden color. Provides corrosion protection and increases strength. Titanium nitride alloy coating also falls into this category.
- Diamond. The most durable and durable coating. Significantly increases the wear resistance of the base alloy. These bits are suitable for heavy loads.
Wiha MaxxTor
And here is a very controversial set of bits for a screwdriver. The body is made of high-strength, high-alloy steel, but in tests it only tightened 1,333 screws. But the turning radius of the torsion core here is incredible - 60 degrees. For comparison, similar equipment from other manufacturers does not exceed 15.
Overall, these are good bits for professional work. Although the edges will break faster, she is a pleasure to work with. It will especially show itself with hard wood and metal. By the way, the line has all sizes and shapes, except for the SL flat slot. This cannot be called a minus, since they are practically not used anywhere.

STAYER with 8 mm socket head 26390-08
pros
- High mechanical hardness
- Low price
Minuses
- Weak magnet
From 37 ₽
The STAYER bit with 8 mm socket head 26390-08 is convenient to use for working with threaded connections. It is made of durable chrome-plated steel, so it can withstand intense loads. The only negative that can interfere is a weak magnet.
Wera Impaktor 851/4 IMP DC
A very interesting model, which has no analogues in our rating yet. The basis of this bit is the adapter. It contains 1 more torsion bar, which increases the degree of rotation. There is almost no recoil from the impact driver.
"Vera" positions "Impactor" as the best bits with a cosmically long service life. Reinforcement of the impeller with diamond coating prevents the slot from being worn out, and the gentle movement of the 2 cores makes it easier to tighten the screws.
By the way, the color of the protective plastic depends on the slot. The dimensions are also written on it, so you don’t have to look for which bit is where.
Makita Impact Gold
Excellent professional screwdriver bits from the power tool mastodon Makita. The series received the name “Gold” because of the titanium coating, a characteristic golden hue.
In tests, it did not show a huge result, only 700 screws. But, this is a line of double-sided equipment. If the edges are erased at one end, you need to turn it over and you can continue working. The metal is highly magnetized, so the screw does not fall off.
The series includes all types of screwdriver bits, except SL (flat slot).
Varieties of design
The characteristics also depend on the type of structure.
According to this parameter they are divided into 2 types:
- Tough. The structure is completely monolithic. During operation, the bit is subjected to increased load and therefore wears out quickly, especially if it is made of a soft alloy.
- Torsion bars. The bit has a flexible part to smooth out the load and extend its service life.
Bosch Impact Control
And now old Bosch has entered the ratings. For entry-level craftsmen, they answer the question “what are the best bits for a screwdriver to buy?” It only makes sense to buy Bosch Impact Control as a set. Firstly, there are all sizes and a good bit holder. Secondly, the price for 1 unit is only 100 rubles.
But Bosch beat its competitors not only in price. The set contains bits of different lengths, so you can even disassemble equipment with it - it can handle hard-to-reach places. In addition, the equipment comes in a convenient plastic case and a container for screws.
Criterias of choice
To purchase high-quality bits, focus on the following parameters:
- Material of manufacture. Models with diamond and titanium coating are considered the highest quality. Equipment without additional coating wears out very quickly.
- Heat treatment. Hardened products last much longer.
- Alloy hardness. It is recommended to buy tools made of an alloy with a hardness of 58-60 HRC. Less hard alloys deform much faster.
- Tip type. There are many types of fastener slots, each with a corresponding bit. Therefore, you need to select a set taking into account the specifics of use.
- Mounting method. Instruments with magnetic fixation are most in demand due to their ease of use.
- Size. The slot width can be 2-9 mm, thickness - 0.3-1.6 mm. Standard length is 25-90 mm. You should select it according to your needs.
- Availability of adapters. To extend the working body and access hard-to-reach places, various adapters can be used. It is better to buy a set with such adapters due to their versatility.
KRAFTOOL 26154-H42
If you feel sorry for the money on Bosch, another German brand, Kraftul, will save you. This 42-piece set costs just over $15.
By the way, if you count the number of accessories, it turns out that there are only 41 items. For some reason, Kraftul decided to count the case itself.
The set includes good chrome vanadium cue balls and several bit holders. By the way, there are also ¼-inch to 3/8 adapters. The quality does not cause any complaints and the set is quite good even for assembling furniture or construction.
But you shouldn’t expect quality from the kit like the DeWALT FlexTorq. The bits will wear out relatively quickly, and under heavy loads they can even become screwed.
Bat manufacturing materials
The following alloys are used for manufacturing:
- Steel grades R7-R12. They are used for the production of inexpensive equipment designed for light loads and soft surfaces.
- Tungsten-molybdenum. A stronger and more durable alloy than conventional steels.
- Chrome vanadium. Bits made of this alloy are designed for significant loads and are suitable for hard surfaces.
- Chromium-molybdenum. The most durable and long-lasting products designed for professional use.
Metabo 626704000
A set with unstable quality. On the Internet, users were divided into 2 parts: those who liked the set, and those who threw mud at it in every possible way. Overall, the set is good. There are the most common sizes: 2 types of bits, chrome-vanadium alloy does not fail when working on a construction site. Depending on the slot, different pieces of paper are glued to the nozzle. Also included are 2 bit holders: magnetic and mechanical.

The set is often counterfeited, and you can even find a replica in a large store. As a rule, a fake Metabo has dry, flimsy plastic on the case, and the latches almost do not hold the lid. The bits are “plasticine” and even under light loads they curl into a screw. This is not what you want to get for $30.
Help in determining the best screwdriver attachments
To determine the best bits for a screwdriver, you can use information in construction reference books, get advice in specialized stores, or find the right site on the Internet. The latter method of obtaining information is preferable for most today.
However, you should not neglect to familiarize yourself with visual examples of various bits displayed in sets in stores and markets. Seeing and carefully examining the attachments, so to speak live, is considered by many to be a better way to get acquainted than looking at photos of screwdriver bits on construction sites.
This makes it easier to navigate the variety of types of attachments and choose the most durable, practical, and long-lasting ones.
