The different materials used in small screwdrivers will lead to different quality of the screwdriver. The selection of the screwdriver material should take into account not only the wear resistance of the blade but also the toughness of the screwdriver. Screwdrivers are generally made of alloys, and good screwdrivers generally use high-quality alloys. Commonly used materials include chromium-molybdenum steel, chromium-vanadium steel, S2 tool steel, etc. Let’s introduce what material a screwdriver is made of.

Each material has its own different characteristics. Some materials have higher hardness but are not suitable for making screwdrivers. Some materials are very suitable but the cost is very high. Some materials have good hardness, strength and toughness, but are only suitable for ordinary screwdrivers. work environment.

Screwdrivers are made of the following materials

1-Chromium-molybdenum steel (Cr-Mo)

This steel has good impact resistance, hardness and It has very good toughness and is generally used to make top-grade screwdrivers and small hex wrenches. It is an alloy of chromium, molybdenum, iron, and carbon, but the material is relatively expensive.

2-Chromium Vanadium Steel (Cr-V)

This material has good strength and toughness and is the ideal material of choice for making wrenches, screwdrivers, etc. It is an alloy of chromium and vanadium elements. It is not that expensive and is a common material for screwdrivers in daily life.

3-Carbon Steel (CS)

Carbon steel refers to a type of steel that does not add other specific elements and has a carbon mass fraction of less than 2.11. It has the advantages of high hardness and high strength. , the disadvantage is poor toughness. This steel is not suitable for use as a screwdriver, but is widely used as a general tool material.

4-S2 tool steel

This alloy is an excellent impact-resistant steel and is used to make high-hardness hexagonal wrenches, screwdrivers, etc. Tools made of this steel are heat treated to achieve a sufficiently high hardness. It has good wear resistance and has certain strength and toughness. However, the actual selection and use of screwdrivers is not as good as the use of chromium vanadium steel.

What brand of screwdriver is good?

1. Great Wall

5. SATA

SATA is a famous brand owned by Danaher Tools (Shanghai) Co., Ltd., a wholly-owned subsidiary of the American Danaher Group in China.

?A well-known (famous) power tool brand, a mid-to-high-end tool brand, a leading brand of hand tools in China, a wholly-owned subsidiary of the American Apex Tool Group in China, and a leader in the global tool industry.

Some extreme practices in factories are to use diamond coating or titanium nitride coating on the cutter head to increase the hardness and service life of the cutter head. However, the above material selection is one aspect, and the processing technology is another aspect. Bringing out the most benign aspects of the material relies on heat treatment. It is absolutely impossible to make a screwdriver based solely on the quality of the material. The hardness of the screwdriver is very high, which can cause great damage to the screws if used improperly. The hardness is too poor and the wear resistance of the screws will also be poor. Therefore, good materials and good craftsmanship are what make a good screwdriver. key.

The above is the relevant content about what material is good for screwdrivers, I hope it can be helpful to everyone!
