What is the best material for a screwdriver?


The different materials used for the small screwdriver will make the quality of the screwdriver different, and the choice of screwdriver material should take into account the wear resistance of the bit and the toughness of the screwdriver. Screwdrivers generally use alloys, and good screwdrivers generally use good alloys. Commonly used materials include chromium-molybdenum steel, chromium-vanadium steel, and S2 tool steel. Let us introduce the characteristics of these materials.

What kind of steel are screwdrivers made from?


What is a screwdriver made out of?

What steel is best for screwdrivers?

1-chromium molybdenum steel (Cr-Mo)

The impact resistance of this steel is very good, hardness and toughness are very good, generally used to make top screwdrivers and small hexagonal wrench materials, chromium, molybdenum, iron, carbon alloys, but the material is more expensive.

2-chrome vanadium steel (Cr-V)

This material has good strength and toughness and is an ideal material for making wrenches, screwdrivers, etc. It is an alloy of chromium and vanadium. It is not as expensive as it is. It is a general-purpose material for screwdrivers in life.

3-Carbon Steel (CS)

Carbon steel refers to a type of steel that does not add other specific elements and the mass fraction of carbon is less than 2.11%. The advantage is high hardness and high strength, but the disadvantage is poor toughness. This steel is not suitable for use as a screwdriver, but it is widely used in some general tool materials.

What is the best material for a screwdriver?

S2 tool steel is alloy is an excellent impact-resistant steel, used to make high-hardness Allen wrenches, screwdrivers, etc. Tools made of this steel have a sufficiently high hardness after heat treatment. Possess good wear resistance, a certain strength, and toughness. But in the actual selection and application of screwdrivers, it is not as good as chrome vanadium steel.

The above are some of the selections of screwdrivers. Some extreme methods in the factory are to use a diamond coating or titanium nitride coating on the bit to increase the hardness and service life of the bit. However, the above selection of materials is one aspect, and the processing technology is another aspect. The most benign point of the material is displayed by heat treatment. It is absolutely impossible to make a screwdriver based on the quality of the material.

The hardness of the screwdriver is very large, and it will be damaged if used improperly. Too bad hardness will also make the wear resistance of the screw worse. Therefore, good material and a good process are the keys to making a good screwdriver.
