What engineering process is used to make a screwdriver?
To make the steel rod, wire is machine-drawn to the appropriate diameter, annealed (heat-treated), straightened, and then cold-formed to the proper shape. The cold forming press cuts the wire to the desired length and forms the tip of the screwdriver and the “wings” that will fit into the handle.
How the screwdriver is specified?
A screwdriver is classified by its tip, which is shaped to fit the driving surfaces—slots, grooves, recesses, etc. —on the corresponding screw head. Proper use requires that the screwdriver’s tip engage the head of a screw of the same size and type designation as the screwdriver tip.
What is the raw material of screwdriver?
The screwdriver shank is made of tough steel, and the tip is hardened to minimize wear. The handle is made of wood, metal, or plastic.
What type of steel is used for screwdriver?
Cr-V steel
In the hand tool market, the most popular steel used for screwdriver bits is Cr-V steel, such as SAE6150 steel. The hardness of a screwdriver bit made by Cr-V steel is about HRC52 ±2, and the torque value is around 180~190 kgf·cm.
What material is best for screwdrivers?
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.
Which metal is used in screwdriver?
The raw materials steel wire, plastic, nickel, and chromium are used to produce screwdrivers. The steel wire is used to make the screwdriver bar, plastic is used to make the handle, and either nickel or chromium is used to plate the steel tips of the screwdriver.
