Jobber Drill Bits are cutting tools used to create cylindrical holes. Bits are held in a tool called a drill, which rotates them and provides torque and axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes. They are designed with high speed steel to get more power to create holes.

High Speed Steel have many grades. In China, the most popularly used are HSS 4241, HSS 4341, HSS 9341, HSS 6542 (HSS M2), HSS M35.The numbers of these grade codes represent the approximate percentages of tungsten, molybdenum, chromium and vanadium in the HSS material. For instance, HSS 4241 — W4Mo2Cr4VSi, HSS 4341 — W4Mo3Cr4VSi, HSS 9341 — W9Mo3Cr4V, HSS 6542 — W6Mo5Cr4V2. HSS M35 contains additional 5% cobalt on the base of HSS M2.
