Specifications and Product Details:

Drill Bits for Steel 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.

HSS 4241 materials are used to make economical twist drill bits, HSS 4341 twist drill bits make common cutting performance ,The performance of HSS 9341 and HSS 6542 (M2) is good, HSS M35 drill bits is the top quality one, it can be used to drill stainless steel, for M35 HSS material contains additional 5% cobalt, which can increase the HSS material’s capability to keep its high hardness under the high temperature generated in the drilling.

All the HSS drill bits can be coated with nitride or titanium, which can improve the drill bits’ durability and cutting efficiency.
