DIN1897 HSS Roll and Forged Metal Drill

 

Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. 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.

1. Material:high speed steel 4241, 4341, 6542(M2), M35(cobalt 5%), M42(cobalt 8%)

 

2. Standard: DIN 338 / ANSI  Jobber Length
3. Manufactring: Roll forged& edge polished, Fully ground, Roll forged and Milled.

 

4. Angle point: 118°or 135 split point

7. Diameter: 0.5mm to 30mm

 

Hot roll forged flute and special heat treatment gives additional toughness.

 

For drilling cast steel, malleable iron, sintered metal, non-ferrous metal etc.

 

Surface finishing will highly improve the drill bit’s life span.
