Solid Carbide Micro Diameter Drills

1. Diameter range: D0.04~3.0mm

2. Diameter tolerance: 0-0.005mm

D1≤1.0mm Drill point angle：118°

D1＞1.0mm Drill point angle：135°

3. Ultra fine particles and super wear resistant cemented carbide are used.

4. The newly developed composite coating enhances the fatigue resistance and wear resistance of the drill bit; it is especially suitable for hole processing of stainless steel, high temperature alloys and other materials, with long service life and high efficiency.

5.Long life,high efficiency.
