Products Details Information
Main features of carbide long twist drill bits:
1. Rod material: Choose the high-quality material supplier, control outer diameter size, precision, finer grain size, high density, and strong wear resistance.
2. Improve the surface roughness, make the coating’s adhesion better.
3. Coating, matching different coatings for different workpiece materials to maximize the effect, performance improves at least 30%
4. Pointcut: Match the corresponding drill tip according to different workpiece materials, such as auger tip, four plane drill tip, S6 drill tip, etc.
5. Cutting edge: Refined passivation value: According to different materials, the corresponding passivation treatment is carried out.
6. Flute profile: chip removal smoother
