Feature:

Quality assurance
Large chip removal
Universal chamfered round shank
Tungsten carbide
TIAN coating on the blade
Fully sharpened
 
 
Advantage:
Large chip removal, changing core, more stable. The large core diameter is ensured under the condition of cutting capacity, which greatly enhances the rigidity and shock resistance of the drill bit, and reduces the disconnection.
 
Large chip removal rate, exquisite spiral groove, avoid sticking of drill, greatly improve production efficiency
 
The universal chamfered round shank has good compatibility. Enhance the anti-vibration and cutting speed of the drill bit, and the clamping will be tighter without slipping
 
 
Use:
Aviation Manufacturing
Machine Production
Car manufacturer
Mold making
Electrical Manufacturing
Lathe processing
