DrillMeister – Brake disc rotor – DMP special head
IMPROVE TOOL LIFE
Drilling process for bolt hole of Brake disc rotor. The existed drill generates burrs at the end of its tool life, which limits its overall usability.
The specially designed DrillMeister DMP head, featuring a dedicated chamfer edge to minimize burr formation, has been adopted.
Improvements in wear resistance and burr control have successfully doubled the tool life.
