Features

  1. Superior Drilling Precision & Hole Quality: Optimized margin top positioning paired with an advanced three-margin structure ensures high-precision straight cutting and a flawlessly smooth surface finish.
  2. Exceptional Anti-Vibration & Optimized Chip Removal: The innovative combination of dissymmetrical irregular margins and unequal flute spacing (A≠B) effectively dampens machining vibrations while drastically improving chip evacuation efficiency.

Application

  • Excel at working stainless steel, carbon steels (~HB225), alloy steels (HB225~325), pre-hardened steels (up to HRC45), hardened Steels (HRC40~45), and cast iron.
