- Six-flute design for stability: The six cutting edges distribute cutting loads to minimize vibration and ensure consistent chamfers and countersinks with each pass, even on tough materials.
- 100° countersink angle for precise chamfers: Optimized geometry creates clean starts, smooth finishes, and accurate depths with minimal deburring for a professional look.
