WhisperKut™ Technology

WhisperKut is a patented technology that breaks up harmonics and minimizes vibration for stable, chatter-free milling.

Body Design: Each flute is oriented at a different helix angle to enhance harmonic disruption and boost stability.

Head Design: Unequally spaced flutes reduce constant harmonics and deliver smoother, quieter performance.
