​​​WhisperKut technology​

WhisperKut is a patented technology able to significantly break up harmonics, reduce chatter and vibration.​

Body design​​

Each cutting flutes is oriented at a different helix angle with respect to all remaining flutes, allowing good stability and effectiveness in eliminating harmful harmonics.​


​Head design​

​Each flute is unequally spaced from the others, reducing the constant harmonics typically produced with conventional end mills.​​
