Product details:

The Z-Carb-AP offers performance so advanced, it goes way beyond typical high performance carbide end mills. With most 4-flute end mills, the cutting teeth enter and exit the material creating a natural rhythm that results in damaging harmonics. The harmonics produce a frequency that resonates through the entire end mill, resulting in chatter. With its patented, one of a kind geometry, the Z-Carb-AP offers three stages of chatter suppression. Model # SGS 36482 Features: Superior chatter suppression through advanced patented design Increase productivity by cutting deeper and wider without harmful harmonics Lower cutting forces for dramatically longer tool life With Patented Variable Rake,Hardware Tools,SGS Tool Co.
