SGS Tool Company, the leader in high performance tool design, offers the Patented Z-Carb-AP Variable Rake End Mill designed specifically for superior chatter suppression. With most 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 tool, resulting in one of the most damaging forms of cutter wear known as chatter.

The Z-Carb-AP, with its patented, one-of-a-kind geometry, offers three stages of chatter suppression resulting in the quietest, most stable milling experience available.

In Stage One, unequal flute spacing helps to disrupt the rhythmic pattern created by the cutting edge of typical end mills, which helps to suppress the development of damaging harmonics.

In Stage Two, the patented unequal helix design aids in eliminating the damaging harmonics that occur during typical machining by changing the angle at which each cutting edge enters and exits the material during the milling process.

In Stage Three, the rake angle determines the size and shape of the chip, as well as the pressure and temperature of the cutting zone. By incorporating the SGS Patented Variable Rake Geometry, the Z-Carb-AP can alter and control the cutting dynamic like no other tool available, which takes chatter suppression to a whole new level of advanced productivity.
