Kyocera SGS 12mm 42733 Ti-Namite-X Solid Carbide High Performance End Mill

Z-Carb AP end mill offers three stages of chatter suppression, resulting in the quietest, most stable milling experience available. With conventional end mills, the cutting teeth entering and exiting the material creates a natural rhythm that results in damaging harmonics. Harmonics produce a frequency that resonates through the entire tool, resulting in one of the most damaging forms of cutter wear known as chatter. Chatter degrades the quality of finish. Until now, your only choice was to adjust your operating parameters to account for the limitations of conventional end mill.
