Finishing to Light Cutting
Features
M Class
G Class
E Class
FX
Best suited for general- purpose O.D. finishing with larger depths of cut. Burrs are less likely with undercutting. Chatter is less likely with external and face machining. 3D chipbreaker with good chip control and sharp cutting edge. MEFC is for fine finishing, and the MESI is for varying depths of cut. Breaker for aluminum alloy machining. Sharp edge and low adhesion. 1.65 0.15 ST Type
