G-Class Positive 3D Chipbreaker Series for Swiss Lathes MESI / MEFF / MESL Chipbreaker The MESI chipbreaker is the 1st recommendation for small product machining
MESI
Excellent chip evacuation and wear resistance over a wide range of cutting conditions for outstanding versatility
Dimpled shape suppresses heat generation due to large depths of cut
Corner Part
(Inch)
.03
Protrusion breaks chips over a wide range of depths of cut
15°
Cutting Edge
Cutting edge shape aimed at improving chip control performance and reduce cutting force in profiling
14°
