• Cutting conditions are the same for coated and non-coated inserts. • The use of coated inserts enables better surface finish and extended insert life • Lower the cutting speed if the maximum chamfering amount is exceeded • If plunge cutting produces long chips, use step feed • We recommend the use of a high-rigidity holder for chucking (HMC, MEGA-D etc.) • Max. chamfering amount for the 30°, 60° and Universal Types marked with is the chamfering length of the longer side
