Chipbreaker Features Application Cuting Edge
SF Large rake angle reduces cutting force.Less burring achieved by diminishing damage from notching.
MP Exellent chip control when finish cutting.Outstanding chip control when high feed turning at small depth of cut.
GM Applicable to a wide range of cutting condition with sharp edge.Recommended chipbreaker for stainless steel turning.
MM

Developed chipbreaker for medium

cutting.

Excellent chip control due to wide,positive chip flow zone.
