This offers excellent chip control at small depths of cut. Uniquely designed chipbreaker reduces the forces and delivers exceptional chip control in a wide range of conditions. Versatile chipbreaker for medium. Sharp edge and special chipbreaker provides outstanding chip control. Suitable for a wide range of applications from continuous to interrupted. This chipbreaker combines sharpness with high fracture resistance. for round inserts. RS chipbreaker allows excellent chip control with large rake angle to curl chips smoothly. for round insert. Suitable for medium with small depth of cut and high feed. *CNMG432-HMM CNMG433-HMM.047 CNMG542-HMM.031 CNMG543-HMM CNMG544-HMM *Note: cross sections are of insert marked * : Stocked items
