CNMG 431-LM GM1115

Superior performance in stainless steel medium turning at high speeds

• Lower cutting forces with high edge sharpness
• Precision micro-edge geometry optimized for stainless steel
• Sophisticated edgeline reduces work hardening
• Very wide application range
• GM1115 is a triple-coated MT-CVD grade, on a gradient-sintered substrate with excellent wear resistance and outstanding adhesion properties
• Post-coating treatment provides smoother cutting zone interface for reduced built-up edge and longer tool life
• Best suited for stable conditions and high cutting speed applications
