CNMG 431-EM GST7115

Next-Gen Technology for Turning Difficult HRSA Materials

• High impact resistance for medium to light-roughing applications
• Open chipbreaker design reduces cutting zone temperatures for increased tool life
• New substrate processing technology provides increased hardness at high temperatures, extending tool life
• Extremely high resistance to cutting edge deformation
• Innovative Nano-Structure PVD multi-layer coatings
• Superior coating adhesion at high temperatures for more time in cut
• GST7115 is the first choice, broadest application range grade for super alloys, suitable for low to medium cutting speeds
