CNMG 432-EL GST7130

Next-Gen Technology for Turning Difficult HRSA Materials

• Low cutting force chipbreaker design ideal for semi-finishing operations
• Curved cutting edge provides superior chip formation at light depths of cut
• Good choice for thin-walled parts or long overhangs
• 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
• GST7130 is the first choice grade for toughness-demanding applications, including interrupted cuts and unstable conditions. Best suited for low cutting speeds.
