TN610 / TN620 / PV710 / PV720

Cermet and MEGACOAT Cermet
for Steel Machining

New cermet for high quality surface finish machining with excellent wear and fracture resistance to improve tool life.

  • P


TN610 / TN620 Uncoated CERMET

  • TN610 with higher wear resistance during continuous and finish machining
  • High quality / High precision machining
  • TN620 for general use and quality surface finishes with balanced wear and fracture resistance
  • Excellent fracture resistance with surface-hardened layer using gradient composition technology
  • Continuously-varied hardness provides wear and fracture resistance
  • Combining the conventional cermet bonded phase (nickel, cobalt) and the special high melting point metallic bonded phase improves adhesion resistance and provides a better surface finish with a higher thermal resistance of the bonded phase


  • PV710 for long tool life during high speed and continuous machining
  • PV720 for high efficiency machining and superior surface finish
  • Improved strength with uniform micro grain hard phase and superior compressive stress with high melting point bonded phase with a resulting combination that yields greater fracture resistance
  • Excellent surface finish
