BN7115 – SUMIBORON for Sintered Alloy Machining

Excellent stability in high-precision finishing of sintered alloy. Balance of cutting edge sharpness with fracture resistance ideal for finishing of sintered alloy.

  • New grade BN7115 : Lineup of 53 items.
  • New cutting edge treatment with an emphasis on fracture resistance : US Type now available.

Provides stable performance for high-speed finishing work with sintered alloys.

With improved CBN particle/binder boundary strength due to the special binder and improved binding strength between CBN particles thanks to our proprietary sintering process, the edge sharpness in sintered alloy machining is excellent and burrs and tearing are suppressed.
