The new Sumiboron grades are highly precise and very efficient thanks to new technology

With BNC2115 and BNC2125 we have optimized the coating, substrate and cutting edge design for you. As a result, they have outstanding properties that make turning hardened steel even faster, more efficient and more economical for you. You get multi-edged indexable inserts that work very well, even at high speeds. As a result, you achieve excellent results in less time. In tests we achieved 30% less flank wear.

The highlights of the new products:

  • Highest quality: With BNC2115 you achieve very high surface finishes.
  • The allrounder: BNC2125 is the first choice for general hard machining
