FB / FENegative M Class Chipbreakers for Low Carbon and General Steel Turning

Type P

Steel

  • The FE type main breaker for finishing achieves stable chip control over a wide range of feed rates for low carbon steel and general steel.
  • Item range covers a wide variety of machining applications.
  • The FB type for low feed finishing increases chip strain and thereby improves chip breaking performance thanks to the variable rake angle in the nose radius.
