MK · RK Chip Breaker


MK chip breaker improves cutting performance and reduces cutting load during cast iron machining, leading to higher wear resistance and quality surface finish at high speed and continuous cutting. A wide supporting area was designed for solving unexpected tool breakage and edge chipping due to vibrations during machining, improving stability.

RK chip breaker features wide lands and supporting area that provide excellent toughness and fracture resistance under high cutting force such as high depth of cuts or high interruption. Its land was engineered to optimize edge toughness and cutting performance, and achieve stable tool life and higher chipping resistance for high feed applications.
