Features and benefits

  • Drill Fix DFC inserts for KSEM PLUS B1 heads feature a rhombic shape that creates a steeper cutting angle to prevent lid generation in material stacks.

  • DFC inserts provide lateral guidance to KSEM PLUS B1 drills and good hole quality.

  • KC7140™ grade is a TiCN-based, PVD-coated alloyed carbide, ideal for machining alloyed steel and stainless steel on KSEM PLUS systems.

  • Two indexable cutting edges.
