Modular Drills
KSEM PLUS™ B1 Heads • Drill Fix™ DFC™ Inserts • DPA Guiding Pads
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.
