Modular Drills

KSEM™ Chamfer Rings

Features and benefits
  • KSEM SEF rings can easily be attached to a KSEM body to create an effective and rigid chamfering tool. This makes your KSEM tooling more versatile and saves you time on small chamfers and deburring operations.

  • High performance and quality: As a double-edged chamfering solution, KSEM SEF rings withstand the typically high feed rates of the KSEM drilling system and create high quality surfaces.

  • Reduced machining time: Combined drilling and chamfering in one shot.

  • Flexibility: Adjustable drilling depth and possibility to remove the ring if you need a plain drill.

  • Availability: All items available off-the-shelf (KSEM body and inserts, SEF ring, and SEFAS inserts).

  • For speed and feed recommendations, please refer to the catalog recommendations based on geometry and tool body length of the carrying KSEM tool.
