KSEM™ Modular Drill for the Intermediate Diameter Range

The KSEM modular drill covers drilling applications in a diameter range of 12,5-40mm (.4921 – 1.5748”) up to 10 x D. KSEM enables maximum feed rates for highest productivity.

With four large contact surfaces, the insert pocket seat provides maximum stability, even in challenging conditions like stacked plates, cross holes, and inclined exits.

The central locking screw mechanism ensures secure clamping of the insert, resulting in process safety and long tool life for both the drill body and the insert. Material specific point geometries provide versatility in a wide range of materials.

The KSEM carbide inserts can be reconditioned, further extending the tool life, reducing tool inventory and tool cost.
