Drill Crown chamfers and drills in one operation.

Drill Crown chamfers and drills in one operation.

M-geometry crown, for CrownLoc(TM) drill system, is optimized for hard-to-drill materials and incorporates chamfer module that utilizes 2 inserts, each with 2 cutting edges. Heat generation is minimized via small edge preparation. Sharp cutting edges and conical front rake clearance reduce workpiece work hardening, while cutting geometry reduces residual stress and minimizes burrs at hole exit....
