Multi-Diameter Step Gundrills
Many parts require as many as two, three, or four various size holes in a single bore. Certain applications may allow a single multi-diameter gundrill to produce all or some of these holes, reducing machining time.

Solid carbide tips ground to print tolerances enables multiple diameters to be produced in a single pass.
