MSD-Hex Step Drills are an entire drill set in one cutting tool, and a must for all professional electricians and sheet metal contractors. The model MSD-Hex-1, for example, can drill thirteen diameters from 1/8" to 1/2".

These drills feature two flutes(and two cutting edges) for fast drilling, and are Titanium Nitride coated for long life. They feature a 1/4" hex shank for use in our QCD "quick-change" driver, or for direct loading into impact-drive power tools.
