Hanson Step Drills save time by eliminating the need to change drills when drilling round holes in thin materials. Each smaller size drill also acts as a pilot for the next size. The single radial flute assures perfectly round holes. Use on steel brass aluminum and other thin materials. Step Drills are self-starting and will not slip.Drill diameters etched in flute for easy identification.
