Prime Quality HSS Titanium Coating Step Drill Bits for Hole Drilling

Step drill bit is a drill bit that has the tip ground down to a different diameter.The transition between this ground diameter and the original diameter is either straight, to form a counter bore, or angled, to form a countersink. The advantage of HSS M2 Step Drill Bit is that both diameters have the same flute characteristics, which keeps the bit from clogging when drilling in hard metal.
