The Makita D-40107 is a straight flute step drill bit made of High Speed Steel (HSS), with a diameter range from 4 mm to 32 mm. Its conical profile allows multiple hole sizes to be produced from a single bit, making it ideal for softer or thinner materials as well as enlarging existing holes. Designed for ferrous metals, non-ferrous metals, and sheet metal, the bit features a 10 mm round shank for compatibility with most drills and screwdrivers.
