Subland Step Drill Bit: 3/8-16, 5-7/8" OAL MPN:370 3/8-16

The subland step drill bit is ideal for creating pilot holes that allow quick switch from screw driving to fastening. With a reduced shank diameter, this 3/8-inch by 16 inch long tool can cut through mild steel, stainless steel, aluminum or titanium up to 0.25 inch thickness with its stepped design that eliminates stripping when starting the screw. This multi-purpose bit offers an advantage over conventional drill bits for manufacturers, machinists or fabricators seeking high precision work where threaded fastenings must align perfectly with pilot holes on assembly lines.
