Description

These bits simplify the task of pre-drilling holes for hinges or other screw-mounted hardware by ensuring that the hole is accurately centered every time. The precision-made hardened carbon-steel guide barrel has a beveled end that automatically aligns the internal HSS drill bit to the center of the mounting hole in the hardware. You can control drill depth by adjusting a set screw in the side of the barrel (5/64″ hex key not included). Each bit has a hex shank that fits any 1/4″ drill chuck.
