The Irwin Installer Drill Bit combines fast, accurate drilling through wood with built-in wire-pulling capability. A hole in the tip lets you attach a wire, cable, or pull string and draw it back through as you withdraw the bit - saving time when running electrical, data, or audio cables through walls, ceilings, and floors. The 3-flatted shank prevents slipping in the drill chuck for consistent, reliable driving.
