An extra-long 45# carbon steel bit with a hole through the flute, made for running wire through walls and framing.
An extra-long 45# carbon steel bit with a hole through the flute, made for running wire through walls and framing. Feed the cable through the hole, pull it back with the bit, and the run is finished in one pass — no fishing, no second hole. Ten sizes span 1/4" to 1/2" diameter and 10" to 18" length, covering interior walls, stud bays, joists and ceiling voids. Simple one-piece construction means fewer failure points, fast hole formation and consistent hole quality, run after run. Factory-direct from a 20-year precision-tools manufacturer with ISO 9001 / 14001 / 45001 triple-system certification.
