# Drills a 3/8" diameter hole and requires a 1/4" pilot hole
# Includes allen wrench to remove center shaft with swivelling eyelet
The hollow-bodied Rebore-Zit drill bit has a removable center shaft with a free spinning, swivel eyelet at one end. Just secure your existing wire onto the swivel eyelet and re-drill your hole to a larger size. The wire will stay attached to the bit without twisting. The removeable center shaft can also be used to feed wires through drilled holes.
