Boneham Pilot Bushings are designed for guiding drills for pilot holes. Furthermore, they can be used as the initial bushing in a three stage operation. Accurate three stage operations usually include piloting, drilling and reaming. These pilot bushings have standard OD sizes but small bores that fall outside the standard size range.
