Collection: Head Liner Bushings

Head Liner (HL) Bushings are similar to Liner Bushings, but with a head to resist heavy axial loads. HL liners are permanent bushings used to hold renewable drill bushings. The liner's ID has a precise sliding fit with the renewable bushing's OD. The liner accurately locates the renewable bushing and protects the jig plate from wear and damage caused by frequent bushing replacement. Note: the "length" listed for an HL bushing refers to its overall length, not its length under the head.
