Description

Head Liners are similar to L 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. Complete part numbers for all standard Head Liner Bushings are listed in the tables below.
