Liner Bushings (L)

Drill Bushings

Product Information

Liners are permanently installed 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.
