HM 55-30 42.00 Head Press-Fit Liner Bushing, Metric
Description
Metric Head Liner Bushings are simply specific large ID sizes of HM Head Press-Fit Bushings. 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. Note: the "length" listed for an HM bushing refers to its overall length, not its length under the head.
