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