Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Avoid wear caused by repeatedly pressing bushings into your jig fixture. Instead, press fit these sleeves into the fixture one time, and then swap bushings with different IDs in and out to change the size of your bit.

Use these sleeves to create a permanent base for bushings, so you can swap sizes or replace worn bushings without damaging your jig. Also known as headed liner or HL bushings, they have a flanged head that stops them from pushing through the jig when you drill.
