Removable Drill Bushings for Thin Metal
Unlike most bushings, these won’t buckle the material or distort the hole when installed in thin-gauge aluminum and steel fixture plates. They’re held in place by a lock ring (sold separately), so they’re easy to remove and reuse. Also known as jig bushings, they accurately guide drill bits, counterbores, reamers, and other cutting tools. Use them to make sure your drilled holes and cuts are consistent from part to part.
