    Also known as jig bushings, these drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings.

    Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.
