10.75 mm ID Bearings | McMaster-Carr

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that 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. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. Since the bushing is sized slightly larger than the hole for an extremely tight fit, it’ll stay put permanently. These are ANSI Type PM bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.

They also have an internal chamfer that makes it easy to insert bits, pins, and punches without damaging the bushing or misaligning tools. Don't see the size you need? Additional sizes are available.
