Press-Fit Drill Bushings
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.

Press-Fit Reamer Bushings
With ID tolerances sized specifically for reamers, these bushings ensure steady and precise hole finishing. Press them into a fixture plate with a manual or hydraulic press for permanent installation. Also known as headless bushings, these ANSI-type P bushings don’t need counterboring to be mounted flush. They are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

Thin-Wall Press-Fit Drill Bushings
Drill holes close together. These bushings have a thinner wall than typical bushings to fit side by side in a fixture plate. Also known as jig bushings, they precisely guide bits and other cutting tools to ensure holes and cuts are consistent from part to part. You can also use them as spacers, shims, and machinery bushings. Made of hardened, ground steel, they resist wear and last for many cycles without needing to be replaced. Since their wall is so thin, these bushings may be slightly oval when you receive them but will conform to the shape of your hole.
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.

Press-Fit Drill Bushings with Head
A flanged head on these bushings acts as a stop, so they won’t press through your jig even under extreme drilling pressure. They’re ANSI Type H bushings, also known as headed bushings. The head adds support and protects the jig from damage caused by heavy use, so they’re often used in jigs made of thin or soft materials. These bushings guide your drill bit, reamer, or other cutting bit to create accurate, consistent holes from one workpiece to the next. They’re also used as spacers, shims, and machinery bushings. Made of hardened, ground steel, they hold their shape and resist wear, so they last for many cycles without needing to be replaced.
To install, fit the bushing into a hole in your jig. In a standard hole, the head will sit above the jig plate; to mount flush, install in a countersunk hole. A chamfered edge on the bottom of the bushing helps center the bushing in the hole. Once it’s centered, press the bushing into place with a hydraulic or lever press.
