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 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.

Easy to machine to close tolerances, these dimensionally stable tubes resist expanding when exposed to heat and moisture. They have a naturally slippery surface along with excellent wear resistance. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.
Tight-tolerance tubes that are 6” long are also known as bushing stock. You can slide them over rods to increase the OD, or into shafts to decrease the ID. Their precise sizing also allows ascending sizes to fit inside of each other to increase the wall thickness.
