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.

Removable Drill Bushings
Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves (sold separately). By swapping in a bushing with a different ID, you can change the size of your bit and still use the same hole in your fixture. All are made to tight dimensional tolerances for consistent, accurate results, even as you change them in and out. They're also known as slip-fixed and renewable bushings.
Choose a sleeve with a length that matches the length of your bushing. To prevent bushings from spinning inside the sleeve as you drill, pair a standard sleeve with a lock screw, or use a locking sleeve. For faster placement in and removal from sleeves, use a handle.
Lock screws thread into a hole in your jig. The head of the screw fits into a notch on the bushing's head, which keeps the bushing from spinning.
Locking sleeves act as a sleeve and lock screw at the same time. They have a raised flange that fits into the notch on the bushing's head, keeping the bushing in place. Knurled sleeves grip the sides of a hole to prevent rotation. Press or mold them into plastic tooling. Smooth sleeves are slightly oversized for a snug fit. They’re usually installed in metal tooling—press them into place with a manual or hydraulic press.
