    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.

    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.

    Smooth

    Lock 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.
    Smooth—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.

    Strong-Hold Drill Bushings for Plastic

    Designed to grip slippery plastic, the knurls on these bushings keep them from spinning while you drill. Their hold is stronger than serrated bushings, so they can withstand more force. Press or mold into plastic tooling to guide your drill bit and create accurate, consistent holes.

    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.
