Product Description	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. Don't see the size you need? Additional sizes are available.
