Guide Bushings and Drill Bushings

Guide bushings and drill bushings are used to guide drills, punches, pillars or other tools. A bushing may be attached to the drill or rotary tool, or inserted into a jig to control hole location and depth. Bushings are used to guide leader or ejector pins on injection molds or punches on presses. A drill guide is used for precise and accurate hole drilling. There are many types of a drill guide. Examples include a drill and tap guide, drill bit guide, punch guide, and pillar guide. A drill and tap guide consists of an elongated body in longitudinal axis with the top and bottom and two sides. A drill bit guide is a self centering guide that is featured with a spring loaded end used to locate hinge screw holes and a HSS twist drill bit. A punch guide is used to punch thin plastic, metals, and paper. A pillar guide consists of a revolving drill bit which moves against the clamped material on which the hole has to be made. A drill bushing that is attached to the drill is used to connect or hold two parts together and the ejectors pin can be made of various metals. Other guides and drill bushings are commonly available.
