Drill bushings are used to guide drills and other tools. A bushing may be attached to the drill or rotary tool, or inserted into a jig to control hole location and depth. 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 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.
There are several ways in drill bushings function. A drill guide is capable of providing accurate drilling even at angles up to 45°. A drill guide is made of anodized aluminum and a standard drill bit of size 3/16" connected to the drill guide. In a drill and tap guide, the drill guide helps to drill precise holes at angles to the surface and the tap ensures that the same hole would be tapped at exact angle to provide better tapped holes. A drill bit guide is available with a drill bit size of 5/64". A drill bit guide ensures exact alignment while drilling holes in hinges and other ironmongery.
Drill bushings are used in various industrial applications for machining plastics, metals, and other materials.
