Description / Basics
A drill bushing is intended for precise centering, positioning and guidance of drills. They can be used in drilling rigs or for multi-spindle drilling heads as well as a drilling jig. Therefore, it is possible to create an accurate and recurring bore at the same position in one component. In addition, through the guide the drill bushing protects the drill from breakage. The most common bushings are the collar drill bushing according to DIN 172 and the cylindrical drill bushing according to DIN 179.
Drill bushings and collar drill bushings are available in a variety of fastening types. They can be pressed in or secured with a semi-circular notch in the collar of the plug-in fulcrum pins. Since it is not pressed, this has the advantage of quick interchangeability. MISUMI also offers the special form of a flanged bushing with mounting flange.
Collar bushings with oval bores are also available at MISUMI. These are provided with a semi-circular notch in the collar, which, in combination with a dowel pin, serves to align the collar drill bushing.
Drill bushings are often used as positioning bushings or centering bushings.
Due to the rounded insertion of the drill bushing, it can serve as a joining opening for centering pins or height adjusting pins.
