Slip-fixed/renewable (SF) drill bushings, also known as removable drill bushings, can be removed and replaced when worn. They are ideal for applications where bushings need to be changed between tasks or where bushings are expected to wear out before the job is done. Drill bushings are installed into a drilling jig to guide, support, and position a drill or other cutting tool during metalworking tasks. They keep the cutting tool from wandering or bending as it enters the workpiece, maximize chip clearance, and minimize the risk of marring the workpiece or the jig. Type SF drill bushings are secured in a jig using liner drill bushings and lock screws.
