CNC bushings are used in computer numerical control (CNC) machining to bore holes in metal and wood. Their precision gripping makes them an excellent option for drills, reamers, boring bars and other round shank tools. There are a variety of bushings depending on the job at hand, including lathe bushings and steel bushings. Though machinists and woodworkers are most likely to supply CNC bushings, they’re not the only ones—plenty of factory workers, engineers, metalworkers, carpenters and contractors have them too. In addition to CNC bushings, Zoro also has a big selection of tapered and QD bushings, keyless bushings, collard bushings and reducing bushings.
