5C collets are a standard in many machine shops, but there are times when the exact size collet isn’t available or when a part requires the versatility of a 4-jaw chuck. This compact 3.1” 4-jaw chuck with a 5C back allows for a fast and easy transition from collet to chuck without disassembling your setup or switching machines. Simply remove the collet and insert this chuck into your existing 5C collet holder. Switching back to collets is just as quick. The 5C back features the standard taper, thread, and keyway, and is CNC-machined from a single billet of steel to ensure perfect concentricity between the back and the chuck body. The chuck includes reversible jaws and a chuck key for convenient adjustments.

Note: 5C collets are commonly used with full-size machines. This chuck is designed for use on full-size equipment, like those in our shop, and is not compatible with Sherline lathes.
