Back to Full-Size Chucks
5C 4″ 4-Jaw Independent Chuck
5C collets are widely used in machine shops, but there are times when the exact size collet isn’t available, or when a part requires the flexibility of a 4-jaw chuck. This 4” 4-jaw chuck with a 5C back allows you to quickly switch between a collet and a chuck without disassembling your setup or moving to another machine. Simply remove the collet and insert the chuck into your existing 5C holder. When you’re finished, you can just as easily switch back to collets.
The 5C back features the standard taper, thread, and keyway, and is CNC-machined from a single billet of steel to ensure concentricity between the back and the chuck body. The compact 4” chuck comes with reversible jaws and a chuck key for easy adjustments.
Note: 5C collets are designed for use on full-size machines. This chuck is intended for use with such machines and is not compatible with Sherline lathes.
