Shop Fox M1061 6" 4-Jaw Independent Jaw Metalworking Chuck

"Independent" means that each jaw moves independently. Such 4-Jaw metalworking chucks are used for holding odd shaped pieces or where zero tolerance is required. This 6" 4-jaw chuck with a 1-1/2" bore has semi-steel bodies and hardened reversible jaws. Requires a mounting plate. Note the mounting holes through the back of the chuck. This is because each jaw moves independently and there is no scroll in the middle.
