3″ 4-Jaw Chuck with 5C Back
The (independent) 4-jaw chuck is great for use with a lathe or grinding setup when parts are small and when accuracy is critical beyond the tolerances of a collet. By carefully adjusting each jaw individually, parts can be indicated in to perfect centering alignment. It is also useful when a collet of the right size is not available. In addition, the jaws are reversible for holding larger work. This provides a useful, broad clamping range for holding small parts. Slightly pre-loaded jaws provide for the ultimate in accuracy. A chuck key is included.
