Dewalt n690172 Chuck Package Including Washer Screw

Product Description

The DEWALT n690172 is a factory-replacement chuck package designed for DEWALT power tools. The kit includes the chuck assembly along with its washer screw, supplying the hardware needed to restore proper chuck function on compatible drills and drivers. This package targets the tool's front-end drive interface — the component responsible for gripping and releasing drill bits and accessories. Installation is typically performed by power tool repair technicians or experienced tradespeople completing in-shop or on-site maintenance on DEWALT equipment.

This chuck package is suited for applications where the original chuck has worn, stripped, or lost clamping force. Replacing the chuck assembly restores secure bit retention and reduces runout, which is critical on jobs requiring precision drilling or driving. The included washer screw ensures the chuck seats and secures correctly to the spindle without the need to source a separate fastener.
