See this chuck in action. Watch the video, above!
The patented Snappy quick change chuck accepts all tools with a 1/4in hex power bit shaft, allowing fast changes between drilling and driving. Durable all steel construction, heat-treated for excellent wear resistance and strength. Simply pushing the bit in will lock it firmly into the drive channel with a hardened chrome ball bearing. Pulling back the knurled sleeve allows the tool to be quickly removed with just one hand.
