Four-way chuck key

The Tuff Stuff CK4WAY is a four-way chuck key built for electricians and tradespeople who work with multiple drill brands on site. A single tool replaces a collection of individual keys, reducing the number of items carried in a tool bag. It fits chucks from manufacturers including Jacobs, Makita, Milwaukee, Porter Cable, Ridgid, Rockwell, Rohm, Sioux, Skil and Thor.

Eighty-six chuck compatibility

The key is engineered to open 86 different chuck models across the listed brands, covering a wide spread of common professional and industrial drills. Its four-way head provides the necessary profiles to engage each supported chuck without adjustment. Chucks not included in the specified 86 models will not be operated by this key.

Capacity and limits

The tool comfortably handles routine bit changes on any of the 86 supported chucks, delivering the torque needed for standard drilling and driving tasks. It runs out when a chuck falls outside the defined compatibility list or requires a specialised profile not present on the four-way head. Users with proprietary or vintage chucks outside the specification will need a dedicated key.
