Model AT Hardened Top Reversible Jaw Chucks

Semi-Steel Body

The AT chuck is based on the original Buck Chuck Ajust-Tru® design that has been copied by so many. The updated design features a larger thru-hole and a higher-quality cast iron material than the copies supplied by the competition.

The AT Semi-Steel Body Manual Scroll Chucks are available in 3 and 6 jaw master and top reversible options. These AT Manual Scroll Chucks in Ajust-Tru® Style come with the American Standard Tongue and Groove Master Jaws allowing for greater flexibility in your choice of top tooling. And, the semi-steel body of the Manual Scroll Chuck allows for a quality chuck at a lower price.
