Lexair's wrench-operated collet chucks have a universal flat-back design for any application, but are well-suited for hybrid CNC/manual lathes. They do not require a drawbar or cylinder and operate manually with a standard chuck key. The Lexair chucks come in types 5C, 16C, 3J, and 22J with 1 ¹ /16, 1 ⁵ /8, 1 ³ /4, and 2 ¹ /4-in. capacities.
