The Wedge-Shaped Power Chuck with 3 Claws and the Super-Large Through-Hole Diameter.
The sliding surface is hardened, precision grinded and directly lubricated.
High-Rigidity Structure and High-Clamping Accuracy.
The J value is the hole diameter of an un-threaded coupling nut, and the L value is the maximum-size specification allowed for a coupling nut's thread machining operation, but they can be customized according to actual needs.
