King Size Versatility

The Forkardt QLC-KS large bore three jaw wedge style power chuck is designed for applications requiring a larger through hole bore to handle larger diameter work pieces.

The proportion between the through hole and the outer diameter of the chuck body is engineered to provide optimal stability.

The shorter, multiple profile jaw guides allow the QLC-KS King Bore Power Chuck to have a 40% larger through hole than comparable chucks. The QLC-KS power chuck is available in sizes ranging from 200 mm (8“) to 400 mm (15“).
