Ball Bearing Super Chuck
Designed for extra heavy duty drill applications such as industrial drilling machines, jig borers, milling machines, lathes, radials and CNC/NC machining centres. Each chuck features ball bearing construction to maximise the gripping force and accuracy, through hardened sleeve teeth plus hardened nose and keyholes to provide wear resistance. The centre ground jaws are specially heat treated to ensure high gripping surface hardness.
