ABSTRACT:
A chuck with T-slots to receive slot blocks for the attachment of stops or rests on the chuck body or on clamping jaws guided for radial movement within the chuck body by at least one attachment screw which engages into a slot block. In order to prevent throwing off of the clamping jaws even if the attachment screws are not properly tightened, the T-slot opens at its radially inward end into a continuous bore having a diameter corresponding to the width of the slot at the base of the slot and at least the base of the slot terminates at a radial distance from the outer periphery of the chuck body at the radially outward end of the slot or the base of the slot is inclined away from the face of the chuck in a direction toward the outer periphery.
