Abstract
A link is pivotally connected at one end to the collar which is clampingly engaged with the quill of a machine tool. The other end of the link is pivotally connected to one end of a lever arm. At an intermediate point, the lever arm is engagable with a conventional sensitive drill adapter held in accordance with conventional practice by the machine tool. The drill adapter is reciprocally movable in response to movement of the lever arm.
