ABSTRACT:
A tap chucking means is provided which is adapted to automatically stop rotation of a tap at a predetermined depth and to pull the tap out from the work by reversing the rotation of the spindle. A cylindrical body has a bore in one end in which a socket shaft is slidably and rotatably mounted. The socket shaft is adapted to mount a chuck at its exterior end and is resiliently biased into the body. A clutch pin passes transversely through the socket shaft and has beveled inner faces on both ends of the pin. A pair of drive pins are disposed along opposite sides of the socket shaft for engagement by the clutch pin and are axially slidable in axial grooves formed longitudinally in the mid-portion of the cylindrical body. The drive pins are resiliently biased towards the open end of the body.
