Abstract: A punch head assembly that includes a punch head including a main body having opposite first and second ends, a longitudinal inner bore, a first passageway extending substantially radially from the inner bore, and a second passageway substantially traversing the first passageway. A ball bearing is received in the first passageway. A pin member is received in the second passageway. The pin member is rotationally movable between first and second positions. A driver is coupled to the punch head and includes a stem extending into the inner bore. The stem has an outer ball engagement surface. The punch head is axially movable with respect to the stem. Axial movement of the pin member in the second passageway moves the ball bearing into and out of engagement with the outer ball engagement surface for adjusting an axial position of the punch head with respect to the driver.

Abstract: A method of adjusting punch body assembly, that has a punch body coupled to a driver, by moving the driver with respect to the punch body until a select axial position is reached along the longitudinal axis of the punch body and locking the driver at the select axial position.

Abstract: An adjustable punch body assembly and method of adjusting a punch body assembly that includes a punch body that has a driver engagement end and an opposite cutting end, and a longitudinal inner bore the extends between the driver engagement and cutting ends. The driver engagement end includes a first adjustable engagement. A driver is configured to adjustably couple to the punch body. The driver includes a base that has a second adjustable engagement corresponding to the first adjustable engagement of the punch body to establish an axial position of the driver with respect to the punch body on a longitudinal axis thereof. A stem extends from the base for mating with a punch head. A locking mechanism is provided at the driver engagement end of the punch body for locking the axial position of the driver.
