Abstract
An improved device and method for use in machining a workpiece, which includes a tool body with a machining tool having two machining surface, wherein one of the machining surfaces is being selectively movable between a retracted position and an extended position. A supporting mechanism is sized and configured to substantially restrict movement of the machining tool relative to the tool body while the one machining surface is positioned in the retracted position. Preferably, the supporting mechanism includes an interior surface having a frustoconical-shaped tapered configuration, and the reciprocable machining surface has an engageable surface sized and configured to be frictionally engaged against the interior surface. In a preferred embodiment, the interior surface has an angle relative to the longitudinal axis of the tool body from about 20 to about 50 degrees, and more preferably about 40 degrees. A drive mechanism can be disposed in the tool body for selectively and quickly moving the machining tool from its retracted or supported position for movement to its extended position.
