ABSTRACT:
An apparatus for forming features in a workpiece is provided. The apparatus includes a nosepiece that engages a boss of a template and guides a tool member therethrough. The nosepiece includes a housing and an adjustable member positioned at least partially in an interior space of the housing. The adjustable member defines radial apertures that hold locking members such as spherical bearings. The locking members are configured to contact a tapered portion of the inner surface of the housing so that as the adjustable member is adjusted from an unlocked position to a locked position, the locking members contact the tapered portion of the housing and are urged radially inward to retain the boss.
