ABSTRACT:
A driving center assembly is provided wherein a work engaging center pin has a bore containing a ball compressed against the flat face of a hemispherical member housed in a socket in the drive shank. The center pin passes through a drive plate which is made rigid with a drive plate through push pins which are urged against the hemispherical member thereby allowing the drive plate and pin to tilt for out of square surfaces by insuring that the push pins exert equal pressure in forcing the drive pins into the work piece.
