Oversize shoulder bushings are available in standard and short shoulder profiles and available in steel, bronze and bronze-plated materials. They are often used in special die sets in conjunction with oversize shoulder guide posts shown on page 6. The press fit diameters of these bushings are the same as the press fit of the outside diameters of the oversize shoulder posts, thus the same hole may be bored through the punch and die holder. The press fit diameters are 0.0075" oversize to allow grinding stock to fit the bored hole.
The steel or bronze bushings may be ground for tap fit and installed with clamps and screws or may also be ground for a press fit. The bronze-plated bushings are for use as demountable bushings only and are supplied with the appropriate number of clamps and screws. These bushings should not be honed. If more clearance is desired, it is recommended to grind the working diameter of the shoulder guide post.
