The punch has an elongated, solid blow transmitting member with a blow receiving surface and a shank. A sleeve is slidingly carried by the shank and movable from a position protruding past the lower end of the shank. The sleeve has a sidewall with at least one elongated slot extending therethrough.

Abstract: A vacuum blast adapter for removing corrosion from the booster wells of bombs and the like which includes a cylindrical body portion having a vacuum tight seal at its forward end for engaging the outer surface of the bomb. An air/abrasive carrying line is sealably inserted through the rearward end of the body portion to guide the abrasive into the bomb booster well. An observation window is provided at the top of the adapter and a funnel collector is positioned at the bottom to collect the used abrasive which is carried away by a vacuum line. An overhead spring suspension system facilitates the movement of the adapter to successive aligned bombs.
