Hollow Punch for Knock-out Blocks, D16P

A HOLLOW ROD FOR USE WITH A KNOCK-OUT BLOCK. Inner diameter of .140" (3.49mm) and 3" (76.2mm) length allow it to be used to push out feeds with fill tubes still attached. Made from 304 Stainless tubing, plug drawn with TIG welded seam and hard temper. This punch is designed to fit over every Sheaffer, Parker, and Eversharp fill tube I could find. The fill tube is a thin tube projecting from the back of the feed which would be destroyed by a solid punch when using a knock-out block. Knock-out blocks found in early Parker tool kits used these hollow punches, but mine will accommodate fatter fill tubes while having the same outer diameter allowing these to fit into smaller sections as well as the large ones. This improved design punch received rave reviews from Susan Wirth.
Currently comes in Stainless.
