Remove pins from workpieces by positioning the pins over the holes in these hardened steel blocks and tapping them out using a punch and hammer. Each block has a range of hole sizes to accommodate different pin diameters. The V-groove in the middle of the block allows for pin removal in the same way from round and angled workpieces. These blocks can be used as a drill guide or as an anvil for bending or forming small parts. Also known as bench blocks.
