HARFINGTON 4pcs 10mm,12mm Leather Hollow Hole Punch 1/4" Hex Shank for Drills, Belt Hole Punch Punching Cutter Tool for Leathercraft Working

I used these to cut holes in some decommissioned fire hose. They did a good job in a very tough material. Clean holes and no noticeable dulling of the cutting edge.

These punches are going to make putting holes into leather projects so much easier, already lining up the work to get need jobs done, no more banging with hammers and conventional punches, excellent selection of sizes.
