If you have ever fiddled around trying to lay out the drilling hole pattern for a bench-mounted vise (or anything else), you know why you need transfer punches.

Instead of trying to mark the hole with a pencil (and getting it almost right), you just put one of these hardened punches in the hole and tap it to transfer the exact hole center to the material to be drilled.

Use them for hardware mounting, for jig making or as size gauges for small holes that defeat standard calipers.

Made of Rc46 ferro-blacked steel, the set of 28 punches ranges from 3/32" to 17/32" and comes in an indexed stand.
