If you are working in silver and gold, losing any amount of material due to sanding is a loss of value. Making a clean hole means less cleanup and less scrap.

This is the tool you want when you have a lot of holes to punch in sheet stock and you don't want to spend time cleaning up burs. Other hole cutters leave burs, but this one is really clean. It also has a built in ejecting spring so you don't have to pry the blank off the cutter, and that saves a ton of time too. If you do a lot of metal stamping with punches, this hole punch at 1.5mm is the perfect size for jump rings and bails.
