Review on Deburring External Chamfer Stainless Countersink by James Nedumaran

The price is low, so I didn't expect much, but it's mainly props. They're so blunt you can't cut anything with them. The cut surfaces are rolled and rounded. The good news is that you can give them to your child without fear of injury. Don't waste money on them unless you just want to look at them from the outside.
