Review on SE DT220R Diamond Shank 20 Piece by Emili Hudson

They work great with my rotary tool and flex shaft attachment. I had them carve, etch and generally sculpt rocks (small pebbles and river rocks for art). They worked great and I keep finding new uses for them. My mother-in-law makes stained glass and needed some diamond drill bits (she has a large glass cutter and a dremel). While waiting for her to arrive, I suggested she use my set of diamond crowns so she could try them out. She saved them and sent me $ to buy more! LAUGH OUT LOUD. Excellent product, arrived on time. And I have already recommended them to friends and family. If you're on the fence, buy them. You're worth it.
