Review on 🔪 High Speed Polished Diameter Cutting Tools by Drill America by Marcos Oner

Seems pretty good. Used to cut a soft jaw groove for clamping round work pieces, but even a larger work piece is really loose! This thing slices way too much at the end of the ball. Something is wrong with the grinding. If you need to round an inside corner, that's fine. If you want a 1/2" round bottom groove, keep something about half an inch in diameter, forget it!
