I've had good luck with Yonico cutters, pretty good quality. So I decided to try this Forstner bit. I bought this to drill a hole in a cedar table. It worked well enough for that. But the beat is of poor quality. There were burrs on the cutting edges of the central cutting edges, and the outer cutting surfaces were not sharp at all. It did a surprisingly decent job, but it was on cedar. I wouldn't expect it to last very long.
