i first bought one of these back in the late 90s, on the advice of a friend who really knows how to shape wood. I was building a custom stock for a target air rifle using mainly rasps and scrapers, and my friend advised me that these bits easily carve through wood without excessive grabbing or tearing the surface. They cut very fast, too, using a light touch that doesn't load down the motor on your Dremel tool, and they last a long time. The price may seem high compared to, say, those little sanding drums that come with Dremel tools, but this bit will outlast dozens of the tiny drums and cut a lot better, too. Do your shaping with this bit, and save the little drums for finish wirk with fine grits.
