    Very useful for sculpting in wood

    Very aggressive burr and a pleasure to use in wood sculpting in the roughing out phase of new work. All of the Kutzall burrs I have purchased have been well worth the price and have remained sharp despite many hours of use with a wide array of exotic hardwoods. See some of the results on

    Keep a stiff wrist!

    This sphere burr if awesome! In a die grinder it removes a lot of wood, but be carefull to keep a stiff wrist. Otherwise it will jump out and ruin the rim of the bowl or cup. With a little pratice, it will become a valueable addition to your arsenal of tools for carving. No other burr (that I know of) will remove so much wood as fast as the Kutzall Sphere Burr. Quality made.
