Abstract
A rotary cutting tool is formed in the shape of a wheel in which the spokes extend arcuately and downwardly to a central hub with the lower edge of these spokes having a cutting edge formed thereon or attached thereto. The spokes in addition to extending downwardly in the direction of the workpiece are curved in the vertical direction to form an upwardly slanting surface along which the material sheared off by the cutting edge may ride and be discharged between the spokes. The hub of the tool is connected to a shaft which may be rotated by a hand-held electric drill or similar device.
