Patent ID: 8707542

Claim:
A rotary cutting tool for trimming the surface of a work piece, the tool comprising: a chain saw having a chain guide bar with a first longitudinal axis extending in a first direction; a cylindrical cutter mounted to the chain saw and positioned such that a second longitudinal axis of the cylindrical cutter extends in a second direction orthogonal to the first direction, the cylindrical cutter rotatable about the second longitudinal axis; a saw chain of the chain saw engaged with a sprocket that is rotatable relative to the chain saw about the second longitudinal axis such that the chain saw, the saw chain, and the sprocket are used for causing the rotation of the cylindrical cutter; a plurality of mutually spaced apart cutter teeth fixed in a uniform pattern on an exterior surface of the cylindrical cutter; wherein the cylindrical cutter has a plurality of portions that are secured to a common drive shaft that is rotatable about the second longitudinal axis, wherein two of the portions are separated by the sprocket, and wherein on opposing sides of the sprocket along the second direction, two of the portions are separated by a respective brace and bearing holder for supporting the common drive shaft; whereby, the saw chain operatively rotates the cylindrical cutter thereby moving the cutter teeth in cutting action against the work piece.
