ABSTRACT:
A rotary disc rasp formed from a dish shaped rigid metal plate. Holes are punched or drilled through the plate in the direction of rotation and the rear edges of the holes are forced outwardly relative to the convex side of the plate to provide cutting teeth thereon. The cutting teeth define a curved cutting area on the plate whereby engagement of the cutting teeth with a work piece can be controlled. The plate is preferably mounted to a right angle grinder which rotatably drives the rasp for controlled removal of material as required for shaping and fitting in a sculpture or construction operation.
