PURPOSE: To provide a bevel saw capable of easily removably stripping a waste coating material coating a concrete foundation floor surface by attaching radially a plurality of hard cutter materials to the front side slant surface of a shallow conical base body and projecting a plurality of cutting edges having an acute angle from the peripheral edge of the bottom.

CONSTITUTION: This bevel saw is provided with a shallow conical base body 1 formed of a casting body of aluminum, copper alloy or the like having large strength and relatively liable to be worn. Cutter materials 2 of tungsten carbide are fitted in shallow grooves radially inclined on the front side inclined surface of the base body 1 to be fixedly welded thereto. This cutter material 2 has the projecting edge line 3 projected higher than the surface of the base body 1, so that a cutting edge 4 having an acute angle can be protruded from the peripheral edge of the bottom corresponding to the mount surface of the acute angle. This bevel saw is set such that the peripheral edge of the shallow conical opened bottom makes direct contact with the surface of the base floor, and used to strip and remove waste coating materials coating the surface of the base floor by the rotation and movement of the bebel saw.
