A rotary stone cutting tool and method for making countertops and the like includes a shank shaped for detachable connection with a rotary drive. A cup-shaped cutting blade is mounted on the outer end of the shank, and has a frusto-conical sidewall and an outer marginal edge with axially protruding cutting teeth. A plurality of cutting pads are embedded in the sidewall and protrude radially outwardly therefrom. The blade is advanced through a stone slab with the sidewall oriented generally perpendicular to the face of the stone slab to cut an arcuate portion of an inside corner with reduced waste.
