Abstract
A surgical cutting tool for cutting a seating surface of curved contour configuration in natural bone for receiving a component of a prosthetic implant at an implant site. The tool has cutting blades in a cutting blade construct placed within an arbor such that the cutting blades are supported by the arbor circumferentially spaced from one another, with cutting edges of the cutting blades exposed for cutting the seating surface. Stabilizers along the arbor stabilize the tool during a cutting operation, while channels in the arbor along the cutting blades carry away cut bone. The cutting blades are essentially flat, are economically manufactured from flat stock, are provided with a predetermined thickness and a cutting blade radius, and include cutting edges placed within the cutting blade construct circumferentially forward of the cutting blade radius to establish a gap between the cutting blade radius and a corresponding radius of the seating surface for providing an effective cutting profile along each cutting edge.
