The arbor having a first end structured of a D-shaped threaded extension, and a second end structured for releasable connection to a rotatable tool chuck. The cutting member is generally concavo-convex in structure with the guide member being generally rectangular and flat with rounded terminal ends. Both the cutting member and guide member have central D-shaped apertures sized for receiving the D-shaped threaded extension of the arbor. Both the cutting member and guide member are releasably adjustably retained on the D-shaped threaded extension of the arbor with threaded nuts.
