Abstract: A cured concrete and stone bore working tool and method of forming radially oriented discontinuities in a bore or perforation formed in a cured concrete or stone material such that, after use or application of the tool, the perforation formed in the cured concrete or stone material is configured to provide a non-planar adhesive interface and isolate a properly sized anchor or fastener from direct contact with the wall of the bore. Fasteners or anchors adhesively secured in bores previously treated with the bore treating tool exhibit improved creep failure performance as compared to fasteners adhesively secured to untreated bores.
