Anchor and method of using the same

A kit for embedding an anchor into a substrate, the kit comprising:

• a cutting tool for developing an undercut region in a borehole, the cutting tool comprising a shaft;
• and one or more cutter disks adjacent to one end of the shaft and extending laterally from the shaft;
• an anchor comprising a shaft;
• a head adjacent to one end of the shaft and extending laterally from the shaft;
• a sleeve axially surrounding the shaft;
• an adjustable clamp juxtaposed to the sleeve for moving the sleeve along the longitudinal axis of the shaft;
• and a deformable plate positioned on the shaft between the head and the sleeve, wherein the deformable plate is capable of movement between a first position wherein the plate is substantially confined to an area within the perimeter of the head and a second position wherein the plate is perpendicular to the shaft and substantially uniplanar with the perimeter of the plate extending at least partially beyond the circumference of the borehole and into the undercut region, and wherein movement of the sleeve along the shaft towards the head moves the deformable plate between the first and second positions;
• and
• a set of instructions for use.
