Patent ID: 7384223

Claim:
An anchoring system including a drill bit for making a hole for an anchor and an anchor, the drill bit comprising: a first cutter including a first diameter sized to provide frictional contact between a generally fixed outer diameter of a shank of the anchor and a circumference of a hole made by said first cutter; and a second cutter spaced apart from said first cutter, said second cutter including a second diameter greater than said first diameter sized to provide a relief between the shank of the anchor and a circumference of a hole made by said second cutter, wherein said second diameter is generally less than a head diameter of the anchor, the head diameter of the anchor being greater than the shank diameter; a depth gage spaced apart from said second cutter opposite said first cutter; wherein a length between said depth gage and said first cutter is equal to or greater than a length of the anchor, wherein the length is approximately 3.75 inches and wherein a length between said depth gage and said second cutter is greater than a thickness of a material that is to be anchored to another material by the anchor and at least greater than one half said length between said depth gage and said first cutter, wherein the length is approximately 2.375 inches; and wherein the anchor comprises a 16 duplex or a 16 common nail including a shank diameter of approximately 0.166 inches, wherein said first diameter of said cutter is approximately 0.156 inches, and wherein said second diameter of said cutter is approximately 0.170 inches such that the frictional contact between the shank of the anchor and the circumference of the hole made by said first cutter is provided without any intermediate anchoring materials between the shank of the nail and the circumference of the hole.
