Anchoring drill bit, system and method of anchoring

Abstract

A system, apparatuses and methods for anchoring are provided. The system includes two-stage drill bit and a method of anchoring into a two-stage hole drilled by the drill bit. The apparatus of the instant invention includes a two-stage drill bit for drilling a pilot hole for a common nail into a material such as concrete, stone, masonry or cementuous or other materials. The method of the instant invention includes the steps of drilling a first hole within a material to which an object is to be anchored, drilling a second hole concentric with the first hole, and placing an anchor within the holes.

1 . A method of anchoring comprising the steps of: 
 cutting a hole including a first diameter in a material to a first depth;    cutting a hole including a second diameter generally concentric with the first diameter hole in the material to a second depth; and    positioning a nail shank into the first and the second diameter holes.    
   
   
       2 . The method as claimed in  claim 1  further comprising the step of driving the nail through an object to be anchored to the material prior to said step of positioning the nail shank.  
   
   
       3 . The method as claimed in  claim 2  wherein said step of driving the nail through the object includes the step of inserting the nail shank through a pre-drilled hole in the object.  
   
   
       4 . The method as claimed in  claim 3  wherein the pre-drilled hole in the object is made during said steps of cutting the first and second diameter holes in the material.  
   
   
       5 . The method as claimed in  claim 1  wherein the first diameter is less than the second diameter.  
   
   
       6 . The method as claimed in  claim 5  wherein the first diameter is less than or equal to a diameter of the nail shank.  
   
   
       7 . The method as claimed in  claim 5  wherein the second diameter is greater than a diameter of the nail shank.  
   
   
       8 . The method as claimed in  claim 1  wherein the first depth is greater than or equal to a length of the nail shank.  
   
   
       9 . The method as claimed in  claim 1  wherein the second depth is less than the length of the nail shank.  
   
   
       10 . The method as claimed in  claim 1  wherein said steps of cutting first and second diameter holes are performed by a single two-stage drill bit.  
   
   
       11 . A method of removably anchoring comprising the steps of: 
 cutting a hole including a first diameter in a material to a first depth, the first diameter being generally less than or equal to a diameter of an anchor;    cutting a hole including a second diameter generally concentric with the first diameter hole in the material to a second depth, the second diameter being generally greater than the diameter of the anchor;    positioning an anchor into the first and the second diameter holes such that the anchor is in frictional engagement with the material at a circumference of the first diameter hole; and    removing the anchor from the first and second diameter holes when the anchor is no longer needed.
