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.

Description

[0001] This application is a divisional of U.S. application Ser. No. 10 / 988,998 filed Nov. 12, 2004, which claims priority pursuant to 35 U.S.C. 119(e) to co-pending U.S. Provisional Patent Application Ser. No. 60 / 519,223, filed Nov. 12, 2003, the entire disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates generally to systems, apparatuses and methods for anchoring. More particularly, the present invention is concerned with a two-stage drill bit and a method for anchoring into brittle materials such as concrete, stone, masonry and cementuous materials using a common nail. BACKGROUND OF THE INVENTION [0003] In construction applications it is often necessary or desirable to anchor into an existing concrete structure. In many construction applications the anchor is intended to be permanent to tie in a newer structure with an existing concrete structure. In such permanent anchoring applications, removal of the anchors is g...
