<p>An undercut anchor system designed for effecting a drill hole and enlarging a lowermost end thereof for insertion and setting of an anchor therein, which utilizes interlocked components surrounding a rod body which can be used as a setting tool in a one-step process to position a bore hole sleeve and an anchor in position within the bore hole. An anchor is positioned on the rod body below the bore sleeve. A cutting tip protrudes from a lower end of the rod body. The cutting tip portion has an operational cutting radius greater than a radius of the rod body. In this manner, an anchor can be inserted within the pre- drilled hole, and, when the anchor has been flanged outwardly by conventional means within the hole, the flange portions of the anchor will rest within the enlarged area, thus securely retaining the anchor in place.</p> |
