Abstract
Abstract A tool is disclosed for both drilling a hole and thereafter securing a screw anchor therein in a quick and expeditious manner. The tool comprises a handle with a threaded stem extending therefrom. The threaded stem allows a screw anchor and a hard plastic drill tip to be threadably mounted thereon. The tool facilates the manual application of sufficient drilling pressure to the thus mounted drill tip so as to form the appropriately sized hole for the screw anchor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A tool for preparing a hole in a wall for receipt of a screw anchor that is to be secured to the wall by the same tool, said tool comprising: a handle with a threaded stem extending therefrom, said threaded stem having a length sufficient to allow a screw anchor to be threadably mounted thereon whereby at least two threads of the threaded stem are exposed beyond the end of the thus mounted screw anchor; and an integrally formed drill tip having a point and a tapered drilling length extending back from said point, said integrally formed drill tip furthermore having a tapped hole extending along the central axis of the drill tip, said tapped hole having threads therein which match the exposed threads on said threaded stem, said tapped hole furthermore being of sufficient depth so as to allow said drill tip to abut the end of a screw anchor threadably mounted on said threaded stem when said drill tip is threaded onto the exposed threads of said threaded stem, the abutment only being maintained when the drill tip is rotated in a drilling direction so as to drill a hole into a wall structure so as to form a hole for the screw anchor.
Claim 2
Dependent Claim
206 words
A tool for preparing a hole in a wall for receipt of a screw anchor that is to be secured to the wall by the same tool, said tool comprising: a handle with a threaded stem extending therefrom, said threaded stem having a length sufficient to allow a screw anchor to be threadably mounted thereon whereby at least two threads of the threaded stem are exposed beyond the end of the thus mounted screw anchor; and an integrally formed drill tip having a point and a tapered drilling length extending back from said point, said integrally formed drill tip furthermore having a tapped hole extending along the central axis of the drill tip, said tapped hole having threads therein which match the exposed threads on said threaded stem, said tapped hole furthermore being of sufficient depth so as to allow said drill tip to abut the end of a screw anchor threadably mounted on said threaded stem when said drill tip is threaded onto the exposed threads of said threaded stem, the abutment only being maintained when the drill tip is rotated in a drilling direction so as to drill a hole into a wall structure so as to form a hole for the screw anchor.
Claim 3
Dependent Claim
61 words
The tool of claim 1 wherein said drill tip further comprises: a cylindrical portion extending rearwardly of said drilling length, said cylindrical portion having a sufficient diameter so as to substantially abut the end of a screw anchor threadably mounted on said threaded stem and to thereby allow sufficient torque to be transmitted to the drilling length of said drill tip.
Claim 4
Dependent Claim
30 words
The tool of claim 2 wherein the outside diameter of said cylindrical portion of said drill tip is substantially equal to the largest outside diameter of the mounted screw anchor.
Claim 5
Dependent Claim
24 words
The tool of claim 1 wherein said drill tip is fabricated from a hard plastic having a sufficient hardness to drill through wallboard material.
Claim 6
Dependent Claim
30 words
The tool of claim 1 wherein said handle has a contour which facilitates the grasping thereof in a manner which allows sufficient drilling pressure to be applied to the wallboard.
