1. Field of the Invention
The present invention relates to drill bit devices and more particularly pertains to a new drill bit device for aiding a person in the removal of mortar positioned around bricks and stones.
2. Description of the Prior Art
The use of drill bit devices is known in the prior art. U.S. Pat. No. 3,709,308 describes a diamond drill bit device for use in a plurality of drilling situations and in particular for mining purposes. Another type of drill bit device is shown in U.S. Pat. No. 5,592,996. Yet another drill bit is found in U.S. Pat. Des. No. 390,239.
While these devices fulfill their respective, particular objectives and requirements, the need remains for one or more drill bits that are configured for removing mortar from between bricks and stones.
The present invention meets the needs presented above by generally comprising a toothed drill bit that includes an elongated rod that has a first end and a second end. A plurality of rectangular plates is attached to and extends laterally from the rod. Each of the plates has a distal edge with respect to the rod. Each of the distal edges is orientated parallel to a longitudinal axis of the rod. The first end of the rod is removably extendable into and attached to a drill.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A bladed drill bit 30 includes a solid shaft 32 that has a first end 34 and a second end 36. The second end 36 of the shaft 32 has a pointed tip attached thereto that is again preferably comprised of a carbide material. A plurality of blades 38 is attached to the shaft 32. Each of the blades 38 extends from the second end 36 and toward the first end 34. The blades 38 each curl partially around the shaft 32 and have a helical shape. Each of the blades 38 has an outer edge 40 with respect to the shaft 32. The outer edge 40 is pointed. The plurality of blades 38 includes two blades positioned opposite with respect to each other on the shaft. The first end 34 of the shaft is removably extendable into and attached to a drill 8. Each of the plates 22 and the blades 38 include a plurality of diamond portions 40 embedded therein to provide additional cutting strength to the blades 38 and plates 22.
In use, each of the drill bits 12, 30 is used for removing mortar 50 from around stones and bricks 52. The pointed ends 20, 38 are extended into the mortar 50 and the drill bits 12, 30 are then moved along the mortar 50 as shown in
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
