DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0028] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0029] As noted above, there is a long-felt need in the art for an improved drill head that can be attached to any air-powered tool. There is also a long-felt need in the art for a drill head that can convert any pneumatic tool to a drilling device. Additionally, there is a long-felt need in the art for a drill head that can accommodate different drill bits. Moreover, there is a long-felt need in the art for a drill head that is easily attached to and removed from an air tool. Further, there is a long-felt need in the art for a drill head design that can be used as an alternative to larger bulky drills for more fine-tuned use. Furthermore, there is a long-felt need in the art for an improved drill head that can be rotated at any speed using drive gear of the air-powered tool. Finally, there is a long-felt need in the art for a drill head that is compatible with air-powered tools and can be used for drilling in hard-to-reach areas easily.

[0030] The present invention, in one exemplary embodiment, is a novel detachable drill head for an air-powered tool. The drill head comprising a coupling portion for securely coupling to an air-powered tool, the coupling portion including a plurality of locking pins and ribs for secure coupling and a female port for receiving drive from the air-powered tool, a rotatable shaft for rotating using the received drive force, wherein a drill bit attached to a chuck portion of the air-powered tool is rotated using the rotatable shaft. The drill head comes in different shapes and sizes and can be attached to any air-powered tool.

[0031] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one potential embodiment of the novel drill head 100 of the present invention in accordance with the disclosed architecture. The drill head 100 is configured to attach to any air-powered tool easily and quickly for enabling fast and easy drilling. Further, the drill head 100 is configured to accommodate different drill bits that are interchangeably attached to the drill head 100 allowing users to perform a well-balanced drill in hard-to-reach and/or confined areas.

[0032] More specifically, the drill head 100 is a compact tool for manipulation in small spaces and can be easily operated using any conventional air-powered tool. The drill head 100 has a coupling portion 102 for coupling to an air-powered tool and for receiving power from drive gear of the air-powered tool like air ratchet. The coupling portion 102 has an inner surface having a plurality of grooves disposed thereon (shown in FIG. 2) that helps in coupling the drill head 100 to the air-powered tool. A drill chuck 104 is positioned at one end of the coupling portion 102 and includes jaws 106 for holding a drill bit 112 or any other cutting instrument. The jaws 106 can secure drill bits 112, drive bits, and/or die grinder mounting bits having round shanks or hex sided shanks. The chuck 104 is connected to the drill head housing 108 wherein the housing 108 rotatably drives using the gear drive of the air-powered tool to which the drill head 100 is mounted. The rotating portion 110 of the drill head 100 is configured to rotate using the drive of the air-powered tool to which the coupling portion 102 is removably attached.

[0033] FIG. 2 illustrates an enlarged view of the coupling portion 102 of the drill head 100 for coupling to an air-powered tool in accordance with the disclosed architecture. As illustrated, the coupling portion 102 has a female port 202 which engages to a male port of the air-powered tool. The female port 202 is aligned with the male port when the drill head is coupled to the air-powered tool in order to transfer drive force or power from the motor of the air-powered tool to the drill head 100 and to the output of the drill head 100.

[0034] A plurality of locking pins 204 are positioned on the coupling portion 102 for locking the drill head 100 to the air-powered device. A base plate 206 helps in abutting the drill head 100 to the air-powered tool and helps in secure positioning of the head 100. A plurality of recesses 208 and ribs 210 also help in secure coupling and positioning of the head on the air-powered tool.

[0035] FIG. 3 illustrates an enlarged view of an exemplary coupling portion of a conventional air-powered tool to which the drill head of the present invention can be attached for use in accordance with the disclosed architecture. The coupling portion 302 of an air-powered tool has a male coupler or port 304 which is aligned with the female port 202 of the head 100 of the present invention for transferring power to the head 100. While the exemplary embodiments show that the air-powered tool has a male coupler 304 and the drill head has female coupler 202, it is to be appreciated that these could be reversed. The plate 206 of the head 100 abuts to the front face 306 of the coupling portion 302 thereby aligning the male coupler or port 304 and the female port 202. A plurality of grooves 308 are positioned in the coupling portion 302 allowing the locking pins 204 of the head 100 to lock with the air-powered tool. The female port 202 includes a graduated female coupler that decreases in diameter from a first diameter of ¾″, to a second diameter of ½″, and finally to a third diameter of ¼″ for selectively receiving respective sized ratchet male drive heads.

[0036] The locking pin receivers 308 are used to receive the locking pins of the drill head 100 and are used for secure coupling. It should be appreciated that the base plate 206 of the head 100 and the front face 306 of the coupling portion 302 can be magnetic, thereby obviating the need for screws to attach the drill head to the air-powered tool.

[0037] FIG. 4A illustrates a perspective view showing another embodiment of the drill head of the present invention in accordance with the disclosed architecture. In the present embodiment, the drill head attachment 400 is designed to allow drilling in smaller areas, confined angles and narrow spaces. More specifically, the drill head 400 has a chuck component 402 and a longitudinal handle 404 positioned perpendicular to the chuck component 402. The coupling portion 406 is used for attaching the drill head 400 to any air-powered tool. Further, the drill bit 408 is detachable and can be interchanged with any bit of different design and size.

[0038] FIG. 4B illustrates a perspective view showing yet another embodiment of the drill head of the present invention in accordance with the disclosed architecture. In the present embodiment, the drill head attachment 410 is designed to attach drill bits of higher strength. The attachment 410 includes a chuck component 412 attached to a drill bit jaw 414. The rotating component of the attachment 410 is positioned inside the housing 416 at one end and a coupling portion 418 is positioned on an opposing end for securing the attachment 410 to any air-powered tool.

[0039] FIG. 5 illustrates a perspective view of the drill head 100 attached to an air ratchet and used for drilling in accordance with the disclosed architecture. The drill head 100 is coupled to an air-powered tool, such as an air ratchet 500, using the coupling portion having the female port of the drill head. Once the drill head 100 is securely coupled, then, a desired drill bit 502 is attached to the chuck portion 104 and next, using the gear drive of the air ratchet 500, the drill bit 502 is rotated to perform drilling, assembling, or any other desired task.

[0040] Other shapes, designs, and configurations of the drill head attachment 100 are contemplated and fall within the scope of the invention without affecting the utility of the device.
