The method and apparatus for drilling holes and optionally inserting fasteners of the present invention provide for efficiently drilling holes through a multiple-layer structure because the layers are securely held together during the drilling by an electromagnet and a clamp, each on opposite sides
The method and apparatus for drilling holes and optionally inserting fasteners of the present invention provide for efficiently drilling holes through a multiple-layer structure because the layers are securely held together during the drilling by an electromagnet and a clamp, each on opposite sides of the structure. The electromagnet and clamp hold the layers together so tightly that burrs do not form within the holes and debris does not accumulate between the layers and, therefore the layers do not have to be disassembled after drilling. In addition, the apparatus and method of the present invention provide for initially drilling the hole with a countersink and for inserting a fastener into the hole, through the electromagnet, immediately after drilling the hole, such that the hole does not have to be revisited after reassembly and drying of the sealant in order to drill a countersink and/or insert a fastener.

1. An apparatus for drilling a hole in a structure, comprising:an electromagnet defining an opening sized to receive a drilling tool, wherein said electromagnet comprises a first guidepiece aligned with and at least partially defining the opening defined by said electromagnet, and wherein said electromagnet further comprises a second guidepiece positioned opposite the first guidepiece, wherein the second guidepiece is also aligned with and at least partially defines the opening defined by said electromagnet; and a clamp aligned with the electromagnet on the opposite side of the structure, said clamp comprised of an at least partially magnetic material such that said electromagnet and said clamp are capable of holding the structure together. 2. An apparatus for drilling a hole in a structure, comprising:an electromagnet defining an opening sized to receive a drilling tool, wherein said electromagnet comprises a plurality of revolutions of wire and a plurality of spacers located between the revolutions to facilitate cooling the wire; and a clamp aligned with the electromagnet on the opposite side of the structure, said clamp comprised of an at least partially magnetic material such that said electromagnet and said clamp are capable of holding the structure together. 3. An apparatus for drilling a hole in a structure, comprising:an electromagnet defining an opening sized to receive a drilling tool; a clamp aligned with the electromagnet on the opposite side of the structure, said clamp comprised of an at least partially magnetic material such that said electromagnet and said clamp are capable of holding the structure together; and a platform capable of being positioned proximate said electromagnet, wherein said platform defines a first opening that is aligned with the opening defined by said electromagnet. 4. The apparatus of claim 3, wherein said platform comprises a guidepiece aligned with and at least partially defining at least a portion of the first opening defined by said platform.5. The apparatus of claim 4, wherein the portion of the first opening defined by the guidepiece is smaller than other portions of the first opening defined by said platform.6. The apparatus of claim 3, wherein said platform defines a passageway having one end proximate the first opening such that debris is pulled through the passageway while drilling a hole in the structure.7. The apparatus of claim 3, further comprising a rail mounted to the structure and adapted to carry said platform for movement relative to the structure.8. An apparatus for drilling a hole in a structure, comprising:an electromagnet defining an opening sized to receive a drilling tool; and a clamp aligned with the electromagnet on the opposite side of the structure, said clamp comprised of an at least partially magnetic material such that said electromagnet and said clamp are capable of holding the structure together, wherein said clamp is shaped to receive and slidably attach to a portion of the structure such that said clamp is slidably mounted to the structure. 9.
