Title:
APPARATUS AND METHOD FOR DRILLING HOLES AND OPTIONALLY INSERTING FASTENERS
Document Type and Number:
WIPO Patent Application WO2003101652
Kind Code:
A3
Abstract:
The method and apparatus for drilling holes and optionally inserting fasteners (80) of the present invention provide for efficiently drilling holes (76) through a multiple-layer structure (18) because the layers are securely held together during the drilling by an electromagnet (10) and a clamp (12), each on opposite sides of the structure (18). The electromagnet (10) and clamp (12) hold the layers together so tightly that burrs do not form within the holes (76) and debris (70) 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 (76) with a countersink and for inserting a fastener (80) into the hole (70), through the electromagnet (10), immediately after drilling the hole (76).
