ABSTRACT:
A cutting tool is provided for removing the exposed pintail of a set fastener, such as blind fastener of the type commonly used in the aerospace industry. The tool comprises an air motor for rapidly rotating a relatively thin cutting disk made from a highly abrasive material. The tool is provided with an adjustment mechanism to control the distance of the cutting disk with respect to the surface in which the fastener is set. In operation, the cutting disk rapidly cuts through and removes the pintail so that it is substantially flush with the surrounding surface. A vacuum system also is provided inside the tool for collecting the severed pintails and related debris that results from the pintail cutting process.
