Protective guard unit for metal working tool

摘要

A hand held cutting tool is disclosed for use in cutting articles, especially when the tool is to be used in confined quarters while protecting the operator from being cut by the tool. The tool includes a motor which drives the cutter only when one hand of the operator grasps the motor housing and closes a trigger. Portions of a cutter and cutter guard project out of a small housing, and the guard normally encompasses the projecting portion of the cutter. When it is desired to expose the projecting portion of the cutter to perform a cutting operation, the other hand of the operator must grip a portion of the tool remote from the exposed portion of the cutter and must actuate a valve or handle to expose and maintain the guard in the exposed cutting position.
