A control arrangement for an electro-mechanical tool is disclosed. The tool may, for example, be a nailer or stapler, and is provided with an impact member which is frictionally moved in a working stroke by means of an electrically driven flywheel, which presses the impact member against the support element, which may be a counter-rotating flywheel. A solenoid is provided to move the impact member into the bite between the flywheel and support element. A trigger actuated switch and a safety switch actuated by contact of the tool with the workpiece must b...
An electric impact tool comprising an impact member, a manually actuated control means, a work responsive control means, an electric motor driven flywheel and a support element, said flywheel and said support element being positionable with respect to each other by a distance less than the thickness of said impact member, and a solenoid responsive to actuation of both said manually actuated and said work responsive control means, for introducing the impact member between the flywheel and support element when spaced from each other by a distance less than...
