Abstract: To remove, by suction, chips and debris arising in operation of a hand-cutting tool, for example a sheet-metal nibbling tool, a saber saw, or the like, an ejection nozzle is surrounded by a preferably plastic body defining, internally a Venturi, and externally of the ejection nozzle a vacuum, underpressure or suction chamber which is connected through a preferably flexible hose to a suction pick-up nozzle, removably attached adjacent a reciprocating tool at the working or cutting head of the tool. The suction pick-up nozzle preferably includes a chamber in direct air communication with the tool so that chips which arise in tool operation are directly drawn into the pick-up nozzle for removal, by air flow suction, through the suction duct and to a collecting and disposal hose.
