Unique drive geometry results in interrupted contact of the abrasive to the work surface. Since the Piaf is always changing plane, the abrasive does not "load-up", and heat generation is minimized. The result is a scratch-free finish, longer abrasive life, and the virtual elimination of hand sanding. Extra muffling and a tough polypropylene motor cover that provides a comfortable hand hold. The DAQ meets all current OSHA noise level requirements Maximum no-load speed: 10,000 RPM. Applications include: sanding filler; removal of old paint, rust and scale; shaping; forming; feather edging.
