ABSTRACT:
A disc sander, grinder, or combination machine, hand-held, having an umbrella-shaped hood enclosing the full perimeter of the disc and urged downward to contact the workpiece so air and debris particles may be drawn by a suction blower through an annulus surrounding the disc and discharged into a porous bag for collecting of debris.
Making the porous bag of wire mesh for strength and heat resistance, and making the grinding disc working surface a flat cone to help ensure better collection of debris particles are additional features.
