Abstract
Accessories for an angle grinder include a tool comprising a rotary disk having releasably attached to its surface, an annular attachment having a cutting or abrading, (“shaping”), surface, and rest means in a rest zone for supporting the grinder on a surface to be shaped. The rest means may be a non-rotating nose beneath the grinder; a rubbing contact mounted on a flat tool or simply part of the surface of a convex tool. Tilting the grinder about the rest means gives effective control of the tool. Steeper tilts cause the cutting or abrading surface to bite more deeply into the surface to be shaped. The grinder is preferably stroked toward the user with the cutting or abrading zone trailing. Most disks are perforated. Work to be shaped can be seen through the spinning disk during use. The annular attachment can have a variety of cutting or abrading surfaces.
