Abstract
An improved tool for grinding a ridge in a bore comprises a planar base plate which is positioned over the bore, a handle along one edge of the base plate and a cutter tool projecting from the plate on the other extreme or diameter of the plate. The cutter tool cooperates with a rotary driven tool to provide a cutting action against the peripheral ridge in a cylinder bore, for example.
