Abstract
A combination tool for edging and polishing the edge of eyeglass lenses comprises an axially extending rotatable cutter body having first and second peripherally disposed and axially extending cutter portions. Each cutter portion has a first notch therein for shaping an edge of a lens. The first notches are equiaxially spaced along the body. An axially extending polishing tool is secured to the body and is rotatable therewith. The tool has a second notch formed therein for shaping an edge of a lens. An abrasive coating is applied to the polishing tool for polishing the lens edge.
