The Norton India AO Triangular Files are ideal for use in a variety of deburring, chamfering and radiusing applications, including cleaning tap threads; stoning cutting surfaces of milling cutters; lapping honing tools, dies and molds; and putting precision points on center punches. The coarse grit file is used to quickly repair worn out edges; the medium grit is best for producing the average edge, and the sharpest edge is delivered with the fine grit file. Each file is built to last and is made of an aluminum oxide abrasive, allowing you to achieve sharp edges and a uniform finish.
