Norton 57A Triangular File
Features and benefits
India, our smooth cutting aluminum oxide abrasive produces a strong, keen, long-lasting edge and is the choice for the best blend of cut rate and finish
Used for 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
Coarse grit quickly restores worn edges; medium grit produces the average edge needed for most tools; and fine grit produces an even sharper edge
Designed to retain their shape while imparting a uniform finish
