The Norton India AO triangular files are specifically designed for diverse applications such as deburring, chamfering and radiusing. They are also suitable for cleaning tap threads, stoning the cutting surfaces of milling cutters and lapping honing tools, dies and molds. Additionally, they are effective for creating precision points on center punches. The coarse grit file is ideal for quickly repairing worn edges, the medium grit file is optimal for producing standard edges and the fine grit file delivers the sharpest edges. Constructed from aluminum oxide abrasive, each file is engineered for durability, enabling the achievement of sharp edges and a consistent finish. Utilized for diverse deburring, chamfering and radiusing tasks, including tap thread cleaning, milling cutter surface stoning, honing tool lapping, die and mold finishing and precision center punch pointing Coarse grit rapidly restores worn edges, medium grit achieves the standard edge required for most tools and fine grit creates an even sharper edge Engineered to maintain their form while providing a consistent finish The aluminum oxide abrasive from India delivers a smooth cutting performance, producing a robust, sharp and durable edge It is the preferred choice for achieving an optimal balance between cutting speed and surface finish
