Engineering File is a tape saw file that is designed specifically for sharpening a metallic tool. It is basically used to remove the fine amount of material from the workpiece. It is extensively used in the metalworking and woodworking. The tool is made out of the high-grade case hardened steel bar. We have made available it in a square, triangular and round cross-section. It cuts the material if pushed over the workpiece. It has forward-facing cutting-teeth and therefore, one should not push the Engineering File directly backward as this can dull the teeth.
