How to use

Secure the workpiece to prevent movement before filing. Hold the file by the handle with a steady forward stroke, applying even pressure on the push stroke and lifting on the return if the file is single-cut; follow the file’s tooth direction to maintain cutting efficiency. Use smooth, controlled passes and check progress frequently to avoid removing too much material. For deburring, use lighter strokes and finish with finer movements to obtain the required edge quality. Clean metal filings from the teeth periodically to preserve cutting performance.

Usage recommendations

Use with a suitable handle for safe grip and better control. Match stroke length and pressure to the material and the required finish. For hardened steels or precision finishes, consider progressive filing with finer files or abrasive stones to achieve the desired surface quality.
