Use the triangular file to eliminate flash and chamfer and to notch nail-type or one-piece axles, and then progressively polish with 7 grades of polishing paper - 700 to 2000 grit. Kit includes magnifier to monitor your polishing progress. For a final finish equivalent to an 8,000-grit polish, follow up with the Diamond Finishing Kit
