FAQ

How is a diamond file different from an ordinary steel file?

A diamond file is coated with diamond grit, which is harder than almost any material, so it can file hard work such as carbide, glass, and hardened steel — things a steel file cannot. But a diamond file is not for soft or mild steel, because soft chips clog the teeth and dull the cutting action.

Can I use it on soft materials?

Not recommended — mild steel or soft material clogs the diamond teeth and dulls the file quickly. Use diamond files only on hard materials, clean along the teeth with a wire brush, and never knock the file against a bench.

How do I care for a diamond file?

Keep it free of oil (oil makes it slip and stop cutting), prevent rust, store it apart from other tools, and wrap it in corrugated paper so edges don't knock together. Clean along the teeth with a brass wire brush to keep it sharp and long-lasting.
