Compatible Materials

Compatible Materials & Applications

Materials:

  • Hardened Metal, Steel, and Alloys
  • Glass, Mirrors, and Ceramics
  • Marble, Stone, and Hardwoods
  • Jewelry Metals (Gold, Silver, Platinum)

Tool Types:

  • Manual hand tools used for finishing work after using Dremel or Milwaukee rotary tools.
  • Ideal for fine-tuning parts used in Watchmaking, Model Building, and Die Cast Molding.

How To Use

  1. Selection: Choose the profile (hook, square, etc.) that best fits the contour of your workpiece.
  2. Technique: Use light, steady pressure. Diamond files grind material rather than "cut" it; let the 150-grit diamonds do the work.
  3. Stroke: Use a consistent pull-stroke or light "push-pull" motion for detail work.
  4. Maintenance: Periodically clean the file with a soft brush or water to clear away dust and maintain grinding efficiency.

Expert Tip: For high-detail glass or ceramic work, using a drop of water on the filing surface will keep the tool cool and trap fine dust for a cleaner workspace.

Use Cases

Home Restoration: Smoothing chipped glass edges, fixing cracked tiles, or restoring antique mirrors.

F.A.Q.

Q: Can these files be used on hardened steel?
A: Yes. The 150-grit diamond coating is specifically engineered to file materials that standard steel files cannot touch, including hardened steel, glass, and ceramics.

Q: What is the benefit of the curved "riffler" shape?A: The bent ends are designed for "riffling"—reaching into concave areas, deep grooves, and intricate carvings that a straight needle file simply cannot access.

Q: Will these work for jewelry and watch repair?
A: Absolutely. They are a staple for jewelers and watchmakers for deburring findings, reshaping watch cases, and cleaning up die-cast molds.
