How To Use Our Diamond Needle Files

Our diamond needle files are versatile and can be used wet or dry. While they last longer when used wet, we understand that using them wet may not always be practical when working on delicate watch or clock parts. 

It's important to let the file do the work and not apply too much pressure, especially when working on sharp edges or corners.

Here are some of the many ways our diamond files can be used:

  • Reamer for opening and enlarging holes
  • Use the tip for detailed work such as ring shanks
  • Removing excess solder
  • Shaping precious stones for jewellery making
  • Sharpen carbide cutting tools
  • Fit clock and watch glasses
  • Refacing clock & pallets
  • Re-pivoting clock and watches
  • Bevel cut crystal glasses
  • Sharpening household objects
  • Cross-grain burnishing tools
  • Sharpen fishing hooks


Diamond 600 grit is precisely and uniformly electroplated onto a steel blank with a green rubber handle
