Our diamond needle files can be used either wet or dry, they will last longer when used wet but it is understood that this isn't always practical when working on a delicate watch or clock part. As with all our products allow the tool to do the work and do not apply too much pressure especially if working on a corner or sharp edge.

The many uses for our diamond files:

  • Use the tip for detailed areas such as ring shanks
  • Removing excess solder
  • Shaping precious stones for jewellery
  • Sharpening carbide cutting tools
  • Enlarging holes
  • Fitting clock and watch glasses
  • Refacing clock & pallets
  • Re-pivoting clock and watches
  • Beveling cut crystal glasses
  • Sharpening household objects
  • Cross graining burnishing tools
  • Sharpening fishing hooks
  • Musical instrument making


Diamond grit is precisely electroplated onto a steel blank with a rubber handle

  • Overall length: 140mm
  • Shaft: 2mm
  • Diamond length: 50mm
  • Handle diameter: 3mm
