How to use our Medium Diamond Needle Files

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 don't 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


Diamond 600 grit is precisely electroplated onto a steel blank with a plastic handle

  • Overall length: 140mm
  • Shaft: 3mm
  • Diamond length: 70mm
  • Handle diameter: 4mm

Customer Reviews

Good file but the handle is too small to be ideal for large hands.

I’d like to cut and smooth some tungsten carbide , will these discs do the job?


The diamond slitting discs would be perfect for the cutting of your carbide.  To smooth, try our 600 grit diamond files. To polish the tungsten carbide you can use our diamond grinding paste. I hope this helps!
