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 small 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
"I have some beautiful cut glass wine glasses with minor chips in them so I bought a half round diamond file in 900 grit as recommended in the tutorial. We tried the file on the glass and a bone china mug - it works brilliantly. Compliments are due to you on fantastic service and advice" - Maureen Scurr"
"I have used my diamond files in a number of ways. Re-facing clock pallets the different shaped diamond files allow you to get in where it would be difficult to reach with a grindstone. Fitting clock and watch glasses ease it by running a diamond file gently round the edge. Drilling holes in barometer glass to fit centre hand I sometimes ease the hole using a round diamond file. Repivotting in a clock I use a diamond file to rough up a piece of blued steel prior to fitting in the hole. When turning blued steel you can form a glazed surface which is not easy to cut through with a graver. I cut through it with a diamond file" - Clive Driscoll
"These Diamond Files are my favourite tools because of the large amount of pivot work I do. I can't imagine getting along without these. I can't imagine getting along without my diamond grinding wheel either. Good news is I don't have to do without either!" - Robert Uhrich
