Mark J Posted August 12, 2017 Report Share Posted August 12, 2017 I've heard one can touch up the replaceble carbide tips of turning tools on a 1000 grit diamond stone, prolonging the time between replacements.. Does anyone here have any experience with or insite on this idea? Corollary question. How much "mileage" do you get out of your carbide tips.

Popular Post gee-dub Posted August 12, 2017 Popular Post Report Share Posted August 12, 2017 Wet dry paper on a hard flat surface. Place the face of the cutter on the paper. Put your finger on the back of the cutter. The hole acts as a grip. Draw circles or figure eights for a while. I sometimes wet the paper with mineral spirits. As to length of useful life, I am still using the originals. 3 Quote Link to comment Share on other sites More sharing options...
Barron Posted August 12, 2017 Report Share Posted August 12, 2017 I use a small diamond stone that has 300 on one side and 1000 on the other. I use a little window cleaner for lubricant and work the tip just like gee-dub described. Just the 1000 side. Works great. I suppose it will reach a point where it will need to be replaced, but I haven't found it yet. How long before sharpening varies with the wood I am turning, but really, once I learned you can sharpen the little things I don't let them get very dull. 2 Quote Link to comment Share on other sites More sharing options...
Mark J Posted August 13, 2017 Author Report Share Posted August 13, 2017 Thanks guys. Follow on question. Since carbide is harder any clue as to how much more time on the abrasive it takes as compared to say a chisel? Quote Link to comment Share on other sites More sharing options...

I use these for sharpening my carbide: http://www.rockler.com/diamond-hone-sharpening-set I take about 10 gentle swipes on each grit and they are ready. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Barron Posted August 13, 2017 Popular Post Report Share Posted August 13, 2017 I mark each edge with a sharpie as I rotate the cutter. When sharpening, I just rub until the sharpie marks are gone. I do the same thing when re-grinding my traditional tools. 3 Quote Link to comment Share on other sites More sharing options...
Jplupercio@CSUSA Posted August 18, 2017 Report Share Posted August 18, 2017 Here's a really good video that show the way to sharpen them and tells you what you need to get started. 1 Quote Link to comment Share on other sites More sharing options...
Guest Randy Posted August 25, 2017 Report Share Posted August 25, 2017 How many circles or how long you spend on the stone depends, I suppose, on how often you run them over the stone. I found that the cutter only needs maybe 5 - 10 circles on a diamond stone to make them sharp again. It makes a huge difference in the cutting ability and gives a much better surface than when the edges are dulled. Quote Link to comment Share on other sites More sharing options...
