I am tooling up to sharpen circular saw blades, besides purchasing a good power machine I wanted to purchase some quality diamond files for touch-up and perhaps even sharpening the entire blade, I use diamond files/stones/wheels all the time for other tasks, so I was surprised I couldn't find much in the way of good files.

Is anyone using diamond files for working on their circular blades? I haven't found much information on the use of diamond files for circular saws, so I wanted to see if others here were using them.

Thanks sunaj

    I'm voting to close this question as off-topic because it requests purchasing recommendations/brand recommendations – rob Apr 30 '17 at 18:34
  • Welcome to Woodworking.SE! Unfortunately, purchasing recommendations are off-topic for this site, but if you remove the part inquiring about what brand of files, we will be happy to reopen. – rob Apr 30 '17 at 18:36

    Diamond files wouldn't normally be used for this kind of work because they're A) a little coarse and B) not available in known grit numbers (at least not that I've seen). It's more common to use small versions of the diamond honing plates instead, often what are called paddles because they have a long plastic base with the diamond plate mounted at one end. However, there's no reason you can't use a full-size diamond plate for sharpening circular saw blades, a bit cumbersome perhaps but the extra width or length shouldn't get in the way. – Graphus May 1 '17 at 7:22
  • @rob: This really shouldn't be voted to close. He is both asking if this is a best known methods and if so asking for which particular file would work best. – jbord39 May 1 '17 at 18:45

Mattias Wandel from Woodgears.ca has a good method for sharpening circular saw blades with a diamond disc in a drill/dremel. He goes a lot more in depth and builds a jig to do this, but you could do the same thing by hand with a little less precision.
