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 01 '17 at 07:22
  • @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 01 '17 at 18:45
  • Ok I edited it as requested – sunaj May 01 '17 at 19:22
  • @jbord39 The first part is definitely on-topic, but we try to avoid brand recommendations for various reasons, not the least of which are that they can often be opinion-based, solicit "me too" answers, and have integrity implications for the site. – rob May 01 '17 at 21:05
  • @rob: sometimes using a brand is opinion based (both products on par with equality or some pro's/con's for each). sometimes it is not (just a crappy product). – jbord39 May 02 '17 at 04:47
  • @jbord39 we are in agreement on that point. That said, as a blanket policy, brand recommendations are off-topic for the site as outlined in https://woodworking.stackexchange.com/help/on-topic and for the other reasons I mentioned above. If you would like to discuss further, please feel free to open a question on meta. – rob May 02 '17 at 15:23
  • I use a diamond disc off of eBay for my router. It works pretty well but you need to know what your doing when sharpening. Otherwise it will not turn out. I like to work from the top of the tooth. – Ljk2000 May 04 '17 at 18:41

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.
