Any pointers on sharpening circular saw blades, can a 3 cornered file be used, what about setting the teeth. Also how about simple tools for sharpening carbide teeth

I think you will find poor results if you try to hand sharpen a circular saw, especially carbide. Files are softer than carbide and will not cut. I have given up since I now can buy a new carbide for $12 at the big box stores. I save my old ones for cutting stuff like Duroc and Hardiboard.

Thank you so much.

I pulled the blade out and viced it into a worktable. Used an old rusty fine file on it. Worked quite well.

Here's a good quicky tutorial on how to sharpen your circular saw blades.

Takes about 15 - 20 minutes. Not rocket science but if you don't see decent results, you simply aren't doing it right.

Any suggestions & comments are welcome.

For a carbide tipped blade, I use a grinding wheel on my dremel tool. Work slowly making sure it stays cool, and it works really well. If you don't have a dremel, you can get a cheap copy at the local Harbor Freight store that is cheap but works surprisingly well for this kind of work. Good luck

Just remember, the bevel on the teeth alternate every other tooth. You can use a grinder, set the angle, and be quick careful not to overheat the metal as it will weaken it.
