I ran into such a problem - the circular smokes, chokes, the material burns, but does not cut. I decided to make a small machine for sharpening the circular disk, with a diamond wheel using a grinder. Also, after a small transformation on the machine, it will be possible to sharpen the drills, and turn the machine into a grinding machine , but this is in other parts.
