diamond cutting steel.... Friction cutting? Answered
recently got a diamond wheel for angle grinder. tho it is marketed to cut tile, marble, etc, i tried it on steel. cuts quick enough, but leaves huge burrs. burrs 4x thicker than the workpiece. seems the blade just melts and squishes the steel out of the way. it works, kinda, leaving a hazardous ragged edge on the work... i see why they dont market those blades for steel.
im reminded of friction cutting blades.
