    Jul 19 2019 · I have a 20" dia copper bonded diamond wheel (ballpark 200 grit if I recall) for grinding a spherical profile in tungsten carbide coating. Mostly got the metal bonded due to form stability over the grinding of several parts to reduce dressing time (not really for sharpening but for re-establishing wheel form).
