    If the disc is 0.25 inch thick, then a 0.5-in.-wide wear pattern should be showing on the wheel. If the wear pattern is, say, 0.75 in., your approach is too flat, which means too many of the grinding disc's grains are engaging at once. If the pattern is only 0.25 in. wide, your angle of approach is too high. 6. Keep consistent pressure ...
