Dave, I try to avoid doing any finish grinding with a solid metal wheel. I put 1/8 cork on my 1x42 top wheel so it wouldn't ripple when trying to do a clean dip grind. The rubber helps to do a smooth grind. If you're just grinding a small recess the solid is fine, but when you want to finish it rubberized wheels are the best and use lighter pressure even with the rubber. Contact wheels are covered with rubber for a reason. To reduce rippled grinds. I would rather use a sanding drum on a drill press for some applications than a hard metal wheel.
