I am looking for recommendations for a wheel for my surface grinder that I will be using for cutter grinding. 7" diameter with a 1 1/4 hub. It is for drill sharpening device where the radius on the edge of the wheel is an important part of the relief of the web.
What are your recommendations for the best compromise between hardness and grit to hold a good radius without burning the drills? An undersize 54I popcorn would lose the radius every couple of drills. A 80H holds the radius well but burns.
