1800 or 3600 rpm for a 7" bench grinder
You say you're going to use the grinder for HSS tools. I strongly recommend a 3600 RPM grinder at least 3/4 HP. 7" is a good size. As the wheel wears you go through the 5.8" dia optimum. When the diameter reaches 5: or so, it still has sufficient FPM to cut almost efficiently. An 1800 RPM grinder OTH is slow to start with.
