SFPM vs. RPM - Practical Machinist

Say the bore is roughly 6". All of my machines are manual, so there is no setting the rpm like I think you guys are talking cnc grinders. I just use the dial (which has labeled rpm) and go from there. I'm interested to see what rpm I should run, usually I run around 100-120 rpm on that example.

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.

33 Higher RPM leads to less torque, which means a higher risk of the tooling losing traction and spin out. Therefore, it's always safe to check what the optimal RPM is for the tool you are working with. Grinding Wheels and Blades: Below 7" in diameter, these tooling (and thus RPM) are designed for angle grinders.
