Jul 26, 2001· Speed Is Nothing Without Torque. Tool speed and torque—the turning force of a grinder—reveal much about a grinder's power. The no-load tool speeds of most grinders likely are the same. However, the amount of stock removed per rotation of the grinding wheel is directly proportionate to the amount of force (torque) with which the wheel spins.
