According to OSHA grinding regulations, grinding machines must have safety guards. A guard must cover the machine's spindle end, flange projections and nut and have secure mounting that keeps it in line with the grinding wheel. Guards must also protect workers from the grinding wheel; workers should only be exposed to 90 degrees (75 percent) or ...

Power In Does Not Necessarily Equal Power Out. Input power, or the amount of power a tool needs to operate, can be misleading in judging the efficiency, power, and ultimate value of a grinder. A grinder may have an input power of 750 watts, but this number does not necessarily translate to actual grinding power.
