Diamond Saw Blade Recommended Operation Speed(RPM)
OPERATING SPEED
Recommended operating speeds for diamond blades are based on the blade size and the type of material to be cut. For optimum blade life and cutting speed, the actual operating speed will most like have to be adjusted for the type of aggregate and the amount of steel encountered.

When in doubt about the correct operating speed for a particular material, choose a lower speed rather than a higher speed. Then, if the blade cute well, try increasing the speed to improve blade life. To cut softer and more abrasive materials use a faster operating speed, faster forward speed, and more water. In general, higher operating speeds tend to lengthen blade life and slow cutting.
WARNING: NEVER OPERATE A BLADE ABOVE THE MAXIMUM OR “DO NOT EXCEED” RPM STAMPED ON THE BLADE, FAILURE TO COMPLY
WITH THIS SPEED WILL RESULT IN INJURY OR DEATH.
