Diamond Blades

(HS) Indicates high-speed diamond blades.

Recommended operating speed is based on 9,500 SFPM (Surface Feet Per Minute). The general optimum performance range for cutting concrete and masonry products is +/-10%. For hard, dense materials such as stone and tile, the optimum performance speed is 10-25% less than the speeds shown above.

Maximum safe speed shows the number of revolutions per minute (RPM) at which each blade can be used safely. Before using any blade makes sure the blade shaft (arbor) speed of the tool is within the �maximum safe� limit of that blade.

Blade safe speeds (RPM�s at no load) for most tools will be higher than the recommended operating speeds shown above. Under normal sawing conditions, the actual blade shaft speed of the tool will slow down under load, and should fall within the optimum speed range.
