*Based on 9,500 SFPM (Surface Feet Per Minute) - the general optimum performance range for cutting concrete and masonry products, + or - 10%. For hard, dense materials such as stone and tile, the optimum performance speed is 10 - 25% less than the speeds shown above.
Blade shaft 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.
**This speed (RPM) represents the maximum safe speed (in revolutions per minute (RPM)) at which each blade can be used. Before using any blade, make sure the blade shaft (arbor) speed of the tool is within the "maximum safe" limit of that blade. | Core Drill Operating Speeds |

Note: Diamond blade cutting depths listed above are approximate. Actual cutting depth will vary with the exact blade diameter or saw type (or brand), or the exact diameter of the blade flanges. Cutting depth will also be reduced if saw components extend below the blade flanges.
