Diamond Blade Operation Speeds and Cutting Depths >

• Diamond Blade Operating Speeds Based on 9500 SFPM (surface feet per minute).

• Diamond Blade Cutting Depths listed below are approximate. Actual cutting depth will vary with the exact blade diameter, flange and saw type.

• The optimum blade RPM will depend on the machine and material and may vary from these values, The optimum RPM range for concrete and masonry products is +/- 10%    of the recommended RPM in the table.  The optimum RPM range for concrete and masonry products is +/- 10% of the recommended RPM in the table.                                The optimum range for hard, dense materials such as stone and tile is 10-25% less than the RPM in the table.
