Recommended Operating Speeds for Circular Saw Blades
For extended blade life and quality of cut, saw blades should run between 10,000 and 18,000 SFPM (surface feet per minute). Never exceed 18,000 SFPM! To calculate SFPM: (1) Multiply the diameter of the blade times Pi (3.1416) to get the circumference, then multiply circumference by RPM to get inches per minute and (2) divide the inches per minute calculation (from step 1) by 12 to get the feet per minute. Best results on most materials would be about 15,000 SFPM.
