Note: CRITICAL: Never exceed wheel rated RPM. Use guard at all times. Stainless steel requires iron-free wheels to prevent contamination.
Reference
RPM = SFPM x 12 / (pi x wheel diameter)
Max RPM must not exceed rated speed on wheel
Typical SFPM: bonded wheels 5500-9500, coated 4500-7500
Never exceed rated RPM - wheel can burst!
