Formula

n = (Vc × 1000) / (π × D) | Vc in m/min, D in mm → n in RPM

📖Formula Reference

RPM from Speedn = (Vc × 1000) / (π × D)
Vc in m/min, D in mm

Speed from RPMVc = (π × D × n) / 1000
Result in m/min

Typical Vc — Wood30–60 m/min (TCT blade, dry)

Typical Vc — Metal10–30 m/min HSS | 30–80 m/min TCT cold saw
