Meters per minute to spindle speed
Type a value in m/min to get it in rpm instantly.
15,915.49rpm
That's 1.67× as fast as carbide in brass, while carbide in aluminium is 1.2× faster.
Convert the other way: rpm to m/min
What it means
How fast is that cut?
Pick the diameter of the rotating part: the tool on a mill or drill, the workpiece on a lathe. Speeds for materials are starting points; follow the tool maker’s data.
The math
How to convert m/min to rpm
rpm = 1000 × v ÷ (π × D) with v in m/min and D in mm; rpm = 12 × SFM ÷ (π × D) with D in inches.
Example: 500 m/min = 15,915.5 rpm.
RPM figures on this page are for 10 mm. Pick another diameter above and they change.
