Metric Tapping Speeds and Feeds Calculator

Metric Tap Feed Calculator

Calculate optimal spindle speed and feed rate for metric tapping.

How to Use Metric Tap Feed Calculator

Easily calculate the optimal feed rate for metric tapping operations.
Simply enter the thread pitch (in millimeters) and spindle speed (in RPM) to find the correct feed rate in millimeters per minute (mm/min).

  • Thread Pitch: The distance between each thread (in millimeters).

  • Spindle Speed (RPM): The number of revolutions per minute.

Formula used:
Feed Rate (mm/min) = Thread Pitch (mm) × Spindle Speed (RPM)

This calculator helps you set accurate feed rates for tapping metric threads on CNC or manual machines, ensuring proper thread quality and reducing the risk of tap breakage.
Perfect for machinists, CNC programmers, and anyone working with metric fasteners.
