Calculate tapping feed rate from thread pitch and spindle RPM. Use it to check rigid tapping programs and avoid pitch mismatch between spindle speed and Z-axis feed.
Let our engineers find the right factory for your specs. 100% Quality Guaranteed.
Request a Proposal →Confirm whether the control expects feed per minute or feed per revolution. A unit mismatch can break taps quickly.
Multiply thread pitch by spindle RPM. For example, 1.25 mm pitch at 600 RPM needs 750 mm/min feed.
If feed and spindle rotation are not synchronized, the tap is forced to cut the wrong pitch and may break.
Yes. Rigid tapping depends on accurate synchronization between spindle speed and Z-axis movement.
Use this page to confirm the Z-axis feed required for rigid tapping from thread pitch and spindle RPM.

Use the calculator freely. If the result points to a tooling or process problem, we can source the exact carbide tooling you need from vetted factories in China. Compare factory-direct pricing.
Before you commit to a spec, it helps to know what the market pays for it. These are real, publicly listed factory prices — not a quotation, and not a guess.
We source the tool families below direct from vetted Chinese factories, matched to the material and tolerance you just worked out. Every batch ships with its material certificate and dimensional record.
SETTING UP A TAPPING OPERATION? If the taps come from a new supplier, set them up against that supplier's own recommendations — not the last brand's. See what to specify in a tap inquiry.
Feed equals pitch, so the tap has to be right before the program is. Send the thread, the material and whether the hole is through or blind.
