- The speed given are guide values acc. to general information and can vary depending on tap manufacturer.- For optimal production and correct speed, we suggest following the specifications of the tap
manufacturer.- Furthermore, the maximum speed of the tapping attachment must not be exceeded.
Calculation:
vc × 1000n = d × π
Example: M8 with 40 m/min
40 × 1000n = = 1592 U/min (RPM) 8 × 3.14
Tapping speed vc = m/minRPM n = U/minDiameter d = mm

- The speed given are guide values acc. to general information and can vary depending on tap manufacturer.- For optimal production and correct speed, we suggest following the specifications of the tap
manufacturer.- Furthermore, the maximum speed of the tapping attachment must not be exceeded.
Calculation:
vc × 1000n = d × π
Example: M8 with 30 m/min
30 × 1000n = = 1194 U/min (RPM) 8 × 3.14
Tapping speed vc = m/minRPM n = U/minDiameter d = mm
