- 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
