Thread axially miscut

Thread axially miscut
Possible causes Solution
spiral-fluted taps, corresponding to our design, are applied with too much pressure for initial tapping with spiral-fluted taps only light pressure required for initial tapping. The tap should immediately be applied within the tension/compression range
initial tapping pressure too low for taps with spiral point corresponding to our form “B” taps with spiral point or left hand spiral require higher axial pressure.
Ensure tap operates within the tension/ compression range
