Uniform rotation (2) hands and slightly pressure to tap into the knife, no need for the feed pressure. (3) Turn the tap every time reversal of about 45 ° to cut the chip, in order to avoid congestion.
(4) If the tap is not difficult to increase the rotational force of the rotation, otherwise tap will break.
