(2) Rotate evenly and apply a little pressure to feed the taps. No additional pressure is required after the feed. (3) Each turning tap is inverted by about 45° at a time to cut the chips to avoid clogging. (4) If the tap is difficult to rotate, do not increase the rotational force, otherwise the tap will break.
