A Tap , Use in drilling machine

The A Tap is self-guiding, so it can also be used on drilling machines. However, not only A Tap , but also Tap It is necessary to advance one pitch in one rotation during machining (in the case of a single thread). In the case of drilling machines, the feed rate (mm/min) is manual, so when high efficiency and high load conditions are expected, spiral Tap and point Tap may deviate from one pitch in one revolution due to the machining load. In order to extract the performance of A Tap that enables high-efficiency machining, feed stabilization is required.
