forming tap is a tap that processes threads by plastically deforming the minor diameter of the pilot holes. Since the threads are machined without cutting, there are no chips.
forming tap , New Roll Tap, Fluteless Tap, Raised Tap, and Forming Tap also refer to forming tap .
On the other hand, straight fluted tap spiral pointed tap spiral fluted tap is called a cutting tap because it takes out chips and processes them into the shape of a thread.
Difference Between Grooveless Tap and Cutting Tap
・ Grooveless taps do not produce chips.
・ Compared to cutting taps, it is more durable.
・ Compared to cutting taps, torque is applied.
・ The pilot hole diameter is different.* Compared to cutting taps, the range of pilot hole diameters to be aimed at is also narrower.
It is necessary to select a drill diameter that takes into account characteristics such as the finished diameter of the pilot hole being easily enlarged or reduced.
Machining with a grooveless tap is greatly affected by the pilot hole diameter.
While there are advantages such as no chips and a long tool life , it is necessary to pay attention to the selection of pilot hole diameter at the beginning.
