The axial coolant duct design helps flush chips away from the cutting edge, which reduces the frequency of chip binding and extends tool life. Thread quality is also enhanced as chips are cleanly ejected from the cutting area and cannot score existing threads. Minimal coolant pressure is required, with higher coolant pressures delivering optimum performance.

Form tapping has many advantages over traditional cut tapping, and is well-suited for steel applications. A formed thread (sometimes referred to as a rolled form ) is a stronger thread than a cut thread. The flanks of the thread have an excellent surface finish and the form tapping operation is actually faster than a cut thread. Additionally, Guhring form taps incorporate premium base material with a superior post polished surface finish for added tool life and superior thread quality.
