The EXOPRO® XPF and S-XPF represent a new evolution in forming tap technology. These form taps generate up to 50% less torque versus other forming taps, making it feasible to tap materials up to 40 HRC and sizes up to or exceeding 1 in Dia.

EXOPRO® Thread Forming Tap, Extreme Premium Fluteless High Performance, Series: 16250, Measurement System: Imperial, #2-56, UNC, 2.5P Modified Bottoming Chamfer, 0.385 in Thread Length, 1.77 in Overall Length, Class of Fit: 3B, 0.14 in Shank Dia, 0.0769 to 0.0787 in Tap Drill, 0.188 in L x 0.109 in W Square Size, HSS-CO, V-Coated, H2 Thread Limit

For automobile engines, higher performance with XPF is achieved when running at higher SFM, nickel alloys such as inconel 718 for thread sizes under 1/4 in applications
