Emuge’s line of NPT Taper Pipe Taps features a flute form with variable skip tooth geometry. According to the company, the flute design optimizes chip flow and clearance, improves thread finish and gaging, reduces machine downtime, and lowers tapping torque. According to the company, the taps are well-suited for materials that produce long, stringy chip formations and are prone to clogging flutes, such as aluminum, carbon steels, stainless steels and mold steels.
The taps are precision ground to produce internal NPT pipe threads to a close tolerance on thread dimensions and limits of size, and with high surface quality on the thread flanks to consistently achieve tight, leak-free joints at assembly. They are constructed of high speed steel and PVD-coated for longer tool life and improved thread finish.
The taps will be stocked in pipe sizes 1/16 through 1" NPT and in two lengths: the standard ANSI length and the longer DIN length, which enables additional reach, chip clearance and delivery of coolant. The DIN length is suitable for use on CNC machines with rigid (synchronous) tapping capabilities. The taps are offered in bright finish for wrought aluminum materials or TiN coating for steel materials. TiCN coating is also available upon request.
