Rex BSPT Threading Die Set, 1/2–3/4 Inch, HSS, Made in Japan - 166007

Premium Japanese HSS Threading Die Set

The REX RX166007 Threading Die Set is a premium industrial tool engineered to deliver flawless, leak-proof pipe connections in the most demanding environments. Crafted in Japan from superior High-Speed Steel (HSS), this set of four high-performance die chasers is purpose-built to outperform standard alloy dies in both heat resistance and longevity. It is specifically formulated to effortlessly cut precision tapered threads into extremely tough materials, including heavy-walled carbon steel and industrial stainless steel pipes. Designed for seamless, plug-and-play compatibility with REX N150A threading machines (using die heads 295649 or 292810), these dies ensure consistent, professional-grade results for mechanical contractors who refuse to compromise on quality.

Adhering strictly to the British Standard Pipe Taper (BSPT) specification, the RX166007 accommodates both 1/2-inch and 3/4-inch pipe diameters, producing a precise 55° thread angle with a 14 TPI pitch. The optimized cutting geometry ensures an immediate, clean "bite" into the pipe, promoting smooth chip removal while drastically reducing harmful vibrations and physical strain on the machine. Featuring a wear-resistant surface treatment and a heavy-duty physical build—weighing approximately 500g with a 27mm width—this tool provides the ultimate structural stability required for high-torque threading. It is the definitive standard choice for critical applications in plumbing, oil and gas, and heavy pipeline installations.
