Rex BSPT Threading Die Set, 1 – 2 Inch, Made in Japan - 16K030

Japanese BSPT Threading Die Set

The REX 16K030 Threading Die Set is a premium-grade, Japanese-made 4-piece industrial cutting tool engineered specifically for high-volume commercial plumbing, industrial piping, and precision gas fitting applications. Forged from heavy-duty alloy steel, this robust chaser set is expertly designed to cut clean, completely leak-proof British Standard Pipe Taper (BSPT) threads on medium-sized pipes ranging from 1-inch to 2-inches. By integrating an optimized 27 mm die width, these specialized alloy dies maximize cutting stability while significantly reducing the machine power consumption required for continuous, high-torque operations compared to standard full-width options.

Built to trace a perfect taper linearly across the pipe surface, this set minimizes mechanical stress and completely prevents pipe wall distortion. It is specifically calibrated to produce exactly 11 Threads Per Inch (TPI) at a strict 55-degree thread angle, delivering the exact surface contact needed for gas-tight, high-pressure seals. The inclusion of milled clearance channels and precision alignment notches guarantees smooth metal chip removal and effortless tool-free installation directly into REX profiling die heads, making it an indispensable, long-lasting asset for mechanical professionals.

Key Features & Benefits:

• BSPT Thread Standard Compatibility: Expertly cuts highly accurate British Standard Pipe Taper threads, ensuring completely tight, leak-free seals necessary for critical high-pressure fluid and gas delivery systems.

• Universal 1" to 2" Sizing Range: Offers a highly versatile operational range compatible with standard Rex pipe threading machines, allowing operators to seamlessly handle a wide variety of medium to large piping jobs.

• Easy Tool-Free Installation: Features distinct precision alignment notches that click directly and securely against the spring-loaded ball bearings inside the die head, enabling quick, effortless chaser swaps without the need to remove the head from the machine.

• Two-Step Blade Performance: The scientifically integrated bite profile allows the heavy-duty dies to cleanly strip away any external pipe coating while simultaneously slicing uniform, deep pipe threads in a single, efficient pass.

• Heavy-Duty Alloy Construction: Forged exclusively from high-grade alloy steel under strict quality control to endure punishing, continuous industrial use without chipping, cracking, or losing its sharp cutting edge.

• Efficient Chip Removal System: Specialized milled clearance channels allow harsh metal debris and shavings to flow out smoothly, actively preventing internal machine clogging, minimizing vibration, and leaving a polished, burr-free surface.

• Advanced Profiling System: Engineered exclusively to work with original REX profiling die heads, allowing the cutting tool to trace a mathematically perfect taper linearly, naturally lowering machine stress and extending operational lifespan.

• 11 TPI High-Load Contact: Precision-machined to consistently cut exactly 11 threads per inch, creating the absolute optimal surface area contact required to safely secure gas-tight, high-pressure industrial pipe joints.

• 55° Thread Profile Accuracy: Strict Japanese manufacturing tolerances guarantee a mathematically precise 55-degree thread angle, perfectly matching standard international BSPT specifications to completely prevent thread binding or leaking during assembly.

• Optimized 27mm Die Width: Intelligently built with a 27 mm cutting width to provide maximum mechanical stability and extremely smooth chip clearance during high-torque threading operations.

• Uniform Material Distribution: The robust alloy composition is perfectly and evenly balanced across all four die pieces to prevent uneven wear, ensuring that all cutting teeth dull at the exact same rate over years of use.

• Premium Japanese Craftsmanship: Engineered and manufactured entirely in Japan, delivering superior durability, exceptional wear resistance, and long-lasting sharpness that professional pipefitters rely on.
