Rex BSPT Threading Die Set, 1/2 - 3/4 Inch, Made in Japan - 161907

BSPT Threading Die Set

The REX 161907 threading die set is a highly specialized, 4-piece cutting tool manufactured in Japan to deliver mechanical sealing reliability. Forged from high-grade alloy steel, this set is designed specifically to cut British Standard Pipe Taper (BSPT) threads on medium-sized pipes ranging from 1/2" to 3/4". By maintaining a strict 55-degree thread angle and consistently producing exactly 14 Threads Per Inch (TPI), these dies ensure the exact surface-to-surface contact required for completely gas-tight, leak-proof joints. The integration of an optimized 27 mm die width maximizes cutting stability, lowering the required machine power consumption during high-torque threading operations.

Mechanically, the 161907 set is built to work seamlessly with REX profiling die heads, actively minimizing mechanical stress and preventing pipe wall distortion by tracing a mathematically perfect taper linearly across the material. The tool-free installation mechanism relies on precision alignment notches that click securely into the spring-loaded ball bearings of compatible machines, including the REX N50A, N80A, N100A, and N150A series. Furthermore, the dies incorporate specialized milled clearance channels that direct harsh metal debris and shavings away from the cutting zone. This continuous chip removal process prevents internal clogging, reduces operational vibration, and guarantees a polished, burr-free thread profile over years of continuous commercial use.

Key Features & Benefits:

• Machine Compatibility: Fully engineered to integrate seamlessly with REX threading machine models including the N50A, NP50A, N80A, NP80A, N100A, and N150A series.

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

• Universal 1/2" to 3/4" Range: Offers a versatile operational range, allowing operators to handle medium-sized piping jobs continuously without changing the die head configuration.

• Tool-Free Installation: Features distinct precision alignment notches that click securely against the spring-loaded ball bearings inside the die head, enabling quick, effortless swaps without head removal.

• Two-Step Blade Performance: The strategically integrated bite profile allows the dies to cleanly strip away external pipe coatings while slicing uniform, deep threads in a single pass.

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

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

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

• 14 TPI High-Load Contact: Precision-machined to consistently cut exactly 14 threads per inch (TPI), creating the optimal surface area contact required to secure high-pressure industrial joints.

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

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

• Uniform Material Distribution: The robust alloy composition is evenly balanced across all 4 die pieces to prevent uneven wear, ensuring the cutting teeth dull at the exact same rate.

• Premium Japanese Craftsmanship: Engineered and manufactured entirely in Japan, delivering superior durability and long-lasting sharpness that professional pipefitters demand.
