Genuine RIDGID 161 Geared Threading Dies - Lot of Complete Dies & Parts Threading Capacity of 4 to 6 Inches This lot features a complete set of four authentic RIDGID 161 Geared Threading Dies, specifically engineered for the high-torque demands of large-diameter pipe fabrication. Designed exclusively for the RIDGID 161 Geared Threader, these dies are essential for professionals threading 4" to 6" pipe.Manufactured from High-Speed Steel (HSS), these dies offer the superior hardness and heat resistance necessary to produce clean, industrial-grade NPT threads on black iron, galvanized, and stainless steel. Because the 161 system relies on precision gearing, these dies are matched to ensure perfectly balanced cutting pressure and consistent thread taper across every pass.Technical SpecificationsPipe Capacity: 4", 4 1/2", 5", and 6" (100mm - 150mm)Thread Type: NPT (National Pipe Thread)Material: Premium High-Speed Steel (HSS)Compatibility: Exclusively for RIDGID 161 Geared ThreadersSet Count: 4 Matched Dies (Must be used as a complete set)Direction: Right-Hand (RH)Key FeaturesIndustrial Precision: Specifically ground to create leak-proof, high-pressure seals on large-bore piping.Enhanced Tool Life: The HSS construction maintains sharp cutting edges significantly longer than standard alloy alternatives, even in high-production environments.Optimized Geometry: Engineered to work seamlessly with the RIDGID 161 gear-reduction system, minimizing the physical force required for manual or powered threading.Matched Set Performance: Each die is labeled and calibrated to work in unison, preventing uneven thread depth or "chatter" during the threading process.
