Premium HSS Durability: High-Speed Steel body, hardened and tempered so the cutting edges survive repeated threading on site rather than dulling after a handful of pipes.
Short-Chipping Material Master: Cuts clean threads in steel, stainless, brass and copper pipe — the materials plumbers and fitters actually work with every day.
Precision Thread Profiles: Ground to the NPT taper so the joint seals under pressure without excessive PTFE tape or compound.
End-to-End Wholesale Customization: Full NPT and BSP size range, supplied loose, in sets or in retail packs with your own brand marking.
Adjustable Split Design: The adjusting screw opens or closes the die a fraction, letting the fitter recut a damaged thread or ease a fitting that runs too tight — no scrapped pipe.
