Left-Hand Metric Threading Die M18 HSS, TF

This professional solid circular threading die by TF is a high-precision industrial tool engineered specifically for cutting and repairing left-hand external metric threads (LH). Crafted from high-performance High-Speed Steel (HSS), it delivers outstanding structural hardness, superb torsional resistance, and exceptional edge retention, preventing thread tearing and guaranteeing flawless surface calibration even under demanding workshop conditions.

Featuring a nominal thread size of M18 paired with a standard pitch of 2.5 mm (Left-Hand), this precision die is highly optimized for mechanical setups where constant rotational forces or heavy vibrations would cause conventional right-handed fasteners to loosen. It is widely utilized in drive shafts, industrial turnbuckles, heavy machinery components, agricultural equipment, and specialized maintenance operations. It is perfectly suited for cutting clean threads on standard carbon steels, ferrous materials, and non-ferrous metals, ensuring absolute geometric accuracy conforming to international ISO metric thread standards.
