Brand new About this product
The Thread Cutting Machine by National Cutting Tools is an industrial workhorse designed for accurate external thread cutting on steel pipes, bolts, threaded rods, and construction bars. In fabrication shops and fastener manufacturing units, producing uniform threads by lathe single-pointing is slow and labor-intensive; this dedicated threading machine cuts completed threads in a single fast pass using multi-tooth tangential chasers. Built on a rigid cast bed, the machine features an all-geared headstock providing multiple spindle speeds (40 to 80 RPM) to match the machinability of mild steel, high-tensile EN-8/EN-9, stainless steel, and TMT rebar. The adjustable self-opening die head accommodates metric, BSW, UNC, BSP, and NPT pitch sets, delivering clean, burr-free threads conforming to international gauging tolerances. Key Features Tangential Chaser Die Head: Four-chaser tangential arrangement provides balanced cutting forces and allows chasers to be reground multiple times for low running cost. Adjustable Multi-Speed Headstock: Geared transmission enables quick speed changes to optimize cutting feet-per-minute for small bolts or large-diameter tubes. Self-Centering Heavy Vise: Dual-screw mechanical or pneumatic vise holds round, square, or hexagonal bar stock on exact spindle center. Micro-Adjustable Length Stop: Positive mechanical trip bar triggers the automatic die-opening mechanism at the exact required thread length. Continuous Coolant Lubrication: Electric pump and chip separator tray supply filtered cutting oil directly to the cutting edges. Applications Manufacturing structural foundation bolts and U-bolts Threading scaffolding tie rods and couplers Plumbing, fire-fighting, and conduit pipe end threading General job-shop fastener threading across manufacturing belts Manufactured and tested at our Ludhiana facility. Each unit undergoes trial threading on client steel grades to verify pitch diameter, flank angle, and thread lead before packing and dispatch.
