Bar threading machine

Product overview
The semi-automatic TMT Chaser rebar threading machine performs outside threading on forged TMT bars (EN8-D standard). Designed for high-production site use, the machine is available in three column models (A, B, C) covering 6 mm to 65 mm diameters. Constructed with high-density alloys and industrial components, it is intended to reduce operator time and maintenance needs during long operating periods.
