The hand-held cold cutting saw is a kind of hand-held electric tool specifically designed for cutting threaded steel. It adopts advanced cutting technology and precise mechanical structures. After cutting, the cut surface of the threaded steel is flat and smooth, with small deviations in perpendicularity and parallelism, which is beneficial to subsequent processing and use and can meet the cutting requirements of threaded steel of different lengths and specifications. It effectively prevents the splashes generated during the cutting process from hurting people and reduces the safety risks for operators.
