The S 123 XF Progressor for metal reciprocating saw blades makes fast, straight cuts in thick and thin metal. Its progressively increasing tooth pitch (1.8–3.2 mm) allows for quick cuts in materials with varying densities. Additionally, the bi-metal blade is designed for cutting steel pipes and profiles of normal thickness. It features a special tooth shape for cutting steel with wall thicknesses ranging from 1 to 8 mm. The blade has a standard length of 150 mm and a cutting capacity of up to 100 mm. It is suitable for reciprocating saws with 0.5-inch universal shank systems.
