T 123 XF Progressor Jigsaw Blade for Metal. The T 123 XF Progressor jigsaw blade for metal is break-resistant and enables fast straight cuts in both thin and thick metal. The tooth geometry with progressively increasing tooth pitch allows for work with materials of varying densities. The milled, wavy teeth are designed for quick cuts in metal sheets. The tooth strip made of hardened HSS (High-Speed Steel) and BIM is reinforced with highly elastic HCS, reducing the risk of breakage while providing sufficient strength and flexibility to cut perforated steel sheets (standard thickness). The jigsaw blade features a fine progressive tooth pitch (1.2 to 2.6 mm) and cuts many strong and thin metal sheets with a thickness of 1.5 to 10 mm. It is suitable for use with jigsaws with a T-shank holder. Quickly cuts through thick and thin. Applications: For thin to thick sheets ranging from 1.5 to 10 mm in thickness. For pipes, closed profiles, and aluminum less than 30 mm thick. Package contents: 25 pieces.
