5-piece jigsaw blade set T 123 XF Progressor for Metal. Break-resistant, fast cuts in thick and thin perforated metal sheets. The bi-metal tooth strip made of hardened high-speed steel and a carbon steel body reduce the risk of breakage. Tooth geometry with progressively increasing tooth pitch for use with materials of varying densities. Fine progressive tooth pitch allows cutting of many strong and thin metal sheets from 1.5 mm to 10 mm. Compatible with all T-shank jigsaws. Overall length: 10 cm, tooth pitch: 1.2 mm to 2.6 mm, material: HSS. For use with jigsaws with T-shank fittings. The T 123 XF Progressor for Metal jigsaw blade is break-resistant and enables fast, straight cuts in thin and thick metal. The tooth geometry with progressively increasing tooth pitch allows for work with materials of different 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 metal sheets (standard thickness). The jigsaw blade features a fine progressive tooth pitch (1.2-2.6 mm) and cuts many strong and thin metal sheets with a thickness of 1.5 to 10 mm.
