T123 XF Progressor for Metal Jigsaw Blade is breakproof and delivers fast straight cuts for use in thick and thin metal. • Tooth geometry has progressively increasing tooth pitch, which enables work in materials with a wide range of densities. • Milled, wavy-set teeth are designed for rapid cuts in metal sheets. • Bi-metal, fully hardened high-speed steel tooth strip and highly elastic carbon steel body reduce risk of breakage. • For use with jigsaws with T-Shank clamping systems.
