For use with jigsaws with T-Shank clamping systems. The T 321 AF Speed for Metal Jigsaw Blade delivers fast straight cuts in metal. Featuring a patented back-taper body and thin kerf design, the blade provides unrivalled cutting speed, while its patented tooth geometry of aggressive and robust teeth further increases cutting speeds. The blade's milled, wavy-set teeth are designed for cutting metal sheet. Made from BIM (bi-metal), its fully hardened HSS (high-speed steel) tooth strip and a highly elastic carbon steel body reduce the risk of breakage and make the blade breakproof. Furthermore, it provides both hardness and flexibility to cut pipes and open metal profiles made of standard-strength steel. The jigsaw blade is equipped with a very fine tooth pitch (1.2 mm) that cuts thin-wall metal pipes and profiles with 1-3 mm wall thickness, while the long-length blade (132 mm) cuts pipes and profiles up to 65 mm diameter.
