T 321 AF Speed for Metal Jigsaw Blade. The T 321 AF Speed for Metal jigsaw blade enables fast straight cuts in metal. The blade's bevel and thin cutting design ensure the highest cutting speeds, while the patented tooth geometry and the combination of aggressive, robust teeth increase cutting efficiency. The milled, wavy teeth are designed for cutting metal sheets. The tooth strip made of hardened HSS and BIM is reinforced with highly elastic carbon steel, reducing the risk of breakage and making the blade break-resistant. It provides sufficient strength and flexibility to cut pipes and open metal profiles made of steel (standard thickness). The very fine tooth pitch (1.2 mm) cuts thin-walled metal pipes and profiles with wall thicknesses of 1 to 3 mm, while the long length (132 mm) allows for cutting pipes and profiles with a diameter of up to 65 mm. Designed for use with jigsaws with T-shank fittings. Fast, break-resistant, and durable. Applications: For thin sheets, perforated sheets from 1 to 3 mm thickness, for sandwich materials less than 65 mm thick, for thin-walled pipes, closed and open profiles, as well as aluminum less than 65 mm thick, for fiberglass/epoxy less than 65 mm thick. Package contents: 5 pieces.
