These quality Bosch metal jigsaw blades fit all jigsaws with a T-Shank clamping system The Bosch T123X (2608638473) Jigsaw Blades come in a pack of 5 and are designed for cutting thin to thick sheet metals between 1.5-10 mm, pipes + profiles, including aluminium. (BIM) blades contain a combination of high-carbon steel and high-speed steel. The T123X Progressor for Metal Jigsaw Blade is breakproof and delivers fast straight cuts in thick and thin metal. Featuring a tooth geometry with a progressively increasing tooth pitch, the blade enables work in materials with a wide range of densities. Additionally, the blade\'s milled, wavy-set teeth are designed for rapid cuts in sheet metal. Made from BIM (bi-metal), its fully hardened HSS (high-speed steel) tooth strip is bonded with its highly elastic HCS (high carbon steel) body, which reduces the risk of breakage and provides both sufficient hardness and the required flexibility to cut perforated sheet metal made of standard-strength steel. The jigsaw blade is equipped with a fine progressive tooth pitch (1.2-2.6 mm) and cuts a wide variety of thick and thin metal sheets with 1.5-10 mm thickness. For use with jigsaws with T-Shank clamping systems.
