The T 345 XF Progressor for Wood and Metal Jigsaw Blade delivers fast straight cuts in thin and thick wood with metal. Its tooth geometry with a progressively increasing tooth pitch allows for work in materials with a wide range of densities. Additionally, the bladeâ€™s milled, side-set teeth are designed for fast cuts. 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, making the blade appropriate for cutting metal-embedded wood with standard-strength steel components. Equipped with a large progressive tooth pitch (2.4-5 mm) and long length (132 mm), it cuts a wide variety of metal-embedded wood up to 65 mm thickness, e.g. soft nails, soft screws and soft fasteners. For use with jigsaws with T-Shank clamping systems.
