The T 718 BF Flexible for Metal-Sandwich Jigsaw Blade is breakproof when making straight cuts in metal. Its milled, wavy-set teeth are designed for cutting metal-sandwich panels. 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 metal-sandwich panels. It is equipped with a fine tooth pitch (2.0 mm) and long length (180 mm) for cutting metal-sandwich panels up to 120 mm thickness. For use with jigsaws with T-Shank clamping systems.
