Breakproof Curved Cuts - The T 118 EOF Flexible for Metal Jigsaw Blade is breakproof for curved cuts in metal. Its milled, wavy-set teeth are designed for cutting sheet metal. Moreover, a narrow blade width enables quick turns while cutting. Made from BIM (bi-metal), the blade's fully hardened HSS (high-speed steel) tooth strip is bonded with its highly elastic HCS (high carbon steel) body, reducing the risk of breakage and providing both sufficient hardness and the required flexibility to cut perforated sheet metal made of standard-strength steel. It is equipped with a fine tooth pitch (1.5 mm) and cuts thin sheet metal with 1.5-4 mm thickness. For use with jigsaws with T-Shank clamping systems. Fits all T-shank jigsaws.
