The T 121 GF Speed metal jigsaw blade makes fast, straight cuts in metal. The blade's bevel and thin cutting design allow for maximum cutting speeds. The patented tooth geometry and the combination of aggressive, robust teeth further increase the cutting speed. The milled, wavy teeth are designed for cutting metal sheets. The tooth strip made of hardened HSS (high-speed steel) and BIM (bimetal) is reinforced with highly elastic HCS (carbon steel), reducing the risk of breakage and making the blade break-resistant. This ensures sufficient strength and flexibility to cut perforated steel metal sheets (standard thickness). It is equipped with a very fine tooth pitch (0.8 mm) to cut very thin metal sheets with a thickness of 0.5-1.5 mm.
