Outstanding lifespan when cutting various materials! Progressive tooth pitch for separating material of any thickness. When cutting wood, a nail or screw can easily damage a standard jigsaw blade. This is not a problem for the versatile PRO Multi Material thick and thin T345XF. We designed it to make fast, straight cuts in workpieces of varying thickness with standard-strength steel fasteners. The PRO Multi Material thick and thin T345XF is made of bi-metal: it features a cutting edge made of high-speed steel (HSS) connected to a more flexible body made of carbon steel (HCS). This gives you the hardness and flexibility needed for processing wood with metal. The milled, offset teeth of the jigsaw blade ensure quick cuts, while the progressive tooth pitch allows for cutting different materials. The blade is 132 mm long, enabling you to cut workpieces with a thickness of up to 65 mm.
