Lasts up to 50 times longer than a bi-metal blade. When hardened screws rust or get stuck in other ways, the only option is to cut them flush with the surface. The Expert Metal Max makes a perfect flush cut even in hardened metal. With its outstanding durability, it is the perfect accessory for craftsmen looking to cut hard materials with a multi-tool. The Expert Metal Max is the latest offering from Bosch Carbide Technology. The teeth are made not only from an extremely hard metal strip that can even cut stainless steel, but they also feature a high-tech additional coating for maximum longevity. The straight cutting edge is optimized for shortening, as it is less prone to slipping on screws and pipes. With the Bosch Expert Metal Max blade for multi-tools, metal can be sawed effortlessly. It even cuts through hardened window screws and rebar with ease. Starlock attachment for maximum power transfer and convenient blade changes in just 3 seconds.
