The 28 blade ensures precise flush and deep cuts of wood, metal and plastic. It cuts precisely from the beginning. The blade's closed interface installation system is sturdy and durable. It can perform highly accurate cutting, can directly transmit power and reduce shaking. This versatile blade can also cut through very hard wood and metal materials, including unhardened nails and screws, non-ferrous metal pipes and smaller-sized profiles. When cutting non-hard metals and abrasives, the BIM (bimetal) combination of HCS (high carbon steel) blades and HSS (high speed steel) teeth has wear resistance and heat resistance, thus ensuring the long life of the blades. The tight 3D connection between the machine and the accessories enables the installation system to produce maximum power transmission. It is suitable for all power tools and common multi-function tools.
