4 x Universal Blade (BIM, 5/11 TPI) These black 150 mm blades are made from flexible bi-metal (BIM) and feature a variable tooth count of 5 to 11 teeth per inch. This geometry allows them to be used as all-rounders ("Metal & Speed Wood"). They are suitable for nail-embedded wood as well as metal profiles and are characterized by high break resistance. 4 x Softwood Blade (CRV, 6 TPI) The blue 152 mm blades are made from chrome-vanadium steel (CRV) and have a coarse tooth count of 6 teeth per inch. They are optimized for "Speed Softwood." With their large chip spaces, they enable very fast cuts in pure softwood and green wood, but are not suitable for metal. 4 x Coarse Demolition Blade (BIM, 6 TPI) These black 150 mm blades are also made from durable bi-metal (BIM) and feature a constant, coarse tooth count (6 TPI). They combine hardness with aggressiveness for the "Metal & Speed Wood" application. The blade is ideal for fast cutting in thick materials, such as wooden beams with nails or thicker metal.
