The Fein 63502306000 Circular Saw Blade is a premium 150mm carbide blade designed for straight cuts in non-ferrous metals such as aluminium, copper and brass with the Fein F-IRON Cut 57 AS. Its special tooth geometry helps reduce cutting forces and heat build-up for clean dry cutting, while the carbide grade is selected specifically for machining aluminium to maintain excellent cutting quality over a long service life. The narrow cutting width also reduces power demand, helping support longer battery runtime, and the large resharpening zone allows the blade to be resharpened multiple times.
