The Fein 63502305000 Circular Saw Blade is a premium 150mm carbide blade designed for cold, fast and straight cutting in steel with the Fein F-IRON Cut 57 AS. Its wear-resistant carbide substrate provides a long service life, while the special tooth geometry helps minimise cutting forces and heat build-up for excellent dry-cutting results in construction steel. Vibration-dampening laser features support smooth running, and the large resharpening zone allows the blade to be resharpened multiple times.
