MAKITA® BLUEMAK® Circular Saw Blades feature a blue coating which resists "pitch" build-up and reduces friction during cutting. It also has an added advantage of eliminating corrosion. BLUEMAK® blades are fully hardened and tensioned. They absorb impact and remain flat and true during the toughest applications. They feature teeth constructed from high-grade tungsten carbide with low wear rate which extends blade life. The teeth are precision honed for a sharper, longer lasting edge. Their thin-kerf design creates less waste while reducing the amount of feed pressure required.
