Diablo 9-In. Bi-Metal Medium Metal Saw Blade, 5-Pack are specially designed to make metal cutting applications faster and easier. The full contact arched design features more working teeth to cut through the material in fewer passes, reducing heat build-up and providing five times longer cutting life. These blades feature a double tooth configuration with small gullets that enable fast material removal and enhanced durability. The Perma-shield non-stick coating helps prevent heat build-up, gumming, and corrosion, while the 1-inch demolition body reduces vibrations for straight, precise cuts. Model Number: DS0914BF5
