Blades are available in combination steel, carbide tipped steel and masonry cutting types. Combination steel blades have more teeth for smooth cuts, while carbide tipped blades have longer life. Blades for the Nos. 800 and 810 Super Saws are not interchangeable with blades for the No. 550 Saw, and vice versa.
Caution: As these blades are subject to possible abuse, they are not guaranteed. Blades are not recommended for cutting metal as sparks can cause a fire hazard.
