    General WARNING! A cutting blade may burst and cause injury to the operator. • Cutting blades are available in two basic designs; abrasive baldes and diamond blades. • High-quality blades are often most economical. Lower quality blades often have inferior cutting capacity and a shorter service life, which results in a higher cost in relation to the quantity of material that is cut.

    Government regulation requires a different type of guarding for carbide tipped blades not available on power cutters – a so called 360 degree guard.
