A cold saw blade is a circular metal cutting tool, typically made of high-speed steel (HSS) or HSS with cobalt (HSS-Co). It has a high tooth count (usually 160 to 300+), operates at speeds between 1,200 to 3,500 RPM, and is primarily used for precision cutting of metal materials like steel, aluminum, and stainless steel. Coolant is often used for heat dissipation, and proper safety precautions are essential when using cold saws.
