Evolution RAGEB 7-1/4-Inch Multipurpose Circular Saw is capable of cutting steel, aluminum, wood with nails in and plastics with just one blade. When cutting steel, the RAGEB cuts cold, no coolant is required. Because the material is cold it can be handled and worked on immediately. A combination of a hi-torque motor and gearbox, heavy duty construction and ultra high grade TCT blade enables the RAGEB to cut materials which simply weren’t possible before. A blade can cut up to 82 feet of 1/4″ mild steel before a replacement is required. Include’s Evolution’s 3 Year Warranty.
