1) Running linear velocity is 1/60 of the abrasive cutter, safe and no-park. Operation is suitable for near factory and flammable. Easy operation, natural cooling, automatic cutting, automatic stop, automatic switch off. 2)Smaller kerf, high cutting surface evenness (different from abrasive cutter, it doesn't need second cutting). Cutting surface is smooth, greatly improve the work efficiency. 3) The bi metal saw blade is cost-saving and has long life, one blade is equal to 5~8 abrasive discs. 4) Could adjust the angle of the blade directly, cutting angle: 45°~90°. 5)Deep cutting at fast speed, application:pipes, bolt, carbon steel, angle steel, structural steel, solid materials, hollow materials, stainless steel, chromium alloy, nickel base alloy, aluminum, copper, glass fiber, plastic, wood, etc.
