Alloy steel jaw, interface carburization treatment of 0.8-1.1mm deepness, whole quenching process, making the jaw inside more tenacity and outside more hard, and take the jaw cover for protect rim
For North America region used 120V/1ph/2.0HP motor,more strong power and high efficiency working.
The body use 3mm thickness steel, high strength, solid welding, few vibration.
The computer board adopt advanced welding technology, moistureproof,dustproof and anti-static electricity, more longer life.
