SG 7100 Brake Rotor (grinds flywheels too!)

DCM Tech’s SG 7100 resurfaces heavy truck and auto rotors, both sides in one setup, to OEM or better finish and accuracy. Crosshatch ground finish provides a precision friction surface assuring optimum braking performance and brake pad life. Stock removal is minimum, keeping rotors in service longer, saving money and resources while providing a superior surface finish. Repair and Re-Use rather than replace, while increasing productivity! Rotors can be resurfaced in as little as 5 minutes with the easy to use bi-directional autofeed system. Wet grinding eliminates airborne dust and provides consistent results.
