The high speed RED ROOSTER RRI-34100 die grinder is specifically destined for grinding and de-burring with hardmetal burrs on a 3mm shaft. The good torque and power ratio of the gear motor transmit a stable speed of the shaft, even under loads. Use for moulds and dies but also for non-metallic materials. Characteristics: • Low noise-level by means of integrated exhaust-air hose with muffler. • Turn-switch for flexibility in handling of the tool. • Highly accurate roundness of the running shaft ensures long lifetime and low vibration levels. • This grinder can be used with oil-free air.
