AMMCO Brake Lathe Model 4000SP Combination Disc and Drum. The AMMCO® 4000-SP is designed for speed. It cuts rotors in one pass, with a high-quality finish. Positive rake tool bits allow for precision turning that produces superior machined surfaces every time. Set it and forget it. It's more efficient than ever because it integrates single speed spindle and feed rates for one pass precision finishes. Technicians can turn standard work quicker and easier. The 4000-SP uses positive rake tool bits for quality cuts you can see, time after time. The result of this simplification is one of the most accurate, durable, and easy-to-use machines you could ever put into your shop. Like every AMMCO® brake lathe, the 4000-SP is a precision tool that cuts to one-thousandths of an inch tolerances. With today’s more sensitive vehicles, this helps ensure customers get smooth braking and complete satisfaction. Key Features One-pass finishes – One-pass design provides exceptional rotor finish.
