Since its introduction nearly 40 years ago, the AMMCO Model 4000 brake lathe has been a favorite of brake technicians everywhere.
And for good reason. It’s simple. It’s fast. And it almost never breaks down.
The Ammco Model 4000 brake lathe features twin cutter tools and quick drum-to-rotor changeover. Adjustable spindle speeds allow for easy rough cut/finish cut settings, and there’s an infinitely adjustable spindle-feed gear box.
The Ammco Model 4000 supports drums or rotors up to 100 lbs. using the standard one inch (25.4mm) arbor, or up to 200 lbs. using the optional 1.875 inch (47.63mm) arbor (Part #3481).
It’s the best seller because year after year it performs the best.

Model 4000B-SP Single Pass Disc/Drum
Proven Performance, Legendary Reliability with One Pass Machining
AMMCO 4000B-SP Single Pass Disc/Drum Brake Lathe
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 4000B-SP uses positive rake toolbits 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.
One-Pass Finishing Means You Complete The Job Faster
The Ammco 4000B-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.
Easy, Efficient Operation
Work quickly and efficiently. Ergonomics are designed for minimal operator movement. Twin cutter dials and depth of cut are clearly marked, and even new operators can quickly turn rotors like seasoned professionals.
Superb Accuracy For Your Customer Satisfaction
Like every Ammco brake lathe, the 4000B-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.
Industry Leader In Durability
Many Ammco 4000s are still in service after 40 years of continuous use. Massive “floating spindles” offer superior weight support, and a unique patented system provides a constant oil feed to bearings. It’s
designed to work like brand new—for a long, long time.
