Combination Lathe for Brake Drums and Rotors, Less Adapters, 110V, 60Hz (Must be Purchased with a Bench Lathe Adapter Kit)

AMMCO™ Model 4000B Combination Disc and Drum Brake Lathe

The Ammco 4000B Combination Disc and Drum Brake Lathe has been professionals' first choice for more than 50 years. And for good reason. It's simple. It's fast. It's very precise. AMMCO combination brake lathes support rotors or drums using a standard one inch arbor. And like all AMMCO brake lathes, it almost never breaks down. It's no wonder that the 4000B has been a favorite of brake technicians everywhere since its introduction five decades ago.
