Brake Lathe Drum and Rotor - Coats fmr. Ammco-Coats / Hennesy

Part #: 3860B

The Combination Lathe with the Right Combination of Speed and Value

AMMCO`s new Model 3860 brake lathe is for shops that need speed, disc/drum versatility, and low maintenance operation.This is a new design that incorporates many "Voice of the Customer" features that shops have told Ammco they wanted to see in a lathe. Ammco listened, and they built a brake lathe that works for a broad range of businesses.

The Model 3860 lathe features negative rake tools that greatly increases the life of cutting bits. A new chip diversion guard system keeps metal shavings out of the operating mechanisms of the unit, stopping hang-ups and cutting maintenance. The 3860 has been designed for faster setup between drum and rotor operation, and easier drum machining.
