Ammco brake lathe accessory Boring Bar Heavy Duty Truck Tractor Drum

This 1-1/2 Hex Boring Bar adapter is 11 long and entire unit is 17 in Length. This can fit Ammco or be adapted to fit other brands of Brake Drum Turning Lathes. We think this is mainly for very Large size Brake Drums from a Semi-Truck Tractor Trailer when machining them on your Brake Lathe or regular Machine Shop Metal Engine lathe. The Lower part of the Head is casting number C 7693 and the upper is B 7694 and looks to hold another 1.5 hex boring bar or possibly a large round unit. This is a very hard to find unit and this is the only 1 we see out there for sale. Call
