We took our basic combination Metal Lathe/Milling Machine and increased its capacity and usability. Start with a lathe spindle bore of 3/4 in. and a longer bed. Then added more change gears, inch-cut lead screws, a 4 in. 3-jaw chuck, reversing switch and so much more. This is an excellent machine for anyone, from the home hobbyist to the seasoned machinist. You get a lot of machine in a very small package with all the features you need for just about any job.
