Internal and External Jaws: The 3-jaw lathe chuck comes with two sets of jaws—inside and outside ones—to extend its holding range, and therefore allows you to handle a wide variety of stock sizes.

Wide Application: The metal lathe chuck is widely applied to metal lathes for the general turning of shafts and some more delicate materials. It would be the perfect choice for your lathe machine.
