A threading machine holds the pipe in a chuck, turns it against a die head and, on the better ones, cuts the pipe to length and reams the burr from the same stand, with oil pumped to the dies. They run from 100 to 400 lb, so they live in a shop or on a truck with a ramp. The RIDGID 300 sets the standard that the Steel Dragon and BlueRock machines copy: the dies and die heads are interchangeable, which is why spare dies are easy to find.
