Drill stems are round, precision ground bar stock that is polished to tight tolerances. In its raw state, it is considered unhardened or soft for ease of processing.
Drill rods can be used to form various tools for woodworking, carving, machining, and the like. After the drill pipe is machined to the desired shape, it can be heat treated and then pulled back to the desired hardness.
