A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter. Oftentimes they are tempered prior to machining to make the steel more workable. There three types of drill rods: air hard, water hard and oil hard.Close
