  • Differences Between Drill Rod, Round Bar and Steel ...

    2016-5-27 · Drill Rod. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter. While typically round, drill rods may also be fabricated in square shapes. They are also often tempered prior to machining. This process involves heating the steel to relieve the hardness and to make the steel more workable.
