Drill Extension Rod Details
Drill Rod (DR) is tool steel manufactured into round bars and precision ground to insure that the diameter is bright, clean, and free of surface defects and carburization. It may also be referred to as precision drill rod, bar stock, round stock, or drill stock. After the grinding process, a polishing process is normally done to insure a smooth surface finish and tightly controlled dimensional tolerances. Drill Rod can be the raw material used to manufacture drill bits, dowel pins, taps, punches, reamers, and shafts.
Drill rod is generally purchased in an annealed condition so that the tool steel can be readily machined. After machining the pieces can be heated for greater hardness and better durability.
When tool steel rods are purchased in a hardened, heat-treated condition, they may be referred to as drill blanks. Drill blanks and drill rods used for mining or for oil and gas pipelines are a different class of products which are not included in these pages.
