WHAT IS DRILL ROD?

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.

NOMINAL SIZES

Drill Rod is manufactured in various sizes of diameters and lengths. In ROSCHEN the greatest variety of sizes are in fractional inches. Diameters range from 1/16" to 3" with many fractional-inch sizes in between. Many letter-size and number-size diameters are also available. The lengths are 3 feet or 12 feet (36" or 144"). Some manufacturers will cut 12 foot rods in half before shipment for an extra charge. This produces two 6 foot rods that may be less expensive to ship. In metric DR, the diameters range from 2mm to 30mm and the length is about one meter.
