Product Description

Drill Rod is a round metal bar stock made from tool steel that has been ground and polished to tight tolerances. It is generally supplied unhardened and is therefore readily machine workable making it an ideal product to use to manufacture tools.
Drill Rod is finished within very tight tolerances to ensure there are no defects, allowing for a final product that can withstand shock, is hard wearing, resists deformation, and can keep an edge while at elevated temperatures. Tools made from Drill Rod are particularly well suited for working other materials.

Drill Rod is made by machining tool grade steel into rods. The rod is precision ground to a specific tolerance and then polished to have a clean and smooth surface. The polishing process helps ensure the specific tolerance is maintained.
Drill Rod is often tempered prior to machining to relieve the hardness and increase the machinability of the steel. The tempering process involves heating the rod up until it glows red, and then cooled, or quenched in water, oil, or air depending on the Drill Rod grade. The rods are then coated with a rust preventing oil for storage to ensure the polished finish remains untarnished.
