Click the link for more information.&lt;br /&gt;&lt;br /&gt;This Oilcrat Ground and Polished Drill Rod is made by Precision Marshall Steel Company. The steel type is AISI O-1 oil-hardening tool steel, annealed for easier machining. It is an electric furnace-melted oil-hardening tool steel with a full-spheroidized structure. A non-shrinking general purpose tool steel, it has excellent abrasion resistance, toughness and machinability characteristics.&lt;br /&gt;&lt;br /&gt;It has uniform machining properties and consistent response to heat treatment through carefully controlled chemical analysis. Identification of each production lot is maintained, and a certified chemical analysis can be provided upon your request.&lt;br /&gt;&lt;br /&gt;The drill rod ends are saw-cut and chamfered or deburred when the diameter is 10mm or greater. This processing protects other rods from scratching, helps your set-ups and improves safety in handling. Smaller diameters are accurately cut with automatic die-cutters. At least one end is painted green for easier identification of the steel type.&lt;br /&gt;&lt;br /&gt;The Diameter |D| tolerance is ±.008mm for rod diameters less than 3mm, ±.013" for diameters 4mm-12mm, and ±.025mm for diameters of 13mm greater. The Length |L| tolerance is +2.60/-.60mm.&lt;br /&gt;&lt;br /&gt;The available diameters are 2 to 30 mm. The available length is 915mm.
