The steel type is AISI M-2 high-speed tool steel, annealed for easier machining. It has uniform machining properties and consistent response to heat treatment through carefully controlled chemical analysis.TRM-2 is a tungsten-molybdenum high-speed steel. It has a wider heat treat range than most of the high-speed steels, and has a resistance to decarburization. It offers an excellent combination of good red hardness, toughness and wear resistance.Identification of each production lot is maintained, and a certified chemical analysis can be provided upon your request.The drill rod ends are saw-cut and chamfered or deburred when the diameter is 3/8" 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 orange for easier identification of the steel type.The Diameter |D| tolerance is ±.0003" for rod diameters less than .124, ±.0005" for diameters .125-.499, and ±.001" for diameters of .500 inches and greater. The Length |L| tolerance is +.125/-.000.The available diameters are 1/16 to 1-1/2 inches. The available length is 36 inches. Please contact us if you need a different size, or if you need us to make any alterations.DELIVERY TIME: Normally in stock and ships the next business day.SHIPS FROM: Precision Marshall products are sent directly to you from the warehouses in Bolingbrook, IL; Hartford, CT; Euless, TX; or Santa Fe Springs, CA.MINIMUM ORDER: None.HEAT TREATMENT: Warm slightly before charging into furnace, which should be operating at 1350-1500°F. After thorough preheating, transfer to hardening furnace at 2175-2225°F, depending on the tool size and degree of hardening required for application. Cool in air, oil or a molten salt bath operating at 1000-1100°F. In case of oil quenching, it is usually good practice to interrupt the quench by removing the tool after it has reached about 1000°F, and allow the cooling to continue in still air. Tools should be allowed to cool to 150°F or when they can be held by the bare hand, then TEMPERED IMMEDIATELY. The tempering temperature may be varied according to the desired hardness, but it is usually in the range of 1000-1100°F. Double tempering is ALWAYS RECOMMENDED. TEMPERING DATA:
