Tool Steel O1 Drill Rod, Oil Hardening
O-1 drill rod round is a non-deforming tool steel ground to a tight tolerance diameter, usually ±0.0005 in (±0.013 mm) which can be hardened by heating it, then quenching it in oil. Tools and dies made from O1 drill rod will have good wearing and abrasive qualities due to the tungsten and higher chromium content, which gives improved wear resistance. It is commonly used to make drill bits, taps, reamers, punches, dowel pins, and shafts.
Hardening O-1 Drill Rod: In a control temperature oven, heat slowly to between 1450-1500°F (788-843°C), and should have a cherry red color. Immediately quench it in oil, inserting it straight into the oil, moving it up an down motion vertically, not an angle. This will prevent the metal from warping. Continue the oil bath until the oil stops bubbling. Then, as soon as possible, move to the tempering part of the process.
Tempering O-1 Drill Rod: Temper your O-1 drill rod by reheating to the desired temperature to relieve the stressescaused by hardening process, and to achieve the hardness needed. The lower the temperature the drill rod is reheated to, the higher the level of hardness remains. Reheat for no less than 1 hour, and up to two hours.
