  • Rockwell B Drill Rod - Grainger Industrial Supply

    Rockwell B Drill Rod. A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter.

  • Drill Rod Hardness and Machinability

    Drill Rod Hardness and Machinability. The rods are manufactured of annealed tool steel (O-1, A-2, D-2, H-13, S-7, M-2, or W-1). Then they are cold drawn and (usually) polished. The drill rod hardness is affected by the cold drawing manufacturing process. The hardness is greater for the small diameters as show by the table below.

    2014-9-26u2002·u2002Likes (Received) 54. I use O1 drill rod - oil hardening. You can tap it, but it's noticeably harder to do so than mild steel. Given it's a very fine thread, you don't have as much lee way for oversized holes, but a hole on the larger side will certainly help. Still, I wouldn't be overly concerned about tapping it with only one tap available.

  • Rockwell Hardness Guide

    The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B – A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation.
