2021-6-2 · The Rockwell hardness is a scale based on the indentation hardness of different materials. Different values have varying letter/digit codes based on their level of hardness. As we’ve mentioned before, we manufacture drill rods out of annealed tool steel, which has a Rockwell hardness ranging from 96Rb to 110Rb.
