  • Drill Rod Tool Steel Products: A2 - O1 - W1 - D2 - S7 -

    Drill Rod. Drill Rod is a type of tool steel round stock that is ground to a tight tolerance. The tight dimensional tolerance eliminates subsequent machining which saves the end-user time and additional machining cost. There are three types of Drill Rod: air-hardening, water-hardening, and oil-hardening.
