  • MetalsDepot® - O1 Drill Rod Tool Steel

    O1 drill rod has a higher alloy content and much better toughness than its water-hardening counterpart. O1 drill rod is an all-around general purpose tool steel that exhibits reliable hardening, excellent toughness, and good wear-resistance properties. It is a great replacement for W1 drill rod when those properties are required.
