AISI S-2 Tool Steel Balls

Tool Steel AISI S-2 Rockbit Balls possess the strength and toughness that is required to withstand heavy force and the abrasion of pulverized rock. The steel has been hardened to withstand the heavy loads and abrasive conditions associated with drilling into the ground. The S-2 Rockbit Balls are wear resistant associated with the most extreme conditions.
