Product Description

Product introduction

Rock Bit S-2 Tool Steel balls are designed to work well in very extreme conditions that are common when drilling deep into the ground. The balls provide the strength and toughness that is required to withstand heavy force and the abrasion of pulverized rock. These balls also have unusually good wear characteristics due to the materials hardening capabilities.

Rock Bit S-2 Tool Steel balls are manufactured for bearings that are used in well drilling, oil field drilling and equipment and offshore drilling platforms.

Material: Rock Bit S-2 Tool Steel

Diameter:2mm - 200mm (Professional production line 4.763mm 3/16",7.938mm 5/16" ,9.525mm 3/8"and so on )
