5/8 S412 Mining Rock Bit Operation Instructions

Brief Introduction:

Utilizes carbide compacts of high strength and high toughness for increased impact breakage High precision heat-treated bearing surface to increase the bearing capacity and service life. The thrust bearing utilizes advanced material with excellent hardness and good wear resistance that can further increase the bearing life.

Uses and Applicable Ranges of the Bit

Uses: Applicable for open coal mine, iron ore, etc.

ApplicableRanges: Designed to drill soft low compressive strength and high drill ability formation such as shale, soft limestone, soft sandstone, gravel clay, soft dolomite, halite and coal bed. Applicable for open coal mine, iron ore ,etc.
