| Formation |
Hard formation with high compressive strength ,such as limestone,sandstone,dolomite,hard gypsum,marble,etc. |
Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit
Gauge Structure
Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life.
Bearing Structure
High precision journal bearing with two thrust faces,Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and suitable for high rotary speed
