Product Features
Seal and Lubrication
Premium HNBR O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Lug Back Enhancement
Carbide inserts are strategically arranged on lug back to improve bit's protection in abrasive formation,which can expend working life of the bit
Replaceable Nozzles Design
Replaceable nozzles with either nail retention or snap ring retention are supplied for the best hydraulics possible
Protection for Cone Shell
A row of carbide inserts is added between the outer row and the back cone rows to trim hole wall and protect cone shell
Shirttail Hard Facing
To ensure greater durability, we have welded carbide layer on shirttail that significantly increases wear resistance in this critical area of the bit
