1 material: diamond
2 suitable for medium to medium hard formations
3 Cutting structure: the durability of premium diamond insert is improved with new formulas and new techniques for insert bit.
4 Guage structure: Multiple guage protethion with trimmers on the heel of cine,tungsten carbide inserts and hard facing on the shirttal increases guage holding capability and bearing life.
5 Seal and lubracation: Premium O-ring,optimal.Seal compression and curred seal structure can enhance the seal performance.The compensator system and advanced grease can greatly increase the lubricaing reliability.
6 Bearing structure: High precision bearing surface inlaid with friction-reducing alloy and the silver-plated.Abrasion insistance and the silver-plated.Abrasion insistance and seizure resistance of the bearing are improved.
7 Production application: it can receive high WOB in the conventional drilling.It is suitable for various formation by cutting structure with different tooth shape,tooth density and tooth exposure hight.
From 1.8 inch (45mm) to 26 inches (660mm)Note: sizes and types that are not shown above can be customized according to specific drilling requirements
