1.Medium soft with low compressive strength and harder abrasive stringers
2.Sealed and gage protection journal bearing


Product Description:

Thesetipped tricone rock bits are used to drill Medium soft with lowcompressive strength and harder abrasive stringers, such as hard shale,hard gypsolyte, soft limestone, sandstone and dolomite withstringers,etc.

1. Tungsten carbide insert tooth, sealed and gageprotection journal bearing,hardfaced head bearing surface. cone bearinginlaid with friction reducing alloy and then silver plated. the loadcapacity and seizure resistance of the bearing is greatly improved

2.O-ring seal is made of the more wear resistance high saturated buna-Nwith the section and precissely designed sealing flange in the conesealing area increased the reliability of the seal.
3.The bit bearing is ball which can be applied to high rotary speed drilling.
4.All rubber compensator is used which can provides the bearing system with good assurance of lubrication

5.New type of grease that can sustain high temperature up to 250C is utilized.

6.Highwear resistance and excellent cutting ability of the insert bit aregiven full play by using carbide compacts of high strength and hightouhness in combination with optimized comjpact numbers and rows, theexposure height and special shaped compacts.
7.Meet strictly of API standard

8.Manufacturer of TCI tricone bits, steel tooth tricone bits and PDC bits

9.High quality, reasonable price and best service.

10.Delivery on time

11.Good feedback of the clients

12.Be used for water well, oil field, underground, construction, geothermal well,etc
