Tungsten Carbide Drill Bucket 8.5 Inch Single Roller Cone Bit For Core Barrel
drill bucket Tungsten Carbide 8.5 inch single roller cone bit for core barrel
Product Feature:
1.The reaming bit consists mainly of four or more cones. The main cutting teeth are new wear-resistant alloys for tungsten carbide inserts and steel teeth. The new formula and the new process of high-quality tungsten carbide teeth improve the service life of the reaming drill. The guide is a cone drill bit or a scraper drill bit.
2.The bearing seal uses high-performance O-ring seal or metal seal bearing and special grease for imported drill bit.
3.Special inserts are placed on the outer diameter of the head to reduce the wear of the head during the formation of abrasives in directional and horizontal wells, prolonging the life of the drill.
4.Replacing Cutters and Cutting Cost-On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit.
Core Barrel with roller bits is used in very strong rock formations(compressive strength >100Mpa).
