FAQ: 1.Q:What kind of packages could you make? A: Ply-wood case (Wooden case free of fumigation); Steel boxes,Packing can be customized according to customers' requirements. 
2.What is your price quality services advantages? We are 100% real factory,so the best price and quality for you.And we can provide Usage and welding method of tricone Hard rock cutters. Hope to creat value for you.Welcome to make a video-call to inspect our factory with us by wechat/whatsapp. we have already built an outstanding technological innovative R&D department for guiding urdrilling work and technical support for after sales, also could offer the drilling feedbacks for your reference. 3.Q: How about the delivery terms? Payment: T/T, L/C, Western Union, Paypal, 30% deposit in advance and rest before delivery. Min. order quantity: 1 piece. Transportation: By DHL/TNT/Fedex express, air, sea, train. 
Advantages of YINHAI Single Roller Cones: Cutting Structure To reinforce the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts and new pressing and welding techniques. Gauge Structure The multiple heel position with gauge trimming inserts on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection. 
Bearing Structure High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed. Seal and Lubrication The advanced rubber sealed journal bearing design. The energizer and back-up ring will support the pushing force to make the seal tightly contact. In the drilling, the rubber seals are relevant moving, and the energizers are static. This will increase the bearing seal reliability and durability. The compensation system and the high quality bit grease can limit pressure in different formation, and greatly increase the lubrication reliability. YINHAI production scope: We are manufacturer of tricone bits, PDC bits, Piling foundation single cones/ rock reamers. Our bits based on high-tech skills and designs are used in explitation of natural gas, crude oil, water well, geological exploration, HDD drilling and piling foundation. There are technical research team, production management team and professional sales team in our company to serve our customers. . Such as Tricone bit, PDC bit, cones, Roller bit, single roller cone, Diamond Core bit, Bi-center bit, hammer bits, drag bits, Hole opener,PDC reamer, HDD vertical reamer, rock reamer and other accessories such as subs, nozzles,adapters, bit breakers,etc.
