The main products we can provide: 1.tricone bit(steel tooth and TCI tricone bit) 2.PDC bit(steel body and matrix body PDC bit) 3.rock hole opener for vertical and horizontal directional drilling, rock reamer 4.single tricone cutter 5.other drilling tools(drill rod, mud motor, drag bit, etc)
1.Tighten the bits when screw on. 2.When the bit lower down to the bottom , Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling. 3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay. 4.When drill jammed, withdraw first, should not to force the rig start. 5.Drill could not without water, to ensure that the bit will be too hot. 6.Use the bits in right order , big size first, then small one . 30*40*45 cm 50kg
Steel tooth bits series: Soft formation tooth bits: The soft formations tooth bits are used to drill low compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth. Medium hard formations tooth bits: The medium hard formation tooth bits are used to drill high compressive strength, medium hard formations. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
The steel tricone bit is made of high manganese carbon steel, and our products almost cover all the iadc code, all in good quality and reasonable price. 30*35*40cm 50kg
Product Description: 1. Bit Breakers The Bit Breakers are suitable to make up or break out the drilling bit during the oil well drilling and repairing operations. The Users should be chosen the bit breaker according to the size and model of the drilling bit. Feature:Improve support and retention Advantage:Manage the magnitude cutter loading and bit torque Benefit:Improved bit durability and directional responsiveness Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allow for higher flow rates with minimal increase in pump pressure. 2. Detailed introduction to Bit breaker 1) Bit breaker is mainly used to screw on or off a rock bit to the bottom of drill string. 2) It can also prevent the rock bit from dropping into well hole. 3) The price of it is cheap and the use of it is safety and reliable. 4) It is easy to operate. First, the bit breaker is placed on well hole and then put the rock bit onto it. Turn it to screw on or off the bit by turnplate.

Combined circulation(three side jets and one central jet). 2. Shirttail and leg entering edge hardfacing. 3. Aggressive cutting structure In wooden case. Dimension: 38*34*53 cm
1.Cutting structure this type TCI tricone bits: The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit. 2.Gauge structure this type TCI tricone bits: Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. 3.Bearing structure of this type TCI tricone bits: High precision bearing with two thrust faces. Ball lock the 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. 4.Seal and Lubrication of this type TCI tricone bits: Premium 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 . 5.Product Application this type TCI tricone bits: It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height.
