Kingdream Tricone bit
Based on the development of drilling technology and process and changes of the market in China and wordwide, Kingdream recently introduced new product series, which are easy to be selected by customers and specific to normal drilling problems. These products are named based on specific functions of the bit. Original nomenclature are still used for original product series such as HJ and HA series bits.
- Kingdream’s High speed MD bit series is specifically designed for directional, horizontal and horizontal multilateral well driing appications.
- MiniMD slim hole bit series is especialy for improving the durling time and safety of the bit when drilling lower and small diameter section of the deep and ultra-deep wells.
- SMD Ultra-speed motor bit series is specialy developed for using with high speed down hole driling tools such as turbo or screwdrills.
- HardFighter bit (HF hard formation driling bit) series is introduced to the market for meet the requirement of driling deeper formations. in order to achieve longer life and higher ROP of the steel tooth bit for driing upper formations,
- Swifturmn bit (SWT high eficiency steel tooth bit) is developed.
- Air bit (A series bit for air driling applications) series is designed for air drilling
Kingdream Drill Bit Additional Features
C - Center nozzle
Center jet can avoid bit balling, eliminate resorting area of fluid at bottom hole, expedite upwardflow of cuttings and improve ROP. lt is suitable for drilling in soft to medium soft formations withlow compressive strength and high drillability.
D - Diamond inserts on gage protection area
Better drilling performance can be achieved when drilling in the more abrasive directional well and horizontal well by arranging diamond enhanced inserts in head OD.
E - Extended double nozzle
Extended double nozzle can expedite upward flow of cutings and eliminate resorting area of fluidat bottom hole to realize safety and high efficient drilling.
G - Head OD protection
Special inserts are strategically arranged on head OD to effectively reduce head wear in abrasive formation and directional and horizontal wells and extend bit life.
J - Directional jet
Directional jet feature (J) enlarges lateral flow area on bottom hole and is helpful to bottomhole cleaning and increase of ROP, Suitable for soft to medium soft formations of low compressive strength and high drillability.
H - Diamond enhanced inserts
Better drilling perfommance can be achieved when driling in more abrasive, hard and extreme hard formations by arranging diamond enhanced inserts in heel, gage rows and head OD.
X - Convex crested wedge compact
Convex crested wedge compact is with the features of high effectively cutting ability and strong anti-breaking ability, which can increase ROP and improve service life of bit effectively, lt's suitable for formations from medium soft to medium hard.
Y - Conical spherical compact
Main cutters of bit are conical spherical compacts, which are suitable for drilling in hard brittle formations.
K - Hard plastic formation cutting structure
Unique designing parameters and wider insert crest enlarge rock-breaking volume onbottom hole and increase bottom hole coverage.At the same time, shear sliding distance of inserts at bottom hole is made larger and ROP of the bit in hard plastic formation is increased.

Kingdream tricone bit structure features
- High wear resistance and excellent cutting ability of the insert bit are given fully play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows the exposure height and special shaped compacts. For steel tooth bit.the tooth surface is hardfaced with new type of wear resistant material and thus extended working life of the cutting structure while still maintaining high ROP.
- A row of inserts is added between gage row and heel row of HA bit to trim borehole wall and protect cone shell and consequently, the special HAT series bit is formed.
Kingdream Tricone bit
HA/HAT rubber sealed bit with journal bearing
HA/HAT series Kingdream tricone bit adopts rubber seal with joumal bearing, which can sustain higher WOB under normal rotary speed and is suitable for driling informations from very soft to middle hard by properly selecting different cutting structure
Main structure features:
- Joumal bearing. Hardfaced head bearing surface. Inner hole of cone is silver-plated, The load capacity and seizure resistance of the bearing is greatly improved.
- O ring seal is made of the more wear resistance high saturated bunaN with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
- All rubber compensator is used which can limit pressure differentia and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
Kingdream Tricone bit
HJ/HJT metal sealed bit with journal bearing
HJ/HJT series Kingdream tricone bit adopts metal seal with joumal bearing, which can drill stably with higher rotary speed.
Main structure features:
- Metal-face seal journal bearing. New processes of head bearing hardfacing and cone bearing silver plating are used to improve the load capacity,anti-galling ability and stability of the bearing.
- Various shapes of inserts can be equipped on this series of bits including scoop inserts,wedge inserts,conical-sphericalinserts and double spherical inserts, etc. Drilling process &formation and bit are efficient integrated by scientific insertshape selection to realize safety and high efficient drilling.
- A row of inserts is added between gage row and heel row of HJbit to trim borehole wall and protect cone shell, and as a result,HJT series bit is formed.
Kingdream Tricone bit
GA/GAT rubber sealed bit with roller bearing
GA/GAT series Kingdream tricone bit adopts rubber seal with roler bearing, which is the ideal and economical tool for driling appications where middle to low WOB and high RPM are required.
Main structure features:
- Sealed roller bearing structure. With rollers arranged ingrooves recessed in the cone body, the size of the bearing journal is increased, therefore, with the ability of enduring high WOB and applying for high RPM.
- Thrust bearing surfaces are hardfaced and treated with friction reducing technology.
- All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing systemwith good assurance of lubrication.
