Manufactured with superior quality steel, advance technologies, designed for us with compressed air or fluid circulation systems. Open bearing and Sealed bearings available Regular and Jet circulation available. Various styles covering all IADC code numbers for drilling different kinds of rock formations, from soft, medium soft, medium hard to hard, very hard formations. 1

5 Tricone Bits for mining well drilling KX series tricone rock bit for mining is tooth inserted bits with compressive air bearing and slag pipe. The series bit has adopted tooth spacing arrangement optimizing, gale room, convex roller, gage protection on the structure. The main assembly parts of bearing system are roller-steel ball-second thrust bearing-roller-first thrust bearing. Bearing surface is applied with wear buttons (extra reinforced). The series bit has advantages of high efficient hole boring, reliably working, and is widely used for metal and nonferrous mine exploitation.

6 Tricone Rock Bits For Oil Well and Deep Water Well Drilling Including TCI tricone rock bit and Mill Tooth tricone bit 1) TCI Tricone Rock Bits with sealed bearings The Main Structure Features: The series of tricone rock bits for oil well and deep water well drilling is inserts tooth jet bit with sealed journal oil bearings. Through optimized design, the tooth spacing arrangement of cone is reasonable, the tooth shapes and height are designed differently in accordance with various kinds of rock formations, and gage protection is better. The bearing is with wear buttons (extra reinforced) and under silver coated, thus improving the loading capacity and seizure resistance, and prolonging the bit working life. The series of bit is widely used for oil and natural gas field s drilling and geological exploitation. For using the series of bits, users can gain high drilling efficiency. 2) Steel Tooth Tricone Rock Bits with sealed bearings The Main Structure Features: The series of tricone rock bits for oil well drilling is steel tooth bits with sealed journal oil bearing The tooth surface is welded and applied with tungsten carbide powder coat and optimized tooth spacing arrangement. The bearing system can adapt high rotary rate. Drilling in the adaptable rock formation, the bit can obtain high PRM, long working life and reliable working. 3

33 WEAR BLOCKS 30

34 Our wear Blocks combine a number of metallurgical properties into one unique wear resistant material which today has been widely used in most abrasive wear applications. Our wear block is an extremely hard laminated bi-metallic, wear resistant composite, which has a nominal hardness of 700 BHN (HRC 63) minimum. It is produced by combining a highly alloyed chromium-molybdenum white iron and metallurgically bonding it to a mild steel backing plate. The bonding possesses high shear strength of over 200 MPa and will not separate. The alloy s microstructure is made up of primary and secondary chromium carbides which are supported by a hard, finely dispersed Martenstic matrix. The hardness of alloy provides maximum abrasion resistance, while the steel backing plate acts as a means of absorbing high impacts and allows easy fitting and use. Typical applications of wear blocks include Excavator Buckets, Loader Buckets, Dragline Buckets, Face Shovel Buckets, Spider Arm Guards on Crushers, Discharge Chutes, Rock Boxes, Grizzly Bars on Feeders, Shredder and Grinding Mills, Sugar Cane Knife Edges, Adaptor/Attachment Protection, Dredging Equipment, Screen Feed Distribution and Fee Hopper Wear Areas. Wear blocks have been examined and tested for grade, quality, chemical analysis and hardness which guarantee high abrasion and impact resistance. Facts about wear blocks for wear protection: Alloy hardness of HBN700 (HRC 63) for long life Additional carbides of 1500 HV maximize resistance to abrasion Circular and dome design minimizes effects of impact, resulting in less chance of loss Easy to position for effective wear resistance Proven in mining and construction bucket applications Wear blocks are available in any sizes and shape customer wants.the most common ones are: chocky blocks shaped or standard wear bars wear buttons wear donuts shredder/grinder tips cane knife edges boomerangs wear plates wafer strips skid bars 31

35 Chocky Bars Our chocky wear bars were first in the market about 7 years ago and had been well proved in US and Australia market. Our chocky bars are easy to use. There is no pre-heating or post heating required when welding into place. They are easy to form and weld onto inner and outer contoured surfaces. The versatility of Chocs allows unique layouts to be created on equipment to reduce the effects of abrasion. The backing plate can be supplied with grooves to aid in the forming, bending and cutting of the block. The unique, formable design of Chocs offers effective protection on sliding abrasion in high wear areas for a wide range of applications on fixed and mobile plant equipment including: Wear bars for Buckets Chute Liners Crusher Liners Road planners Rock box ledges Hammer Tips Part No. Type Size Dimension Weight A B C D E F G (kgs) CB *25*23mm CB *25*23mm CB *40*23mm CB *40*23mm CB *50*23mm CB *50*23mm CB *65*23mm CB *65*23mm CB *80*23mm CB *80*23mm CB *90*23mm CB *90*23mm CB *100*23mm CB *100*23mm CB *130*23mm CB *130*23mm CB *150*23mm CB *150*23mm

37 Shaped Wear Bars Our shaped wear bars available in different shapes to suit specific applications. They can be used to replace conventional expensive hard facing and preparation, such as bucket lips, edges for bucket wheels and loaders as well as screens and crates in mineral processing and handling. Shaped bars offer superior wear life, edge and shape retention and are far more cost effective than conventional hard facing and cut lip protectors or shapes. Shaped bars are ideal for prevention of gouging wear that normally occurs in such locations and thus allow the bucket or machine to run longer and require far less down time for maintenance Part No. Type Size Dimension Weight A B C D E F G (kgs) SB *20*30mm SB *25*35mm SB *25*35mm SB *16*29mm SB *40*70mm SB *25*59mm SB *25*59mm SB *40*90mm SB *25*50mm SB *25*50mm Wear Buttons Our wear buttons are designed specifically for easy and adaptive installation onto a wide range of wear problem areas.

43 Core Barrels Our core barrels include wireline, TT, T2, T6, B, Q series core barrels. We also provide core barrel parts such as core lifters, core lifter cases and locking couplings. This kind of core drill strictly complies with the international standards. Core drilling tools can lift core from drill rods. During this process, picking up coring system is not necessary. Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench are all belong to drill tools. Features of Core Barrels 1) High penetration rate and high drilling efficiency. 2) High core recovery rate. 3) Long bit life and lower labor intensity. 4) Adopt abrasion resistant material. TT Series Core Barrel Ultra-thin walled double tube core barrels, hole diameters 46 and 56 mm. Very thin cutting face allows very rapid rate of penetration through hard formations.

Wireline Core Barrel Wireline core barrel and overshot in sizes A, B, N, H and P. Used for deep mineral exploration. Inner tube is retractable on the wireline, eliminating the need for rod tripping. 40

44 Reaming Shells Website: Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used. Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use. We can produce reaming shells with 6", 10" and 18" length. Features of Reaming Shells 1) Acts as a stabilizer for drill bit. 2) Be set with natural or synthetic diamond. Our reaming shells enjoy the best quality and most special design in the industry. With several different types, we try our best to satisfy any of your requirements.
