Golden JET bits
One hole, one bitAtlas Copco has launched a new range of long life wireline bits within the Craelius Super Cutter series. The Golden JET bit is the result of Atlas Copco´s commitment to develop unique products which improve our customers competitiveness.
Higher crown impregnation will logically lead to longer life. The JET design from Craelius diamond bits is a patented in-novative solution with increased impregnation height of the crown, to give extended bit life.
The Golden JET bits reflect our ambition to develop products to improve our customers cost effiency. Each meter we prolong the core production instead of wasting time and money on rod handling, is added value for the customer. We are not there yet – but we are getting closer to ’’One hole, one bit’’.
Production instead of rod handling
JET bit characteristicsnExtremely long life nWide range of rock formations nHigh penetration rates
Our unique solution, with increased impregnation height (currently 16 mm), results in an extremely stable crown.
By reducing the number of waterways, we created wider seg-ments and larger base for stronger adhesion to the bit body. To maintain optimal cooling and cutting transportation, the segments are designed with slots in both outside and inside.
This unique, protected solution gives a long bit life combined with high penetration rate. A combination of the JET design and the range of matrices from the Super Cutter series will outperform any other bit on the market.

SC10 Extremely hard, non-abrasive, fine grain, very competent.
SC9-10 Very hard – extremly hard, slightly abrasive.
SC8-9 Hard – very hard, slightly abrasive.
KS (S++) Hard – very hard, polishing.
SC7-9 Medium hard – very hard, moderately abrasive.
SC6-8 Medium hard – hard, polishing + mixed.
KX Medium hard – hard, polishing + mixed.
SC5-6 Medium soft – hard, abrasive, fractured.
SC5 Medium soft, abrasive, fractured.
SC2 Extremely abrasive, highly fractured.
Impregnated diamond drill bits are designed to perform as grinders. Diamonds are embedded in an infiltred or sintered matrix. The matrix erodes away at the same rate as the dia-monds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock.
The combination of diamonds and matrix determine the per-formance of an impregnated bit. The simultaneous erosion of the matrix and the diamonds makes the bit self sharpening.
The ideal combination of optimal penetration rate and wear resistance matched to achieve the ultimate in drilling economy.
In most geological formations, impregnated bits are more economical to use than surface set bits as they provide ad-ditional benefits:
n Greater resistance to wear in most formations, particularly in fissured and fractured formations.
n Less sensitive to abuse, rough handling and improper use.
DiamondsOnly synthetic diamonds, except for gauge stones, are used in the manufacture of Atlas Copco impregnated bits. The constancy of shape, granular size, and strength make syn-thetic diamonds better than natural stones.
The diamonds are carefully selected by quality and size for the application. Through advanced manufacturing technology an extensive range of drilling requirements can be satisfied.
Continuous control of the processes at each step in the manu-facturing ensures that all bits are of identical quality. This consistent high quality means more drill metres per bit.

Crown heightStandard impregnated drill bits are available with different matrix heights:
n Low (2):6.5 mm, Conventional bits n Standard (3):9.5 mm, Conventional bits and WL bits n Extra high (4):12.5 mm, Wire line bits n Super (5):16.0 mm, Wire line bits
Low and standard height is used for conventional bits where bit life does not effect the number of round trips and when large wear of the bit diameter is anticipated (meaning that extra high matrix cannot be fully utilized).
For wire line bits, Extra or Super matrix height is generally recommended.
ProfilesMost impregnated bits have W-profile.

Excore Surface Set and Impregnated
Reaming ShellsExcore reaming shells are manufactured to withstand difficult drilling conditions and pro-vide long life. Surface set reaming shells in all common DCDMA sizes are a stock item. Im-pregnated reaming shells and reaming shells in full hole profile are also available. Reaming shells are available in industry standard lengths of 15 cm (6”), 25 cm (10”) and 46 cm (18 3/8”). A combination of polycrystalline diamonds (PCD) and natural diamonds are utilized for most standard reaming shells and all heavy duty reaming shells.
Excore Casing and Rod ShoesExcore casing and rod shoes are manufactured to handle a broad range of conditions, from unconsolidated overburden to broken, abrasive formations. Impregnated standard and heavy duty casing shoes are stock items.

Drilling parametersDrilling recommendationsTo select a suitable diamond bit for a given situation, basic information is needed:
n Geology n Type and size of core barrel n Flushing media
The final performance with selected bit depends on following parameters controlled by the operator:
n WOB – weight on bit n ROP – rate of penetration n RPM – revolution per minute n RPI/RPC – revolution per inch/cm n Flushing
Craelius impregnated diamond bits are supplied with recom-mended drilling parameters for best performance.
Sometimes an impregnated drill bit become blunt. Reason could be, difficult drilling conditions, hard formation, wrong drilling parameters, wrong bit type etc.
To sharpen an impregnated bit is a delicate process. If sharp-ening is not correct done, you will loose matrix and bit life. Momentarily increase the WOB by approximately 15-25%, at the same time, slowly reduce water flow to a level not less than what is indicated on the bit sticker. When the bit begins to sharpen, noticed by increase in drill system pressure and lower rotation speed, reduce the WOB and increase water flow to normal value.
Weight on bitWeight on bit (WOB) is not an operation parameter, the value is a result to maintain a constant penetration rate (ROP). Di-amec APC drill adjust WOB automatically for a preset ROP. The value of WOB for a chosen ROP indicates the actual drilling condition. Too high WOB value might cause problem such as:
n Excessive wear on bit n Hole deviation n Damage or wear on core barrel and rods
Please note!Recommended max WOB in the bit sticker is max allowed value to avoid damage. Temporary high WOB may be ap-plied to sharpen the bit. Too low WOB will polish the bit and it will loose its self-sharpening ability.
Penetration ratePenetration rate (ROP) is a very important drilling parameter especially for impregnated bits. The value should be kept constant and set as high as possible. High ROP keeps the bit sharp and return best performance.ROP depends on follow-ing conditions:
n Bit type and size n Capacity of core drill n Formation n Hole depth n Hole deviation n Flushing
Revolution per minuteImpregnated bits should generally be used with high revolu-tion per minute (RPM). Depending on bit diameter, rock condition and machine capacity.
Peripherical speed 2-5 m/s is recommended for impregnated bits. For surface set diamond bits peripherical speed 1-3m/s is recommended.
The RPM diagram gives a rough recommendation for RPM-related to bit type and hole diameter.

Example: A 76 mm diameter hole is to be drilled, the drill rod diameter is 53 mm and the desired flushing water velocity is 40 cm/s. Find the line for the 76 mm hole/53 mm drill rod; then find the velocity 40 cm/s on the curve’s X-axis. Follow the line 76/50 until it bisects the 40 cm/s line, then follow a horizontal line to the left line and read off the water volume = 63 l/min.

Drilling parametersFlushingParticularly for impregnated bits, bit performance is strongly dependent on water flushing. The flushing has three pur-poses: cooling the bit, lubricating the bit and drill string and to lift up the cuttings. Some bit types need a lot of water to perform well, others do not.
For most bit types a reduced amount of water sharpens the bit and reduces bit life, while a lot of water can polish the bit but increase the bit life. This is most valid in hard and polish-ing rock.
Suitable amount of water for each bit type is stated on the sticker for drilling parameters.
The required cutting volume to lift up the cuttings, depends on hole diameter and drill rod size. Required water volume can be calculated in the diagram below.
Always use the higher volume of the values in the dia-gram and recommended on the bit sticker. It is highly recommended to use an accurate flow meter.
Revolution per rate of penetrationRevolution per inch (RPI) or revolution per centimetre (RPC) of advance has been developed as an index to main-tain correct relationship between RPM and ROP.
Today Atlas Copco bits are design to perform with much higher ROP than the index originally was based on. The index should be considered as a starting point.
Index recommendation: RPI 200-250 (RPC 80-100) For recommended RPM 1200 you can expect ROP 6" (15cm) per minute
ROP = RPM/RPI = 1200/200 = 6 (inch/min) ROP = RPM/RPC = 1200/80 = 15 (cm/min)
Please note!Higher ROP Higher RPM Higher flow rate

Super Cutter (SC) range
nLong life, free cutting Extremely high impregnation, skilled engineering and unique production methods combined with high quality components.
n Wide range of applications Just a few matrices cover all rock formations.
n Fast and efficient penetration Unique matrix alloy design, allows worn diamonds to be replaced instantly by new diamonds.
Use recommended drilling parameters and the Super Cut-ter bit will give optimal performance provided the matrix selected is suitable for the actual rock formation.
