A bit close to the dreamOne hole, one bit. That´s the dream of every core driller who´s ever had to lift a heavy drillstring out of a deep hole to change a worn out bit.

But it helps to know that Atlas Copco is determined to make the dream come true. Take the new Golden JET bit for example. With a 16 mm high matrix it outlives all other diamond core drilling bits on the market. That means more time in the hole, less manual work and reduced costs.

With Golden JET bits you will boost your productiv-ity and take another step closer to the dream. One hole, one bit.

Golden JET bits are developed and manufactured by Atlas Copco within the Super Cutter range.

Golden JET bits

One hole, one bitAtlas Copco has launched a new range of long life wire line 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 innovative 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 characteristicsn Extremely long lifen Wide range of rock formationsn High 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 segments 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.

INREASING

MATRIX

HARDNESS

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 diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock.

The combination of diamonds and matrix deter-mine the performance 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 additional benefits:

n Greater resistance to wear in most formations, particularly in fissured and fractured formations.

n Less sensitive to abuse, rough handling and im-proper 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 synthetic 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 manufacturing ensures that all bits are of identical quality. This consistent high quality means more drill metres per bit.

Surface set bits

Atlas Copco surface set bits are manufactured to the highest standards in the industry for the ultimate in drilling performance.

Atlas Copco surface set bits have proven to have a high penetration rate, long service life, and best adaptability to changing formations. The diamonds in these bits are arranged in patterns developed from many years of practical field experience. The patterns vary according to the size of the stones used. The patterns are important for the service life and penetration rate of the bit.

The diamonds used are imbedded in a hard matrix with high resistance to erosion.

MatrixSurface set bits are manufactured using a universal hard type of matrix for all formations.

Semi-round

Multi-step

Two wide step (face discharge)

Concave profile (Non-coring)

Diamond qualityThe standard range of natural diamonds for surface set bits is chosen in a special allround grade with special quality. The quality includes selected and processed diamonds with a highly polished surface. These stones have a high impact resistance and may be considered as an universal type. Recommended for soft to medium hard formations.

Diamond sizes (spc – stones per carat)As a general rule; the softer formation, the larger the diamonds used i.e. 20 to 2� spc. In hard formation, smaller diamonds �0 to �0 spc are typical.

Atlas Copco standard diamond sizes are:20/2� and �0/�� spc1 carat = Diamond weight of 0.2 gDiamond content is measured in carat (CRT).

Other diamond qualities and sizes on request.

ProfilesSurface set drill bits are available in different profiles to obtain optimal drilling performance.

Standard profiles for surface set core bits:

n Semi-roundn Multi-stepn Two wide step (face discharge)n Surface setn Non-coring bits with concave profile.

Shells and casing

Reaming shellsReaming shells are placed behind the drill bit on the core barrel to maintain the correct hole diameter and stabilize the core barrel.

A reaming shell has to be replaced when its diameter becomes less than the diameter of the new bit. In this way only the very last part of the hole has to be reamed when a new bit is inserted. A reaming shell also helps to stabilize the core barrel. Reaming shells are available for all types of core barrels and drill bits.

Surface set reaming shellsStandard Atlas Copco surface set reaming shell set with specially selected diamonds and PDC pins. Well designed waterways, reinforced with PDC pins, facilitate effective flushing and contribute to long service life and good drilling economy for both reaming shells and drill bits.

Reaming shells are avialable in different designs:

n 10" Double ring reaming shell available only for BQ, NQ, HQ (need inner tube adjustment).

n FH special heavy duty design for long life with extra stabilization.

n STD (Standard design).

Casing shoesAtlas Copco manufactures a comprehensive range of diamond and tungsten carbide (Corborit) casing shoes for standard drilling or positioning casing tubes into drill holes.

Casing shoes have cutting segments on the front and exterior, while the interior is smooth. The inner diameter of the casing shoe is sufficiently large to permit free passage of drill bits and core barrels in corresponding sizes.

Atlas Copco manufactures a comprehensive range of diamond and tungsten carbide set casing shoes for standard metric and DCDMA casing sizes.

n Impregnated casing shoe bits are manufactured with very hard matrix.

Tungsten Carbide (TC) bitsCarbide bits are normally used for coring in softer rock formations, overburden drilling, and cleaning of drill holes.

Atlas Copco manufactures two different types of tungsten carbide bits :

n TC bits with octagonal insertsn TC CORBORIT® bits

TC bits with octagonal insertsThese bits have octagonal tungsten carbide inserts what are ground at an angle of 10° to form the cutting edges. The quality of the tungsten carbide chosen has been specially developed for rotary drilling to give high wear resistance. The carbide inserts can be reground.

TC CORBORIT® bitsCORBORIT® is another type of tungsten carbide bits manufactured of crushed carbide chips with a granular size of 2-� mm, mixed with a special alloy.

CORBORIT® bits have considerably more cutting edges than standard TC bits and are recommended in medium to medium hard sedimentary formations.

CORBORIT® bits cause less vibration and offer better core recovery than standard TC bits.

All TC bits can be used in clean-out operations, e.g. for the removal of steel fragments from a drill hole.

Drilling parameters

Drilling recommendationsTo select a suitable diamond bit for a given situation, basic information is needed:

n Geologyn Type and size of core barreln 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 penetrationn RPM – revolution per minute n RPI/RPC – revolution per inch/cm n Flushing

Craelius impregnated diamond bits are supplied with recommended drilling parameters for best performance.

Sometime 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 sharpening is not correct done, you will loose matrix and bit life. Momentarily increase the WOB by approximately 1�-2�%, 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.

WOB – Weight on bitWOB is not an operation parameter, the value is a result to maintain a constant penetration rate (ROP). Diamec 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 bitn Hole deviationn 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 applied to sharpen the bit. Too low WOB will polish the bit and it will loose its self-sharpening ability.

ROP – Penetration rateROP 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 following conditions:

n Bit type and sizen Capacity of core drilln Formationn Hole depthn Hole deviationn Flushing

RPM – Revolution per minuteImpregnated bits should generally be used with high RPM. Depending on bit diameter, rock condition and machine capacity.

Peripherical speed 2-� m/s is recommended for impregnated bits. For surface set diamond bits peripherical speed 1-�m/s is recommended.

The diagram below gives a rough recommendation for RPM related to bit type and hole diameter.

Water velocities and water quantities for various hole diameters.

Example: A 76 mm diameter hole is to be drilled, the drill rod diameter is �� mm and the desired flushing water velocity is 40 cm/s. Find the line for the 76 mm hole/�� mm drill rod; then find the velocity 40 cm/s on the curve’s X-axis. Follow the line 76/�0 until it bisects the 40 cm/s line, then follow a horizontal line to the left line and read off the water volume = 6� l/min.

Drilling parameters

FlushingParticularly for impregnated bits, bit performance is strongly dependent on water flushing. The flushing has three purposes: 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 polishing 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 diagram and recommended on the bit sticker. It is highly recommended to use an accurate flow meter.

RPI, RPC – Revolution per rate of penetrationRevolution per inch or centimetre of advance has been developed as an index to maintain 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 200-2�0 (RPC 80-100)For recommended RPM 1200 you can expect ROP 6" (1�cm) per minute

ROP = RPM/RPI = 1200/200 = 6 (inch/min)ROP = RPM/RPC = 1200/80 = 15 (cm/min)

GeneralHigher ROP Higher RPM Higher flow rate

Super cutter (SC) range

n Long 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 Cutter bit will give optimal performance provided the matrix selected is suitable for the actual rock formation.

’’SUPER CUTTER’’ NEW CLASSIFICATION SYSTEM SC ROCK GROUP ROCK CHARACTERISTICS ROCK TYPE

The rock formation characteristics are organized in groups 1-10. Each group iden-tifies a certain rock type. Our new Super Cutters are identified with an applicable rock group number combination instead of just a matrix name.

1 - 4Soft or medium soft

Very abrasive

Highly fractured

Unmetamorphosed or weakly metamor-phosed shales, sandstone and limestone

5Medium soft

Abrasive

Fractured

Limestone and dolomite. Weathered granite and gneiss. Serpentinite and metaperidotite.

6Hard

Abrasive

Fairly competent

Unmetamorphosed or weakly metamor-phosed diorite, gabbro peridotite and gneiss. Basalt, andesite.

7Medium hard

Moderately abrasive

Competent

Metabasalt, amphibolite. Metamorphosed diorite and gabbro. Diabase.

8Hard

Moderately abrasive

Competent

Quartz rich skarn. Granite and pegmatite. Weakly metamorphosed intermediate and acid volcanic.

9Very hard

Slightly abrasive

Very competent

Metamorphosed granitic rock and wuartz quartz rich gneiss.

10

Extremely hard

Non-abrasive

Fine grain

Very competent

Chert and jasperite. Quartzite. Highly meta-morphosed acid volcanic.
