But it helps to know that Atlas Copco is determined Golden JET bits are developed and manufactured to make the dream come true. Take the new Golden by Atlas Copco within the Super Cutter range. 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. Golden JET bits

5 Impregnated bits

Impregnated diamond drill bits are designed to perform as The diamonds are carefully selected by quality and size for grinders. Diamonds are embedded in an infiltred or sintered the application. Through advanced manufacturing technology matrix. The matrix erodes away at the same rate as the dia- an extensive range of drilling requirements can be satisfied. monds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. Continuous control of the processes at each step in the manufacturing ensures that all bits are of identical quality. This The combination of diamonds and matrix determine the per- consistent high quality means more drill metres per bit. 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 additional 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.

Diamonds Only 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.

Crown height Standard 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.

Profiles Most impregnated bits have W-profile.

9 TC bits Bits for soil investigations and geotechnical drilling

A range of bits designed especially for soil investigations and geotechnical drilling, but also suitable in some applications for mineral exploration.

Tungsten Carbide (TC) bits Carbide 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 inserts n TC CORBORIT® bits

TC bits with octagonal inserts These 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 octagonal insert

TC Corborit® bits Corborit is another type of tungsten carbide bits manufactured of crushed carbide chips with a granular size of 2-5 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 recov- ery 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.

TC Corborit

10 PDC bits

PDC (Poly-crystalline Diamond Composite) bits PDC bits are an alternative to TC bits and surface set diamond bits, when drilling in non-consolidated and medium hard rock formations.

We offert two types of PDC bits: n Diapax n Tripax

Diapax Bits with brazed round PDC inserts.

Tripax Bits with brazed cubic or triangular PDC inserts embedded Diapax in the matrix. Bits with cubic inserts available with sawtooth profile.

For recommended RPM 1200 you can expect ROP 6" (15cm) per minute Suitable amount of water for each bit type is stated on the sticker for drilling parameters. ROP = RPM/RPI = 1200/200 = 6 (inch/min) ROP = RPM/RPC = 1200/80 = 15 (cm/min) The required cutting volume to lift up the cuttings, depends on hole diameter and drill rod size.

Higher ROP  Higher RPM  Higher flow rate 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.

SC ROCK GROUP ROCK CHARACTERISTICS ROCK TYPE

Soft or medium soft Unmetamorphosed or weakly metamorphosed shales, sandstone and lime- Very abrasive 1 - 4 stone Highly fractured Medium soft Limestone and dolomite. Weathered 5 Abrasive granite and gneiss. Serpentinite and Fractured metaperidotite. Hard Unmetamorphosed or weakly metamorphosed diorite, gabbro peridotite and Abrasive 6 gneiss. Basalt, andesite. Fairly competent Medium hard 7 Moderately abrasive Metabasalt, amphibolite. Metamorphosed diorite and gabbro. Diabase. Competent Hard Quartz rich skarn. Granite and pegmatite. Weakly metamorphosed intermedi- Moderately abrasive 8 ate and acid volcanic. Competent Very hard 9 Slightly abrasive Metamorphosed granitic rock and wuartz quartz rich gneiss.

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 Cut- ter bit will give optimal performance provided the matrix selected is suitable for the actual rock formation.
