4 More performance - less bits As each Excore diamond bit covers a wider range of applications, fewer bit types than before are needed to do the same job. This makes bit selection much simpler for the driller and reduces the number of bits needed on the job site. It is easier for less experienced drillers to select the optimal bit for the job. This not only improves productivity, but also reduces the risk for failing to meet deadlines for the drilling contractor. The Excore series of new matrices combined with optimized crown profiles have been categorized into three types of drilling applications to simplify the bit selection for the driller. As the Excore bits provide superior performance in a wider range of formations, it becomes easier for the driller to find the best bit for the job, meaning the new range is more forgiving. The Excore bit line is divided into three applications: Application 1 Excore for soft to medium hard, very abrasive to slightly abrasive and very fractured to slightly broken formaions. Application 2 Excore for medium hard to hard, abrasive to slightly abrasive, moder ately fractured to competent for mations. Application 3 Excore for hard to very hard, slight ly abrasive to non abrasive, very com petent formations. Each Excore type is available in various crown designs like the Extended Channel Flush (ECF) for broken to competent formations, the patented Jet profile for fast cutting in competent formations and Face Discharge (FD) design for extremely broken and triple tube applications. Combining these features with different available crown heights, from mm, means there is an Excore for every core drilling application. How to select in three easy steps: Application Step 1 Determine the application by selecting the drilling conditions Application 1 Soft to medium hard rock with abrasive and fractured to competent formations Matrix series 1-4 Application 2 Medium hard to hard rock with slightly abrasive and slightly broken to competent formations Matrix series 5-8 Application 3 Hard to very hard rock with competent formations Matrix series Profile Step 2 Select the appropriate crown profile Extended Channel Flush (ECF): For broken to competent formations Jet profile: For fast cutting in competent formations. Face discharge (FD): For extremely broken and triple tube applications. 3.

5 Excore applications Bit selection chart To simplify bit selection for the driller rock formations have been categorized into three applications. Each application has a series of matrices designed specifically for that type of drilling condition which will provide optimum performance. Application 1 (Green) Soft to medium hard, abrasive and fractured to competent formations. Application 2 (Blue) Medium hard to hard, slightly abrasive, slightly fractured to competent formations Application 3 (Red) Hard to extremely hard, competent formations.

7 Excore drilling parameters RPI/RPC Many factors influence the performance of impregnated bits. In addition to the type of formation being drilled, factors such as hole diameter, depth, ground conditions, type of drill, weight on bit, water flow and RPM all have an impact on performance. The top priority of today s drillers is performance. To achieve optimum drilling production while balancing bit life, a correlation between RPM and penetration rate has been developed for impregnated diamond bits. This parameter is referred to as Rotation per Inch of advance (RPI) or Rotation per centimeter (RPC). This parameter can be utilized as a guideline to increase penetration rates while maintaining reasonable bit life. Water flow Water flow is a critical parameter. Insufficient or excessive water flow can result in poor performance. Size LPM (USGPM) RPM A (4-5) 1650 B (8-10) 1350 N (10-12) 1100 H (13-16) 850 P (20-22) 650 Water flow may vary depending on the specific application and therefore this chart is only to be used as a guideline. Sample Calculation N Size Bits RPM / Penetration rate = RPI (RPC) 1200 / 8" per min = 150 RPI 1200 / 20,3 cm per min = 59 RPC Bit Size RPM Optimum RPM RPI (RPC) A (100) B (79) N (67) H (51) P (40) RPI or RPC = RPM / Penetration rate. This chart has been developed as a guideline for Atlas Copco impregnated diamond bits. Polished bit Often an indication that an impregnated bit has become polished will be a reduction in torque and penetration rate, with an increase in the weight on bit (WOB). Controlling the flow of water can be used as a method to sharpen the bit. To sharpen a bit in the hole, gradually reduce the flow of water while increasing the weight on the bit to strip the bit and expose fresh diamonds. Once the bit has been sharpened increase the flow of water and reduce the WOB as required. 7

Excore reaming shells and casing shoes Excore Surface Set and Impregnated Reaming Shells Excore reaming shells are manufactured to withstand difficult drilling conditions and provide long life.

8 Excore reaming shells and casing shoes Excore Surface Set and Impregnated Reaming Shells Excore reaming shells are manufactured to withstand difficult drilling conditions and provide long life. Surface set reaming shells in all common DCDMA sizes are a stock item. Impregnated 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. Hobic Casing and Rod Shoes Hobic 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. 8

23 A Bit of Excellence An exploration contractor s success is dependent upon the efficiency of his drilling equipment. To meet this demand, Atlas Copco has developed the new Excore diamond bit, which offers the latest in diamond drilling technology. Atlas Copco has combined scientific research and innovative new technology with more than 100 years of field experience to create a diamond bit that will revolutionize mining exploration. Excore is a faster drilling, longer lasting coring bit that performs in a wider range of drilling conditions and formations. This means fewer bits needed on the job site - both in operation and on the shelf and increased productivity throughout the entire operation - from purchasing to retrieving core. Excore from Atlas Copco is a series of diamond drill bits that is in the absolute top range of what is available today a bit that stands for excellence, durability, speed and strength.
