6 MORE PERFORMANCE - LESS BITS As each of our core drilling bit covers a wider range of applications, fewer bit types than before are needed which translates to a reduction in inventory. 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 Epiroc series of matrices combined with optimized crown profiles have been categorized into three types of drilling applications to simplify the bit selection for the driller. As our 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. Each matrix 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 (exfd) design for extremely broken and Triple tube applications. Combining these features with different available crown heights, from mm, means there is a bit for every core drilling application. All core drilling bits are divided into three applications: Application 1 For soft to medium hard, very abrasive to slightly abrasive and very fractured to slightly broken formations. Application 2 For medium hard to hard, abrasive to slightly abrasive, moderately fractured to competent formations. Application 3 For hard to very hard, slightly abrasive to nonabrasive, very competent formations. How to select in three easy steps: 1. 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. Rock groups 1-4 APPLICATION 2 Medium hard to hard rock with slightly abrasive and slightly broken to competent formations. Rock groups 5-8 APPLICATION 3 Hard to very hard rock with competent formations. Rock groups 9-10 Standard 2. PROFILE Extended channel flush (ECF): For broken to competent formations. Jet profile/v torpedo: For fast cutting in competent formations, non-abrasive. Face discharge (exfd): For extremely broken and Triple tube applications. STEP 2 Select the appropriate crown profile Specialized CFF/CF: Small/thin wall diameters in conventional systems TT/LTK For broad range of formations. Taper: Used in hole wedging operations to ream wedged hole after pilot bit. Sand: Suitable for competent to extremely broken or clay, clay/sand, mixed formations, double tube applications. 3.

9 Recommendation RECOMMENDED DRILLING PARAMETERS The following information will assist you with proper bit selection or testing according to ground conditions. 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. 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 Epiroc 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. Water flow Water flow is a critical parameter. Insufficient or excessive water flow can result in poor performance. Size LPM (GPM) 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. Each diamond impregnated bit is delivered with recommended application and drilling parameters engraved on its body specific for the bit.

10 IMPREGNATED BITS CROWN PROFILES Standard crown profiles Extended channel flushing (ECF) Standard profile - general purpose design. Suitable for mixed formations containing broken and competent zones. Suitable for a broad range of formations. Face discharge (exfd) Designed to minimize washing of core sample. Suitable for broken/granular formations. exfd stand for "excellent" FD where all flushing medium is directed to the flushing holes. V JET High performance free cutting bit. High productivity. Suitable for hard/competent formations. Suitable for non-abrasive formations. JET26 ECF/JET/JET26 /V/CF/CFF Profiles water flow Coring bit 2. Core lifter case 3. Core lifter 4. Stop ring 5. Reaming Shell Core sample Face Discharge (exfd) Profiles water flow There is a broad range of different coring bit crown profiles available and designed for specific rock conditions and drillers expectations. In medium hard to extremely hard formations when rock is competent or moderately fractured ECF/JET/JET26/V/ CF/CFF profiles are recommended (JET/ JET26/V to increase penetration rate compare to ECF). Drilling fluid in that type of bits is directed towards core sample (7) when passing through gap between core lifter case (2) and coring bit (1). This creates jet like stream which cleans hard rock sample from any cuttings before the sample smoothly slips inside core lifter case (2) and inner tube (6). Although when drilling in soft and/or extremely broken or even unconsolidated formations that jet stream can deteriorate core sample by washing out loose or very soft parts of it. To minimize it Face Discharge (exfd) profile was designed. Contac between drilling fluid and core sample is reduced and the fluid is directed into flushing channels inside bit body. Remember to reduce gap between core lifter case (2) and the bit (1) to minimum, just to prevent inner tube from rotating during drilling, to force fluid to flow through those channels.

11 IMPREGNATED BITS CROWN PROFILES Specialized crown profiles CFF CF Standard profile for small/thin wall diameters in conventional systems TT/LTK. Water way depth needs to be adjusted during drilling using metal file for better flushing control (CFF). Suitable for broad range of formations. Taper Profile used in hole wedging (directional drilling) operations to ream wedged hole after pilot bit. Sand Suitable for competent to extremely broken or clay, clay/sand mixed formations. To improve core recovery in soft/ broken or loose zones. Alternative for the exfd profile when the exfd flushing holes tend to clogg. Face Discharge (exfd) Profiles water flow SAND Profiles water flow Coring bit 2. Core lifter case 3. Core lifter 4. Stop ring 5. Reaming shell Core sample In certain ground conditions like sandy, clay or fine grain unconsolidated formations even Face Discharge (exfd) profiles face challenges to workproperly. In such ground sometimes is hard to keep flushing channels open as they tend to clog which results in reduced bit cooling and borehole cleaning from cuttings which obviously leads to reduced bit life. Same situation may happen when very thick mud is used as drilling fluid. SAND profile has been designed to overcome such situations. Large and deep internal flushing channels are machined in bit (1) body to provide more space for pumping thick mud and keep them clean. Although contact between core sample (7) and flushing fluid is increased compare to Face Discharge (exfd) profile, drilling fluid flows along core sample not towards it as in ECF/JET/JET26/V/CF/CFF profiles. That minimizes wash out effect for core sample (7). Remember to reduce gap between core lifter case (2) and the bit (1) to minimum, just to prevent inner tube from rotating during drilling, to direct drilling fluid along core sample (7). 11

13 RS++ REAMING SHELLS RS++ line of reaming shells Introducing our new RS++ reaming shell Longer life then any other shell Epiroc introduces an all new RS++ reaming shell boosting the number of meters drilled while keeping straighter boreholes. The incorporation of the new matrix into the RS++ provides improved wear resistance. TSP pins + SupraSpherical technology for exceptional life span + Wear indicator for easy wear monitoring Wear indicator Natural diamonds SupraSphericals dynamic protection Wear indicator no gauge checks SupraSpherical technology RS++ features a reinforced diamond ring surface using natural diamonds and a unique SupraSpherical technology provides dynamic protection of the surface. Our new RS++ delivers outstanding results - the combination of natural diamonds and SupraSpherical technology clearly delivers advanced resistance to wear onto the entire surface of diamond ring. All RS++ reaming shells have leading edge of diamond ring reinforced with large thermally-stable Polycrystalline (TSP) diamond pins for better wear pattern control and to maximize diamond volume in high wear zones. Wear indicator Also, new RS++ features patent pending wear indicator bars to identify how much life is remaining. This helps to maintain better control of the borehole OD. The wear indicator gradually wears away over time, and when it disappears, that is the indication that the reaming shell needs to be replaced, see Figure 1. RS++ reaming shell is available in all sizes. 13

14 REAMING SHELLS Surface set reaming shells Epiroc 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 body profile (recommended for very abrasive ground) are also available. Reaming shells are available in industry standard lengths of 15 cm (1-ring /6 ), 25 cm (2-ring/10 ) and 46 cm (3-ring/18 3/8 ). Both 2 and 3 ring type are optional to increase core barrel stabilization when hole deviation needs to be minimized. It extends shell life at the same time. For those options inner tube has to be installed to compensate lenght difference between outer and inner tube. A combination of Polycrystalline Diamonds (PCD) and natural diamonds are utilized for most standard reaming shells and all geavy duty reaming shells.

15 JET26 HIGH CROWN DESIGN One hole one bit Yes, it s true with JET26. One hole one bit. This ideal concept is much more realistic today with the new profile. Use it in competent and non-abrasive/ slightly abrasive formations and be amazed with the performance. The standard JET crown profile now comes with an extended crown height of 26 mm. The JET26 has been modified to provide an extremely robust 26 mm design which prevents crown segments from snapping off in the hole. The 26 mm crown extends JET bit life significantly to drill to much greater depths compared to our JET and Torpedo V 13 mm or 16 mm core drilling bits wich are known for high penetration rates. The Jet26 profile continues drilling without or less rod tripping and tooling changes. The JET26 bit is available in selected sizes and matrices. JET26 design The JET26 patented design provides fast penetration rate. Long robust segments. Half channels for efficient cooling. Chamfer to reduce torque and water pressure. 15

Standard 6" reaming shell above bit, locking coupling & standard 6" reaming shell in the middle of core barrel between two 1,5 m (5') or 3 m (10') outer tubes stabilize core barrel in best possible way. To modify 3 m (10') or 6 m (20') core barrel, standard 6" reaming shell together with inner tube coupling needs to be placed between standard 1,5 m (5') or 3 m (10') outer tubes. To compensate this additional reaming shell length, inner tube coupling needs to be installed between 1,5 m (5') or 3 m (10') standard inner tubes. The only exception is for NO2 size, where inner tube should be placed between head assembly and standard inner tube. coupling Outer tube Stabilizer Reaming shell Core lifter case Core lifter Core drilling bit couplings to compensate lenght of 6" long core barrel stabilizing reaming shell Item AOTW inner tube coupling - Stabilizing Shell compensation BO inner tube coupling - Stabilizing Shell compensation BOTW inner tube coupling - Stabilizing Shell compensation NO inner tube coupling - Stabilizing Shell compensation NO2 - Stabilizing Shell compensation NTW inner tube coupling - Stabilizing Shell compensation HO inner tube coupling - Stabilizing Shell compensation PO inner tube coupling - Stabilizing Shell compensation
