3 Dedicated to being the best We are committed to your superior productivity through interaction and innovation. Atlas Copco Exploration Products continues to set new standards in the design and manufacture of diamond drill bits for the world s exploration industry. As with Atlas Copco drills and in-hole-tools, the company s Hobic bits are the choice of experienced drillers for consistently meeting and exceeding expectations. Hobic is a true blue collar bit. We have incorporated the experiences and on-site requirements of the world s best drillers into the design and development of the Hobic line. Combined with cutting edge metallurgical technology and our ongoing quest to take penetration rates higher, the result is Hobic for the most demanding core drilling conditions anywhere today and into the future. If you re looking for proof of our commitment to continuous improvement, consider that more than ninety percent of the impregnated diamond products in this catalogue are the result of design and technology upgrades that have occurred just in the last two years. Need more proof? Consider this: In South Africa, surface drillers working in platinum formations with Hobic NQ diamond bits exceeded the dream limit of 50 cm/minute (20 in./minute) penetration. In Nevada, a contractor using an Atlas Copco Diamec U8 rig and Hobic Torpedo Technology bit drilled 185 metres (607 feet) in one ten hour shift. In Chile and Peru, Torpedo Technology bits provided exceptionally longer bit life in extremely abrasive rock, averaging 140 metres compared to previous bits that lasted a maximum of 90 metres. Having the best bits in the business is only part of the Hobic story. Atlas Copco s worldwide distribution network ensures the product arrives where and when it is needed. It s what our customers expect, and we deliver. 3
4 Torpedo technology a cut above For more than two decades, Hobic bits have been serving the exploration industries of North and South America. Today, thanks to Torpedo technology, contractors around the world are demanding the kind of results only available from this premium line of diamond products. Torpedo technology features an exclusive matrix design that actually increases the cutting efficiency of each singular segment. Where traditional matrices have caused irregular wear and even premature failures, Torpedo technology s new alloy-based matrices provide increased toughness and control wear so that our premium synthetic diamonds are consistently exposed for optimum penetration. Torpedo technology matrices are available on all seven Hobic crown profiles and each matrix formula is able to drill a broad range of formations. Torpedo technology has succeeded in lowering the bit cost per metre drilled. Its exceptional durability and superior abrasion resistance have proven to increase penetration rates by 30% and extend overall bit life by 60%. Torpedo V design 1 Although many have tried, Hobic s proprietary Torpedo V profile and unique matrix formula are unmatched in the industry. The V-shaped cutting segments and high-speed flushing channels reduce the contact area providing unparalleled penetration rates. Torpedo tough edge 2 To reduce wear caused by high speed flushing, Torpedo bits feature abrasion resistant carbide prisms, strategically placed to resist diametric wear and maintain the correct inner/outer gauge for the life of the bit. Torpedo super bond 3 The secret to the longer life and cutting performance of the Torpedo matrices is a new bonding material. Developed especially for the alloy-based matrices, it comprises nonreactive elements so the matrix can maintain its superior metallurgical properties
5 Hobic surface set Surface set and impregnated reaming shells Hobic 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, but may require longer lead times. 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. 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. Surface set casing shoes are available, but require longer lead times. Rod shoes are available only in an impregnated design. Craelius bits Since 1866, Atlas Copco s Craelius line has pioneered many innovative products in the diamond drilling industry. With over 100 years of experience, Craelius diamond impregnated bits offer an alternative in hard fissured and fractured formations. The full range of complimentary diamond products from Craelius includes the long life, 16 mm Jet Bit. Atlas Copco geotechnical bits Developed in South African drilling conditions, Atlas Copco offers a wide range of specialty bits, designed for non-abrasive to soft and broken abrasive formations. These products are used extensively in geotechnical applications as well as coal exploration. Atlas Copco range of specialty bits: Surface set bits Polycrystalline diamond bits (PCD) Tungsten bits Non-coring bits Large diameter bits 5
6 Hobic 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. ROD SIZE Calculation RPM Penetration rate = RPI/RPC "/min = 150 RPM ,3 cm/min = 59 RPC Bit sizes 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 Hobic 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. 6
