Thewellbeing of any person coming into contact with ourequipment is paramount. Therefore, we strive to identify and assess potential risk factors that could threatenthe health of you and your employees.All of the products in this catalogue are designedto meet safety requirements. Those responsible forequipment and parts installation must take care toensure that all necessary steps have been taken tosatisfy performance and safety requirements. Thisincludes making sure that any applicable laws, regulations, codes and standards are followed.BE AWARE OF ALL SAFETY PROCEDURESWe ask that you start by obeying all instructions given.Never work under an unsupported roof or close topotential “pinch” areas. Beware of the potential hazardsof a loose roof and ribs, and scale down roof and ribsprior to bolting. It is important to bolt early in the miningprocess – as soon as is safely and practically possible.Safe work procedures should incorporate inspectionBefore the machine operates, and also through regularmonitoring based upon mining conditions, safety2Sandvik Mining ROTARY DRILLING BITS AND DRILL STRING TOOLSand hazard management systems. Workers shouldbe provided with safety information, instruction andtraining on transportation, installation, operational careand disposal of drilling tools. and to produce comprehensive manuals on the safe and effective use of ourproducts.DRESS RIGHT FROM HEAD TO TOE(PPE) at all times.

WHATEVER YOUR’RE DRILLINGWE HAVE THE BIT FOR THE JOBSANDVIK BITS BUILT FOR ROCK BREAKINGChoosing the correct drill bit is fundamental to successful and economical drilling. Important factors toconsider include the rock compressive strength, abrasiveness, homogeneity, the desired penetration rate,the capabilities and characteristics of the drill rig, andprevious drilling experience at the mine.SANDVIK ROLLER CONE BITS EXCEED THE LIMITSSandvik roller cone bits are optimized for service life atthe maximum possible penetration rate for the drillingconditions. Carbide grade, shape & size, and cuttingstructure density are selected to achieve the balancebetween productivity and bit life. There is never a compromise on quality. To achieve long life, the bearingsmust withstand the high axial and radial forces that aregenerated during drilling. The bearing design, geometryand material selection are critical factors that go into thedevelopment of new bits.PERFORMANCE FOR APPLICATION EXCELLENCESuperior air-cooled bearing performance is achievedfrom a bearing design that has advanced metallurgy,optimized proportioning of components and geometry.The RR221 air bearing bit range is powered by technology that continues to evolve to meet the demandsof the surface mining industry. Enhancements includeimproved surface finishes, balanced radial and axialbearing loading, and optimized air flow for maximizedcooling.Drill bits operate in an extremely tough environmentand attention to detail is crucial. Such focus createdour patented RR321 bit range with a new air bearingdesign. Changes to key internal features, combinedwith the closest tolerances we have ever put into an airbearing has resulted in performance increases from 15to 30 % over the old RR320 design.The extra protection of the RR440’s patented radialshaped “dual seal” technology delivers extended bearinghours and greater reliability than conventional o-ringseals. The bearing’s Kevlar coated excluder seal protectsthe primary seal from cuttings and debris, making thesystem virtually bulletproof. Plus the Phinodal bearingsleeves dramatically increase bit load and rotation speedcapacities, increasing operational penetration rates andbit life in the most challenging of drilling environments.6Sandvik Mining ROTARY DRILLING BITS AND DRILL STRING TOOLSRR440 bearings have 50 % greater load capacity androutinely achieve over 200 % the bearing life of airbearings.MORE THAN JUST BITSWe pride ourselves on being your total solutionsprovider and preferred partner of choice.

BENEFITS BY APPLICATIONINTERIOR ROW INSERTSInterior row inserts are critical for high bit life and sustained penetrations rates. We select the best inserts for your applicationspecific products.RR221RR321RR440 The unique geometry of the vector shaped interior row inserts attack the rock at the angleof cone rotation to maximize insert penetration in soft and medium-soft formations Sculptured inserts increase the strength by increasing cross-sectional area and byeliminating sharp edges that cause stress risers which can lead to insert breakage. Idealfor soft and medium-soft formations. Chisel TCI (tungsten carbide insert) provides durability and faster cutting action for softand medium-soft formations.Tough conical top inserts in hard rock formations and abrasive rock conditions have ageometrical shape that optimizes both strength and wear resistance.GAGE ROW INSERTSWe offer a range of gage row insert shapes suited to all drillingapplications. Insert selection is optimized for all bits in ourproduct range.RR221RR321RR440The chisel gage insert performs well in soft homogenous drilling conditions. Radial Bow chisel is a good choice in soft to medium-soft formations. The crest geometry of QX gage inserts present a large cross-sectional area to the rock,creating large bottom-hole craters at the bit gage maximzing life and penetration rates.The SWIC shape coupled with proprietary TCI grades increases gage contact in mediumhard abrasive drilling conditions. Ollon, double conical and relief gage SWIC are shapes for medium-hard to hardformations. Conical inserts offer both strength and wear resistance in hard, abrasive rock. PATENTED TRUCUT GAGE CUTTING TECHNOLOGYTrucut gage cutting technology uses a combination of SRTsemi-round top inserts on the gage, and patented off gageinserts. These inserts cut the wall more efficiently, minimizingbreakage and extending bit life and penetration rates.RR221Trucut gage cutting technology10 Sandvik Mining ROTARY DRILLING BITS AND DRILL STRING TOOLSRR321RR440
