Product Description -PRODUCT BRIEF-The drill body of the product is 42crmo. 42CrMo steel belongs to ultra-high-strength steel, with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and resistance to multiple impacts after quenching and tempering. Ability, low temperature impact toughness is good. The steel is suitable for the manufacture of large and medium-sized plastic molds that require certain strength and toughness. Alloy grade: YK05.DTH hammer is a component of subsurface drilling RIGS. The working device belonging to the subsurface drilling RIGS DTH hammer is divided into low wind pressure DTH hammer, medium wind pressure DTH hammer, and high wind pressure DTH hammer.Scope of application: Suitable for limestone, carbonate, sandstone, granite, green rock, clay rock, chalk rock, etc. Suitable for rock, quarry, geothermal, water well, pile hole, etc.Product DescriptionDTH Drill bit features:Fast drilling and retrieval!High efficiency, low labor intensity of workers!DTH Drill bit usage: Widely used in earth and stone engineering mining Wells drilling construction projects drilling Wells edge pillar support.DTH Drill bit model:Medium/Low wind pressure DTH Drill bit:80 90 100 110 120 130 140 150 180 185 200 220High wind pressure DTH Drill bit:115 127 138 152 165 178 195 203 216 240 254 304DTH Drill bit type:Medium/Low wind pressure DTH Drill bit,High wind pressure DTH Drill bitDTH hammer model:Medium/low wind pressure DTH hammer:CIR65 CIR70 CIR90 CIR110 CIR130 CIR150 CIR170 CIR200 High wind pressure DTH hammer:DHD340 DHD350 DHD360 DHD380 N125 SD12DTH HAMMER application scope:Widely used in metallurgical, coal, chemical, building materials are not busy mines and water conservancy, hydropower, highway and railway defense construction projects, etc. Suitable for dry wind water mixing and shotgun-hole water gushing wet operation, reliable performance, is the ideal drilling hole and rock drilling equipment.DTH HAMMER application scope:When the impact stroke begins, piston and disc are in the upper position, air pressure passes through radial holes in the bonnet and seat into the upper chamber of the cylinder, push the piston down at high speed to impact the drill bit. When the piston goes to the spline keyway of the bushing is closed, Pressure in the lower cavity begins to rise, the center hole at the top of the piston leaves the valve rod, ventilate the upper chamber, drop in pressure end of work trip. When the piston hits the end of the bit, because of the upper and lower pressure difference, the valve disc reverses and the piston returns to the stroke repeatedly. - DTH hammer bits benefits -Drill DiameterThe connection specificationAlloy (star)StomatesWeight(KG)Notes5029×4511With type 50 hammer6537×4611.4With type 60 hammer7644×4822.2With type 70 hammer8050×6823.2With type 80 hammer9054×610/112/33.9With type 90 hammer10054×610/112/34.1With type 90 hammer11054×6/60×4/65×6132/36.0With type 90/100B/110 hammer12054×6/60×4/65×612/132/36.2With type 90/100B/110 hammer13054×6/60×4/65×61537.2With type 90/100B/110 hammer14060×4/65×61537.9With type 100B/110 hammer14560×4/65×61638.2With type 100B/110 hammer15060×4/65×6/90×616/2038.6-19.8With type 100B/110/150 hammer16065×6/90×620/21319.3With type 110/150 hammer17065×6/90×620319.8With type 110/150 hammer17565×6/90×620/21320With type 110/150 hammer18065×6/90×620321.6With type 110/150 hammer20090×620324With type 150 hammer10564×81328With type 340 hammer11564×81328.5With type 340 hammer14082×814212With type 350 hammer-DTH hammer bits benefits -The ball tooth:It is mainly used for DTH drill bit edge teeth, suitable for very hard rocks with strong abrasivity.Parabolic tooth:It is mainly used in DTH drill bit side and middle teeth, suitable for rocks with medium and hard wear.Warhead tooth:It is mainly used in DTH drill bit middle teeth, suitable for abrasive medium hardness medium rocks. The soft rock can also be made edge teeth.Sharp tooth:Mainly used in DTH drill bit middle teeth, suitable for soft rocks with high drilling speed and low tooth fracture rate.-DTH hammer bits benefits -1.Due to the special internal structure of the DTH hammer designed according to the latest drilling theory, it can provide the maximum energy for the bit, with high drilling speed and low gas consumption.2.Due to the use of high-quality alloy steel materials and advanced processing technology, the performance of DTH hammer is stable and its service life is long.3.Because of the simple and reliable internal structure, the hammer is easy to disassemble, low failure rate and easy to maintain.4.Due to the multi thread connection of chuck and hydraulic cylinder, it is easy to separate the drill from the hammer.5.Interchangeable with DTH bit and drill pipe.Our company provides low pressure DTH Drill bits and off center DTH Drill bits.We can make different specifications and different forms of alloy ball bit according to different needs of users.It is widely used in mining, tunnel excavation, underground plant excavation and other construction sites.It is an ideal substitute for the same type of ball bit abroad, with stable quality and high cost performance.Strata Grading InstructionsGrade 1 loose soil: secondary loess, secondary laterite, soft sandy soil without gravel and breccia, diatomaceous earthGrade 2 loose rocks: loess, laterite, peat, clay, sand, kaolinGrade 3 soft rocks: strongly weathered shale, slate, dry pasture and schist, slightly cemented sandGrade 4 slightly softer rocks: shale, sandy shale, oil shale, carbonaceous shale, calcareous shale, sand-shale interbedded, argillaceous limestoneGrade 5 slightly harder rock: gravel and gravel layers, collapsible layers, argillaceous slate, sericite chlorite slate, schist, limestoneGrade 6-7 medium hard rock: chlorite, mica, slate, dry pasture, schist, silicified limestone, calciteGrade 8-9 hard rock: silicified mica, gneiss, basalt, diabase, pyroxenite, quartz Anshan porphyryGrade 10-11 hard rock: granite, granodiorite, gneiss, rhyolite, quartziteLevel 12 Hardest Rocks: Quartzite, Jasperite, Cape Shale, Corundum, Quartz, Flint, Jasper Rock grouping and recommended use of the bit tableGrade nameRepresentsDrilling speedSuggested drill bit1Loose soilredeposited loess,lateritite,Soft sandy soil free of gravel and breccia,diatomite15/HPineapple bit,slice,plain film,Scraper coreless bit2Loose soilloess,red clay,cumulosol,Sand soil,Kaolin class8/HPineapple bit,denticle,slice,Triangle,Bread3Soft rockStrongly weathered shale,Slate,schist,Slightly cemented sand layer6/HScraper coreless bit,Concave three wings,slice,Breadslice4A little soft rockSlate,arenaceous shale,carbonaceous shale,argillaceous marl,calcareous shale5/Hscraper,Recessed coreless bit,slice,Bread,Breadslice,Triangle,Electroplated diamond5A little hard rockRubble and gravel layer collapse layer,Slate,limestone,Marble,schist3/HConcave three wings,Bread,A helmet piece,Electroplated diamond6-7Medium hardnessSlate,schist,Silicified limestone,Calcite2/HBread,A helmet piece,Electroplated diamond,Hot pressed diamond,Innovative no.7 fast bit6-7Medium hardnessSlate,schist,Silicified limestone,Calcite2/HBread,A helmet piece,Electroplated diamond,Hot pressed diamond,Innovative no.7 fast bit8-9Hard layerBasalt,Quartz anshan porphyry,Fai green rock1.2/HA helmet piece,Low-alcohol electroplating,Low thermal,Innovative no.7 fast bit10-11Super Hard rock Granite,granodiorite,gneiss,rhyolite,aposandstone0.8/HLow-alcohol electroplating,Low thermal,Innovative no.7 fast bit12Super Hard rockaposandstone,jasperite,hornberg,corundolite0.3/HLow-alcohol electroplating,Low thermal,Innovative no.7 fast bit-APPLICATION RANGE- Apply to:Water Well Drilling/civil engineering and infrastructure/for rock core drilling/geological coring exploration/Soil Testing and sampling /geophysical survey/mineral exploration and other industries. -WHY CHOSE US- pearldrill is a leader in the manufacture and development of PDC bits in China.
