Made in China High Power Air Compressor

Product FeaturesUsing pure copper motor, long service life and guaranteed quality. Low energy consumption, simple operation and good disintegration.It is suitable for drilling and pulling back of different holes, and can also be used with down-the-hole drilling rigs for core drilling, chemical industry, mine drainage and soft foundation grouting. product description Introduction to PDC tools: Hunan Fengsu Industry and Trade Co., Ltd. is a leading manufacturer specializing in R&D, design and production of diamond composites. Our TD tools are the most advanced PDC tools available Material: PDC-polycrystalline diamond compact is composed of polycrystalline Diamond layer and tungsten carbide substrate. The polycrystalline diamond layer has extremely high hardness and Wear resistance, while the wear resistance of tungsten carbide substrates will be greatly improved Ductility and capacity of monolithic composites. Diamond thickness increased to 1.8mm -2.3mm Improve impact strength and abrasion resistance Heat resistance increased to 750 degrees Celsius compared to 700 for the previous ZM Long life and stable performance feature: The choice of diamond powder is higher. Using a new type of tungsten carbide, the bond strength characteristics have been improved. The interface claw is changed to a mesh groove, which consists of 20 vertical grooves, and the groove depth is shallow. The internal structure of the sintering tank has been improved to make the pressure and temperature more uniform. New super heat-resistant metal is used to avoid contamination during sintering. The sintering process was modified to improve the bonding strength of diamond-diamond bonds between diamond layers. Increase the diamond content, the thickness of the diamond layer increases to 2.0mm Application: Oil Drilling / Mining / Coal Drilling / Geological Exploration QualityISO 9001:2008 Packing: plastic box Specification of diamond cutters PDC cutters:Dimension CodeDiameter (mm)Height (mm)Polycrystalline table thickness (mm)Polycrystalline chamfer (mm)Carbide chamfer (mm)HSCODE08088.00±0.038.0±0.12.1±0.20.40±0.10.76±0.2582071910100810.00±0.038.0±0.12.1±0.20.40±0.10.76±0.25130513.44±0.035.0±0.11.5±0.20.35 x 45°0.5 x 45°130813.44±0.038.0±0.11.5±0.20.35 x 45°0.5 x 45°131313.44±0.0313.2±0.12.1±0.20.40±0.10.76±0.25160815.88±0.038.0±0.11.5±0.20.35 x 45°0.5 x 45°161315.88±0.0313.2±0.12.1±0.20.40±0.10.76±0.25161615.88±0.0316.3±0.12.1±0.20.40±0.10.76±0.25191619.05±0.0316.3±0.12.1±0.20.40±0.10.76±0.25Remarks:Customized Specifications Upon requestStrata 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, JasperRock grouping and recommended use of the bit tableGradenameRepresentsDrilling 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 rockGranite,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,In
