AQ Diamond Core Drill Bit

AQ Impregnated Diamond Core Drill Bits for hard rock The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry,Website:http://www.yikuangdrilling.com, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the ZM contains a uniform distribution of these crystals that are embedded in a powdered metal bond.    Matrix hardnessAbrasiveness of matrixSuitable drilling formationGradeHRCExtra soft10-20LowSuitable for drilling extra-hard, compact and weak-abrasive formationSoft20-30Low, mediumSuitable for drilling extra-hard, compact and weak-abrasive formation, extra-hard and medium-abrasive formationMedium-soft30-35Low, mediumSuitable for drilling hard and weak-abrasive formation, hard and medium-abrasive formationMedium-hard35-40Medium-highSuitable for drilling hard and medium-abrasive formation, medium-hard and medium-abrasive formationHard40-45HighSuitable for drilling hard and strong abrasive formationOutside Set Diameterlnside Set DiameterCore BarrelMaximumMinimumMaximumMinimumSpecificationlnchesmmlnchesmmlnchesmmlnchesmmAQ1.8847.751.8747.51.60727.11.05726.85BQ2.3559.692.3459.441.4381.42836.5236.27NQ2.9775.442.9675.191.8847.751.8747.5HQ3.7795.763.75595.382.50563.632.49563.38PQ4.815122.34.795121.83.3585.093.3484.84T2-1013.981101.123.971100.83.383.823.2983.57T6-1013.981101.123.971100.83.11579.123.10578.87Dimensions  of Core BitsWireline drill bitsAQ, BQ, NQ, NQ2,NQ3,HQ, HQ2,HQ3,PQ,PQ2,PQ3T, TT, T2&TB SeriesT36, TT46, T2-46, TB56, TT56, T2-56, T2-66, T2-76, T2-76 Core line, T2-86, T2-86 Core line, T2-101,T2-101Core lineT6 SeriesT6-76, T6-86, T6-101,T6-116,T6-131,T6-146B Series (ISO3552-1)B36, B46, B56, B66, B76,B86, B101, B116, B131, B146WF Series:HWF, PWF, SWF, UWF, ZWFWT Series:RWT, EWT, AWT, BWT, NWT, HWT (Single Tube/Double Tube)WG Series:EWG, AWG, BWG, NWG, HWG (Single Tube/Double Tube)WM Series:EWM, AWM, BWM, NWMN Guage Core BitsWLN, WLN2, WLN3, NMLC, NWG NX, NWM, NWT, TNWH Gauge Core BitsWLH, WLH-3.830, WLH-3.895,WLH3, WLHTT, HMLC, HWF-long, HWM,HWT
