Single Tube Bit

single Tube Bit This series of impregnated core bits is designed to be sustainable and cost effective. Adjust the bit to accommodate slower rotation speeds and heavy duty field stations. They are less sensitive to abuse, rough handling, and abrasive formations. A range of standard matrices and a diamond impregnated height are available for the most common applications. For field investigations and core drilling in shallow formations of less than 150 m (500 ft), this series of impregnated core bits is your best choice. We are Diamond Tools Manufacturer. FEATURES&BENEFITS * Less sensitive to abuse for high sustainability and cost efficiency * Matrices for a wide range of formations, easy bit selection * Standardized design makes the bit range competitive and cost effective   STANDARD SPECIFICATION ITEM DIAMOND BIT REAMING SHELL Swedish MetricT2Series Size Bit-set OD Bit-set ID mm inch mm inch mm inch 36 36.0 1.417 22.0 0.866 36.3 1.429 46 46.0 1.811 32.0 1.260 46.3 1.823 56 56.0 2.205 42.0 1.654 56.3 2.217 66 66.0 2.598 52.0 2.047 66.3 2.610 76 76.0 2.992 62.0 2.441 76.3 3.004 86 86.0 3.386 72.0 2.835 86.3 3.398 101 101.0 3.976 84.0 3.307 101.3 3.988 SwedishT Series TAW 47.6 1.875 23.2 1.31 48.0 1.89 TBW 59.5 2.345 44.9 1.77 59.9 2.36 TNW 75.3 2.965 60.5 2.38 75.7 2.98   APPLICATION Application 1 Soft to medium hard rock with abrasive and fractured to competent formations  Matrix series 1-4 Application 2 Medium hard to hard rock with slightly abrasive and slightly broken to competent formations  Matrix series 5-8 Application 3 Hard to very hard rock with competent formations Matrix series 9-10   MATRIX SERIES Rock Group Formation Description Rock Type 1-4 Soft to medium hardVery abrasive to slightly abrasiveVery fractured to slightly broken Unmetamorphosed or weakly metamorphosed shales,Sandstone and limestone 5 Medium hardAbrasiveModerately fractured to slightlybroken Limestone and dolomite.Weathered granite and gneiss.Serpentinite and metaperidotite. 6 Medium hardModerately abrasiveModerately fractured to slightlybroken Unmetamorphosed or weakly metamorphosed diorite,Gabbro, peridotite and gneiss.Basalt, andesite. 7 Medium hard - hardModerately abrasiveSlightly fractured to competent Metabasalt, amphibolite.Metamorphosed diorite and gabbro.Diabase. 8 HardSlightly abrasiveCompetent Quartz rich skarn.Granite and pegmatite 9 Very hardSlightly abrasiveVery competent Metamorphosed granitic rock and quartz rich gneiss. 10 Extremely hardNon-abrasive, fine grainedVery competent Chert and jasperite.Quartzite.
