Mining Exploration Wireline Drilling AQ BQ NQ HQ PQ Impregnated Diamond Core Bits Geological Drill Bit
Diamond core bits products include: 1,drill bit: Impregnated diamond diamond drill bit, sufface set diamond drill bit, electroplated diamond drill bit, tc drill bit, PCD drill bit, thin wall drill bit; Hole: alloy reamer, polycrystalline reamer, electroplated reamer,surface set natural diamond reamer;
The impreqnated diamond bits have the widest range of application. They are the most commonly useful bits from medium to super hard formations in the mineral exploration industry, the Hardness and abrasive of the rock formation are the key factors to determine the diamond specifications,concentration and matrix hatdnesS. Toothed bits can get higher drilling efficiency when it is drilling at dense or abrasive stratum with lower drilling speed and pressure.It was especially effective at coal formation, using toothed bits can get better water flowing and drling footage effect. Nowadays, Impregnated diamond bits have been widely used in wire-line drilling series.
