1). how to choose the suitable impregnated type core bits for drilling different hardness rocks?

Answer: we have ten grades of matrix, which is for drilling rocks from soft, medium to hard, superhard. Soft rocks including clay, sandstone, gypsum, talc, tuff, shale, serpentinite, calcite; Medium rocks including siltstone, limestone, marble, andesite, dolomite, reinforce concrete, porphyry; Hard rocks including basalt, pegmatite, gabbro, schist, norite, syenite, peridotite; Very hard rocks including amphibolite, diorite, gneiss, granite, rhyolite, quartzite, ironstone, taconite, jasperite, quartz, chert.

2). how to choose the suitable surface set type, tungsten carbide type, electroplated diamond type core bits and reaming shells for drilling different hardness rocks?

Answer: Soft rocks including clay, chalk, gypsum; Soft~Medium rocks including sand, shale, salt, hard shale, ice; Medium hard non abrasive rocks including sandy shale, shale, claystone, sandy limestone; Medium hard abrasive rocks including siltstone, alluvial dep, calcitic hard, shale; hard abrasive rocks including hard limestone, schist, serpentine; hard non abrasive rocks including hard schist, hard siliceous, dolomite, marble, syeite, diabase, pegmatite, hematite, magnetite; very hard rocks including gneiss, granite, basalt, diorite, gabbro, rhyolite, amphibolite; very abrasive rocks including conglomerate, taconite, abrasive quarzite, abrasive sand stone.
