Ntroduction We manufacture core barrels, which are used frequently in mineral exploration, where the coring may be several hundred to several thousand feet in length. exploration diamond core drilling utilizes an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock. The diamonds used are fine to microfine industrial grade diamonds. They are set within a matrix of varying hardness, from brass to high-grade steel. Matrix hardness, diamond size and dosing can be varied according to the rock which must be cut. Holes within the bit allow water to be delivered to the cutting face. This provides three essential functions: lubrication, cooling, and removal of drill cuttings from the hole. The core samples are recovered and examined by geologists for mineral percentages and stratigraphic contact points. Also we produce premuim impregnated diamond core drill bits,non coring bits,reaming shells,drilling rods,overshots and other diamond drilling tools and accessories for site investigation,mineral exploration and water well drill applications.
