How many diamonds are used and the hardness of the matrix are related to the hardness of the rock. Drill matrices are developed to perform ideally within a certain range of the scale so you need to pick a bit suitable to the hardness of the ground to be drilled. Harder ground needs a bit with a higher number.
The drill uses a diamond encrusted drill bit (pictured on the right) to drill through the rock. The drill produces a "core" which is photographed and split longitudinally. Half of the split core is assayed while the other half is permanently stored for future use and re-assaying if necessary.

15/4/2020 · Diamond core bits, also known as diamond drill bit, are the perfect tools to use when you want to drill holes through hard materials. These hard materials include stones, rocks, porcelain, tiles, and even some hardwoods.
25/8/2019 · To improve the drilling efficiency of impregnated diamond drill bit in strong abrasive rock layer, this paper introduces the theory of primary and secondary abrasives into the drill bit design, and explores the drilling efficiency and service life of diamond drill bits with six formulas of primary and secondary abrasives through indoor and field tests.
Diamond-tipped drill bits are what is used to make holes in rocks. The diamond material provides a hardness that metal alone cannot provide. Smaller bits will encounter less resistance during drilling but they are also more prone to breaking than bits with larger diameters.

The medium size rock if often cut with a software drill bit and the harder rock always cut with a smaller diamond. Surface set diamond core bits: Surface set diamond core bits are featured with several layers of natural diamond normally on the active places of the bit crown on a particular predetermined pattern.
HAYDEN uses a number reference guide (Hayden 1-16), corresponding to the matrix hardness for ease of selection.(Hayden 1 being the hardest matrix and Hayden 16 being the softest.) The higher the number, the harder, finer grained, more competent and non-abrasive the rock type the bit is capable of drilling.
HX NX BX Diamond Core Drill Bits. Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock.
1/1/2014 · Aiming to the drilling characteristics of hard rock in deep borehole, a new kind of impregnated diamond bit was redesigned from structure, matrix formula, parameters of diamond and etc. in the paper. According to the design, the new long life impregnated diamond bit was developed, which could significantly improve drilling efficiency and reduce drilling …

Diamond core drilling rigs utilize a diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock. Through the holes in the bits water comes to the cutting face. This provides lubrication, cooling and removal of drill cuttings from the hole.
Diamond core drilling uses a diamond bit, which rotates at the end of drill rod (or pipe) (Figure 16 – 1). The opening at the end of the diamond bit allows a solid column of rock to move up into the drill pipe and be recovered at the surface.
Exploration diamond drilling differs from other geological drilling (such as Reverse Circulation (RC) Drilling) in that a solid core is extracted from depth, for examination on the surface. The key technology of the diamond drill is the actual diamond bit itself. It is composed of industrial diamonds set into a soft metallic matrix. As shown in the figure, the diamonds are scattered …
