numerous benefits of working with impregnated diamond coring bits

The impregnated diamond core bits have emerged as some of the most highly beneficial and most popularly used in the mining industry for a good reason. The impregnated core bits provide quite a lot more benefits when compared to other different types of cutting media. Some of the advantages the impregnated core bits provide include:
i. Wide-ranging applications.
ii. The simple crown geometry makes the bits less likely to suffer in-hole damage than other bits made using other cutting media. For this reason, they have proven to be more tolerant particularly in situations where drillers are experiencing banded or changing geological formations.
iii. The multi-layered arrangement of the cutters delivers better and extended bit life when compared to other types of bits. They are perfectly suited for drilling consolidated, hard and non-abrasive formations.

The construction of this particularly bit incorporates a sintered and powdered crown fused together to a shank or steel body. The powdered crown comprises of 2 layers namely: the matrix which cuts rock while the backing layer connects joins the matrix together with the shank and supports the gauge diameter hard materials.

The impregnated diamond core bit cutting media is made using natural diamond. This material offers a clear advantage when compared to the surface set diamond core bits. It is more beneficial simply because it boasts of controlled, measurable physical attributes particularly in situations where crystal geometry and crystal friability are concerned.

The matrix of the crown offers uniform distribution of the diamond crystals embedded in the powdered metallic bond. Size of the grits as well as the concentration level of the artificial diamond crystals and relative hardness of metal bonds in which the materials are suspended is attributable to the type of matrix distribution.

Reaying Global Co.,Limited produces a wide variety of impregnated matrices with metal layer bonds ranging from hard, ductile, abrasion-resistant, and soft types. Generally, a hard and abrasion resistant matrix is popularly used for drilling an abrasive, soft, but unconsolidated formation. A soft and ductile matrix on the other hand is perfectly suited for drilling formations that are extremely hard, non-abrasive and consolidated. The main objective is to properly match matrix hardness with the right formation hardness as this enables a controlled erosion rate of the metal bond under normal drilling procedures. The controlled erosion continually exposes new and fresh layers of synthetic diamonds that are quite sharp. This will go on until the matrix of the crown is completely consumed.

The matrix, unlike the backing layer has no diamond distributed in the entire volume. Its backing layer comprises of a powdered-metallic metal bond. The bond type of the material delivers superb wear resistance capabilities. The exposed inner and outer surfaces of the gauge diameter of the layer are set using a good combination of naturally mined kicker grade diamond together with tungsten-carbide pads. The materials aforementioned essentially maintain the gauge diameter for the entire lifetime of the core bit. The optional setting is additionally made available where naturally mined kicker grade diamonds are replaced with synthetic varieties. It is best suited for drilling works where the possibility of contamination by natural diamonds is not acceptable.
