Impregnated diamond casing & casing shoe bits are the most widely used bits in the industry of mineral exploration since they are versatile and can be put into many good uses. It can be used in a myriad of applications and is regarded as the most efficient tool that aids in advancing casing into thick layers. On the other hand, casing shoe bits are used at the tip of casing tubes which serves as a doorway for executing the drill actions on the bedrock.

Diamond casing shoe bits: The inner sides of casing shoe bits are NOT set with diamonds, it flush with the inside diameter of the casing. the corresponding size of core bits and core barrels can get through the inner diameter of the casing shoe bits freely.

Diamond casing bits: The inner sides of casing bits are set with diamonds, the diameter size is smaller than casing shoe bits, so that the core barrels can NOT get through.

Impregnated diamond casing & casing shoe bits use combinations of carefully selected synthetic diamond crystals that arrive in mesh-size. They are evenly distributed and embedded within a powdered metal bond into the core and matrix of the bit. The main composition of impregnated diamond casing shoe bits and rod shoes is a sintered powdered metal crown joined and blended into a steel tool body. This powdered metal crown is made up of two layers: the matrix, which refers to the layer which cuts through the overburden, and the backing layer, built to connect the matrix layer with the steel tool body and which also supports gauge diameter protection on hard materials. The matrix layer contains diamond crystals uniformly across its volume while the backing layer does not have this property. It is composed of the powdered metal material and exhibits water resistant properties. Both the outer exposed surfaces and inside gauge diameter surface of this layer is set with a mix of natural mined diamond and wear pads sourced from tungsten carbide. The gauge setting materials greatly help in maintaining critical diameters for the duration of the casing shoe life.

Diamond bits are used in an abrasive way, drilling at high speed along with a plowing action. It breaks through the cement of rock grains and works in quite rapid rotations to achieve excellent performance. Impregnated diamond casing & casing shoe bits are designed for opening the hole, and for standard drilling down as well as positioning all sizes of standard casing tubes into certain drill holes. While diamond rod shoe bits are very similar to casing shoes bits, it differs in thread connections and are mainly used for wireline drilling rods.

Impregnated diamond casing shoe and rod shoe bits have high penetration rates, ideally used for drilling of soil or relatively soft ground, with much gravel, up to medium hard formation rocks. The optimum diamond size used, its concentration and the matrix components are dependent on the hardness and abrasiveness of the formation that will be drilled. It is essential to get top quality tools not only to yield the best results but keep costs down as well. These impregnated diamond casing shoe bits and rod shoe bits promote efficiency, exhibit long life for long term use, yet can be acquired at reasonable prices.
