Regular ( Style W’) Waterway 117.65mm HWT HW Diamond Impregnated Casing Shoe
This group of products is used on the leading edge of a casing tube string to advance it through the overburden layer and into the bedrock by means of rotational drilling. Depending on the range of application, the cutting media on the core bit may take the form of synthetic diamond, tungsten-carbide particles or tungsten-carbide elements
The diamond impregnated casing shoe is the most commonly used as it has the widest range of application and is generally the most efficient tool for advancing casing through overburden layers.
In addition to casing shoes, Sinocoredrill also manufactures diamond impregnated rod shoes. In terms of design, rod shoes are very similar to casing shoes and differ only in their thread connections. Rod shoes are used where wireline drill rods are used as casing tubes.
The basic construction of these casing shoes and rod shoes features a sintered powdered metal crown that is fused to a steel tool body or shank. The powdered metal crown is composed of two layers: the “matrix” layer which cuts the overburden and the “backing” layer which connects the matrix layer to the steel tool body and serves to support the gauge diameter protection hard materials.
