Tungsten carbide core bits are designed especially for soil investigation and geotechnical drilling, but also suitable in some applications for mineral exploration. As the tungsten carbide is softer than diamond stones, the formations which these bits are able to handle are limited in the range of soft or some medium rocks.
We supply two types of tungsten carbide core bits, Octagonal lnserts and quadranguiar lnserts, The standard TC Insert type has a crown with a sawtooth profile, where each tooth is a tungsten carbide insert. Inserts may vary in shape: they may be flat plates that extend across the width of the crown, or octagonal shaped prisms arranged alternately on the inside and outside diameter of the crown. The octagonal inserts are more hard wearing because they have a greater number of cutting edges and are less prone to chip or shatter.
Unless otherwise specified, the octagonal inserts is the standard for this type of T.C. core bits, with various sizes according to different bit kerf widths.
We offer a large range of tungsten carbide tipped core bits and casing shoes to suit most common core barrel and casing types to DCDMA, Wireline and Metric Standards. All tungsten carbide is used in our bits is of the highest quality grade, tried and tested over many years to give optimum performance in geotechnical applications.
