The broad objective of a diamond impregnated drill bit is to produce a bit where the matrix under given conditions, erodes at a rate so that. as the active diamonds become blunt they will be released and a fresh sharp diamond will be exposed to continue cutting. The matrix is a critical factor in impregnated bit manufacture as it must have the capacity to retain the diamonds for as long as they continue to cut and then allow the blunt diamonds to “strip” but resist the drilling forces and not allow the sharp diamonds to be “pulled” prior to becoming blunt. 

Diamond concentration is also critical to an impregnated bits performance as it is believed that the increase in concentration increases “strip rate” and also increases the load required for “self sharpening”. There are two elements of an impregnated bits matrix, one is the matrix is far to hard and will not allow worn diamonds to “strip” and the other where the matrix is to soft and allows premature release of the diamond before they are at the end of their useful life.

Our bits are commonly used throughout the drilling industry to perform goetechnical, gas drainage, gas content coring, material sample coring and mineral exploration
