The impregnated diamond bits are manufactured using high quality raw materials for optimum drilling performance.
These impregnated bits present a metallic layer impregnated of diamonds on its cutting face.
These impregnated bits are made by mixing fine diamonds with a metallic powder called matrix.
The mixture is then subjected to heat treatment assuring the metallurgical bond of the matrix on the steel blank.
The matrix is critical in a successful Impregnated Core Bit as this matrix must have the ability to retain the diamonds for just as long as they continue to provide an efficient cutting function, which, when those worn diamonds that have ceased providing this function, will be stripped from the matrix and allow fresh, sharp diamonds to be exposed to continue the cutting operation.






These application fields cover geological exploration, engineering construction, environmental protection, resource extraction and other fields.
The design and selection of casing needs to be based on the requirements of the specific application, including factors such as material, size, durability and corrosion resistance.
