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.
