Construction of Impregnated Diamond Type

Impregnated Bits

The basic construction of Impregnated bits 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 rock and the “backing” layer which connects the matrix layer to the steel tool body and serves to support the gauge diameter protection hard materials.

The cutting media that is used in impregnated bits is NATURAL diamond. The material has a distinct advantage over the natural mined industrial diamond that is used in surface-set bits in that it is an engineered material that has measurable, controlled physical properties, particularly in the areas of crystal friability and crystal geometry.
