Brief Introductions of Impregnated Diamond Bits

The impregnated diamond bits are cutting tools. They contain diamond segments bonded to a base material. They are widely applied in cutting non-ferrous materials. The selected grades of synthetic diamond of high quality are distributed in the depth of impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond. This diamond tool is widely applied in the mineral exploration industry.

Features of Impregnated Diamond Bits: 

1. This diamond tool features with fast penetration rate, because the matrix of our impregnated diamond bits is specially designed (it is designed to expose new diamonds to the bits' cutting face as wear occurs).

2. Can help reduce the cost for diamond drilling: our impregnated diamond bits are manufactured to give optimum penetration rates and service life.

3. The hardness and abrasiveness of the formation to be drilled largely determined the optimum diamond size, concentration and matrix type, etc.

Sizes: BQ NQ HQ PQ NQ3 HQ3 PQ3 PCD Coring Bits / PDC Core Bit

Sizes of PDC Cutters: 1304, 1308, as required. PCD/PDC cutters are available in several sizes and grades

PCD/PDC diamond core drill bits are cost effective for drilling in soft to medium sedimentary formations which are homogeneous and competent.
Packing: suitable for export shipping



Polycrystalline Diamond bits that use larger cylindrical shaped cutters that consist of a layer of micron-sized synthetic diamond particles that are mounted on a tungsten carbide substracte.

PDC / PCD Bits are recommended for use when drilling relatively sofet, abrasive, unconsolidated sedimentary formations that are not effectively drilled by surface-set diamond bits. The formation types may range from very soft clay, gypsum or talc to harder types of sandstones. The difference between the various types of PDC / PCD bits is in the degree of cutter exposure and the density (or number) of cutters mounted on the face of the bit.
