Impregnated diamond core bit

Impregnated core bits can drill a broad range of geological formations from the softest to the hardest rock. They are manufactured with very small, high quality synthetic diamonds mixed evenly through a metal matrix. During drilling the matrix wears away evenly resulting in continuous exposure of new sharp diamond points. This gives an efficient and stable cutting action throughout the life of the bit. All bits have extra T.C. and diamond gauge protection. The optimum diamond size, concentration and matrix composition is dependant on the hardness and abrasiveness of the formation to be drilled.

MATRIX TYPE Z2. (Brown)
Very hard matrix. Abrasive resistant. Requires high torque and thrust.

MATRIX TYPE Z4. (Blue)
Hard Matrix. Good performing matrix giving increased penetration rates in abrasive and medium fractured conditions.

MATRIX TYPE Z6 - Z7. (Green)
Medium to soft matrix. General purpose matrix. Free cutting giving good penetration rate in low abrasive medium to fine grained conditions.

MATRIX TYPE Z8 - Z10. (Red)
Soft matrix. Free cutting giving good penetration in very hard fine grained conditions which tend to polish matrix.
