Diamond Core Bit for Geological Drilling Exploration


Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.

Features of Impregnated diamond bit

  • Stabilizers: Wing-like stabilizer fins, buttons or inserts support and guide the bit body while drilling, preventing wobbling for a straighter borehole.
  • Flush Ports: Small holes around bottom and sides of bit body allow flushing fluids to irrigate bit face and carry cuttings up the annulus.
  • Impregnation Method: Vacuum brazing or high pressure sintering fuses diamonds into metalsubstrate at microscopic level for maximum durability.
