Best Diamond Core Drill Bits for Rotary Drilling with High Quality
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.
