Product Description

Introduction :
Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic 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.

They are manufactured with very small, high quality synthetic diamonds mixed evenly through a metal matrix. FORSUN core bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to minimum.
