1. Impregnated Diamond Core Bitsare 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.
2. Surface-Set diamond bits
are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.
Drill soft to hard rock, widely used in all kinds of drillings for prospecting, water and electricity building and construction industry of road, railway, bridge and building taking out core to examine stake, etc.
Different matrix type with better suitable different rock formations.
