Description
Impregnated Diamond Core Bit
Impregnated Diamond Core Bit is made from high-quality synthetic diamond and metal powder which could be used in various types of strata. The best effect is achieved through the flexible design according to the different strata and parameters of drilling equipment.
Surface Set Diamond Core Bit
Surface Set Diamond Bit is produced from a single layer of natural diamond setting on the surface of bit crown with hard matrix, and primarily recommended for drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit. It is also recommended for drilling harder formations, which the available rotary speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.
In most cases, Surface Set Diamond Bits will provide higher rates of penetration than in softer formations due to the greater degree of exposure of the individual diamond crystals.
