Product Description

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 formaiton. Through the flexible design to achive the drilling.

Surface Set Diamond Core Bit

Surface Set Dimond Bit is produced from a sinlge layer of natural diamond setting on the surface of bit crown with hard matrix and primary recommended for drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit. It is alsorecommended for drilling harder formations which the rotary speed and bit load 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 crystal. 

Tungsten Carbide Core Bit 

Tungsten Carbide Core Bits are designed especially for soil investigation and geotechnical drilling, but also suitable in some applications for mineral exploration. As the tungsten carbide is softer than diamond stones, the formations are limited in the range of soft or some medium rocks, like the overburden drilling, cleaning of drill holes, such as for the removal of steel fragments in hole 

PDC Core Bit 

PDC Core Bit has a long working life, every fast penetration and high percentage core recovery in soft to hard rock formations. PDC bit mostly be used for drilling with air, mud or foam lushing
