Product Description

Face Discharge Profile Diamond Core Bit / Wire Line Drilling Stone Core Drill Bits

 

Diamond Core Bit

N/WL,STD profile(75.31mm/45.08mm), Suitable for Fractured formation, when need Complete core.

Face discharge profile
 

The impregnated diamond bit is used for cutting holes in medium to ultra hard formations. A variety of variations are available to maximize drill life and penetration

 

The crown is made up of a metal powder and diamond matrix that wears away during the drilling process and exposes new layers of diamonds, renewing the cutting
