Diamond Core Bit

B/WL-3, Taper Profile(59.56mm/33.53mm), suitable for Fractured formation, when need Complete core.

Impregnated diamond bits are used to cut holes in medium to superhard formations. There are many types available to maximize bit life and penetration depth. The crown is composed of metal powder and diamond matrix, which will wear during drilling and expose new diamond layer, thus renewing the cutting process.

To help customers choose the right bit and reduce their workload, please select your bit according to the following three steps.

{1}Assure diameter of Impregnated bit

{2}(1)Appropriate hardness of matrix(For some special or complicated ground,we will need to customize the diamond bits according to the actual drilling conditions.)

(2)Appropriate profile/water way and height of the crown(Height of the crown:9mm-20mm,standard:14mm,Customized)
