Impregnated drill bit Brief Description
*Extremely hard and abrasive formation drilling
Shallow parabolic crown profile, heavy density impregnated segment layout is applicable to extremely hard and abrasive formation of high compressive strength.
*Impregnated segment
Self-sharpening impregnated segments with high density and large size polycrystalline diamond sintered on the martrix body increase the bit ROP and service life. This bit is recommended to be used under high ROP and high WOB.
