Product Details
Impregnated Diamond Bit , FI Series , API 7-1 , High ROP , High WOB
, Natural Diamond Segment
FI series
Impregnated diamond drill bit
*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.
