Product Details
12 1/4" FS19053I , Steel Body PDC Bit , Polycrystalline Diamond
Compact Bit
FS series
Steel body PDC drill bit
*Soft to medium hard formation drilling
Medium short parabolic crown profile and medium cutter density
helps to obtain better ROP in soft to medium hard formation with
lower compressive strength and thin hard layers.
*Gauge protection
Gauge cutter improves the gage wear-resistance to prolong the
service life of the bit.
*Unique backrack design
Unique backrack design helps to reduce the bit torque and increase
its aggressiveness.
