7 1/2" Steel Body PDC Bit , IADC S323 , 4 1/2” API REG.PIN , 5 Blades

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.

*Depth-control pad

enhancing the ability to drill through soft and hard interbeded formations and protect PDC cutters.

* Inclined gage

forece-balanced that resulting better stability of the bit.

* Double row cutters
penetration ability and wear-resistance of thebit in medium hard formation can beimproved.
