8.5in 5 Blades Diamond PDC Bit Oil Well Drilling Machine Stone
Drill Bit
Provides multiple advantages in interbed lithology.
Enhanced drill bit stability with BHA shock and vibration
mitigation.
Increases cleaning and decreases balling.
Superior PDC tool technology for perfect impact strength and wear
resistance.
Double row cutters extend aggression and durability.
FEA software for tool distribution and layout makes drilling more
efficient and reduces NPT.
The tool angle is optimized axially and radially by FBS (Force
Balance Analysis) software, resulting in a more
aggressive and durable drill.
Through a series of empirical calculations and optimization of DOC
(depth) of the drill bit, the tool can enter the
formation more reasonably.
The helical blade effectively improves the stability and ROP of the
drill bit.
