Product Description

8-1/2in 5 Blades PDC Drill Bits Cutting Drill Bit PDC Cutters Rock Bit
Double row knives 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 the DOC (depth) of the drill bit, the tool enters the formation more reasonably.
The helical blade effectively improves the stability and ROP of the drill bit.
