Double row knives extend aggression and durability.
FEA software for tool distribution and layout makes drilling more efficient and reduces NPT.
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.
