Bit
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 in both axial and radial directions by
FBS (Force Balance Analysis) software,
resulting in a more aggressive and durable drill.
The helical blade effectively improves the stability of the drill
bit and the ROP.
