EASTAR
Torsional impactor is a special drilling speed up tool independently developed by Wuhan Eastar Tools Co., Ltd., which not only has the characteristics and advantages of torsion impact of traditional torsional impact tool, but also pioneers the integration of axial impact function.
Working Mechanism
Application
Increase the drilling efficiency.
Protect drill bit and downhole BHA components.
Advantages
Extended drill bit life (straight and horizontal sections).
Increased overall Rate of Penetration (straight and horizontal sections)
Improved WOB transmission (horizontal section)
Improved tool face stability (horizontal segment)
