Product Overview
Polygonal Kelly Drill Rod Pipe with Taper Small Pitch Thread for Mining and Well Drilling Rig Machine
The Kelly Drill Rod is manufactured from alloy steel, with both ends specially heat-treated and processed into taper small pitch threads. Designed with a regular polygon shape to match the drill rig's spindle, this pipe efficiently transmits torque from the drill rig through the drill string to the drill bit at the bottom. It offers excellent cost efficiency, superior wear resistance, and extended service life.
