Description

Polygonal Kelly Drill Rod Pipe with Taper Small Pitch Thread for Mining And Well Drilling Rig Machine

Brief Introduction

The Kelly Drill Rod is made of alloy steel, and the two ends are specially heat-treated to be processed into a taper small pitch thread. The shape is a regular polygon according to the drill rig's spindle, and the torque of the drill rig is passed through the drill string and finally transmitted to the drill bit at the bottom. It has the characteristics of high cost efficiency, good wear resistance and long service life.
