Product Description

The Polygonal Kelly Drill Rod is constructed from alloy steel with specially heat-treated ends featuring taper small pitch threads. Its regular polygonal shape matches drill rig spindles, effectively transmitting torque through the drill string to the drill bit. Engineered for durability and performance, these rods offer excellent cost efficiency, superior wear resistance, and extended service life.
