Product Description
High Performance Trenchless Drilling Equipment Drill Collar
Drill collars are essential components of drill strings that provide critical weight on the drill bit for efficient trenchless drilling operations. Manufactured from solid steel bars with wall thicknesses ranging from 38mm to 53mm, these heavy-duty components deliver superior performance in demanding drilling environments.
Product Overview
Our drill collars are precision-machined from solid steel bars, typically plain carbon steel or premium non-magnetic alloys including nickel-copper compositions. Each unit undergoes rigorous heat treatment processes including quenching and tempering to achieve optimal mechanical properties, followed by precision trepanning, drifting, and threading operations.
