Product name: 18" 5485mm Length GT60 Thread Extention Rod For Mineral Exploration Drilling

Product category: Drilling rod

Threaded Connection: R22, R25, R32, R38, T38, T45, T51

Length: 5485mm

Alloy steel with high-intensity is used to make KINGDRILLING thread drill rods. High precision CNC machines form all of the trails and threads. The thread undergoes rapid heating and cooling, followed by induction hardening. Precision temperature-controlled heat treatment equipment extends the drill rod's service life and enhances its mechanical characteristics.

The carbon content of the drill rod's outer layer and the steel body's hardened outer layer is increased through holistic carburization. Solid thread drill bits fit exactly into the inner walls of the drill bits, enabling precise and efficient completion of a variety of tasks including open pit drilling, underground mineral, and roadway tunneling in difficult rock and terrain.

FAQ:

1. What is a drill rod?

A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter.

2. What are pin and box threads?
A box and pin junction, also known as a tool joint, is a type of drilling pipe that serves as a coupling element to form the drill string. The joint is connected to the pipe using welding or a conical thread.

3. How does the drill pipe work?
Drill pipes are strong steel pipes that carry force to the drill bit. In many cases, the drill pipe twists, causing the drill bit to cut into the rock until it reaches the deposits. Nonmagnetic drill collars are frequently used as the final drill pipes before the drill bit, especially when horizontal drilling.

4. How do you harden a hardening drill rod?

HEAT TREATMENT Sections smaller than ¼” heat to 1450°-1475°F and hold until heated through. For larger sections, preheat to 1200°F, the raise to 1450°-1500°F to hardening temperature, hold one-half hour per inch of cross section. Quench in oil at 125°-150°F and TEMPER IMMEDIATELY.
