KINGDRILLING threaded drill rods are made of high-strength alloy steel. All tracks and threads are machined by high-precision CNC machines. The threads are induced by induction hardening, followed by rapid heating and cooling. Precision temperature control heat treatment equipment ensures the service life of the drill rod and improves the mechanical properties of the drill rod.

Overall carburization increases the carbon content of the outer layer of the drill pipe and hardens the outer steel body. The solid thread can perfectly fit the inner wall of the drill rod, completing various tunnel excavation, underground mineral and open-pit drilling tasks in complex rocks and terrains with high precision and efficiency.

FAQ:

1. Is a drill rod what?
An example of a machined bar stock used to make drill bits, taps, dowel pins, shafts, reamers, files, punches, and hammers is called a drill rod. It can be heated to return to its hardness even though it is sufficiently pliable to form. Tool steel that has been ground to a certain tolerance diameter is used to make drill rods.

2. What do box and pin threads mean?
Drilling pipes that function as coupling elements to form the drill string include box and pin joints, sometimes referred to as tool joints. The conical thread or welding is used to link the joint to the pipe.

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.
