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.
