The material used to make KINGDRILLING thread drill rods is
high-intensity alloy steel. High precision CNC machines form all of
the trails and threads. The thread undergoes rapid heating and
cooling followed by induction hardening. The drill rod's mechanical
qualities are enhanced and its service life is guaranteed by the
precision temperature-controlled heat treatment equipment.
The outer layer of the drill rod and the hardened outer steel body
have higher carbon contents thanks to holistic carburization. The
solid thread may be precisely and efficiently fitted into the inner
wall of drill bits to perform a variety of tasks such as 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 component
of drilling pipes that serves as a coupling element to form the
drill string. The joint attaches to the pipe via welding or a
conical thread.
3. How does the drill pipe work?
Drill pipes are sturdy steel pipes that transfer force to the drill
bit. In many situations, the drill pipe rotates the drill bit,
which cuts through the rock until it reaches the deposits.
Nonmagnetic drill collars are commonly used as the last drill pipes
before the drill bit, especially in 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.
