Product name: T51 Thread 4270mm Length Diamond MM Extension Rod For Horizontal Drilling Rig
Product category: Drilling rod
Threaded Connection: T51
Length: 4270mm
KINGDRILLING thread drill rods are produced from high-intensity alloy steel. All trails and threads are created using high-precision CNC machines. The thread is formed by induction hardening, followed by rapid heating and cooling. Precision temperature-controlled heat treatment equipment extends the drill rod's service life and enhances its mechanical qualities.
Holistic carburization raises the carbon content of the drill rod's outer layer while also hardening the exterior steel body. The solid thread fits perfectly with the inner wall of the drill bits, allowing for high precision and efficiency in complex rock and terrain rough drilling tasks such as roadway tunneling, underground mineral, and open pit drilling.

FAQ:
1. How are drill pipes connected?
The full-hole style connection connects inside and outside thickened drill pipes, resulting in a drill pipe joint with an inner diameter equal to the thickened end diameter, both of which are smaller than the inner diameter of the pipe.
2. Superior durability of our products:
Our drill pipes are manufactured from high-quality materials, ensuring excellent durability and longevity. Each pipe has a forged thickening within its one-piece construction. Thick wall thickness and one-piece design create industry-leading strength and long service life. Each threaded connection is precision cut to our strict quality standards.
3. Optimal performance:
Whether you're working in rocky terrains or abrasive soil conditions, our pipes are built to withstand the harshest environments, minimizing downtime and enhancing the overall lifespan of your equipment. Achieve optimal drilling performance with our precision-engineered drill pipes. Designed for minimal friction and efficient energy transfer, our pipes facilitate smoother drilling operations, allowing you to complete projects faster and with greater accuracy.
