Our friction welded drill rods are designed for optimal performance in well digging machines and various drilling applications. These high-quality components are engineered for durability and efficiency in demanding environments.

Integral drill rods are ideal for small hole drilling applications. Each rod consists of hex-shaped rods with integrated cemented carbide chisel-shaped bit heads. Manufactured with premium Chinese steels and carbides, we offer various lengths and head diameters to suit different requirements.

These integral drill rods are specifically designed for use with handheld drill machines in underground mining and small hole drilling applications. Compatible with air leg rock drills and handheld rock drills, they significantly reduce impact energy expenditure while improving drilling speed and efficiency.

The rods are suitable for drilling bore holes with diameters ranging from 30mm to 41mm. The quality of both the steel material and tungsten carbide components is critical for achieving optimal drilling performance.

• Steel Pipe Thickening: The outer surface is bent inward to thicken the pipe wall, enhancing strength and wear resistance.
• Thread Processing: Threads are precision-cut on thickened pipes and copper-coated to increase strength, improving fatigue resistance and connection durability.
• Welding Treatment: Pipe body joints are welded, followed by heat treatment to eliminate residual welding stress.
• Quality Inspection: Rigorous testing including hardness, pressure, and non-destructive examinations ensure all products meet strict quality standards before painting and packaging.
