Product Details

Description
Hexagonal hollow mining drill rods are used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. Hexagonal hollow mining drill rods work with taper drill bits and has different length for various applications, our taper drill rods come in a variety of taper angles, generally, the light duty rock drill usually use 7°or smaller taper angle, the heavy duty rock drill mainly use 11°,12°. And the basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs.

Performance
High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance

Application
•Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
