Product Overview

The integrated high-temperature blast furnace drill bit and drill rod consist of a drill body and drill bits mounted on the carrier. The drill body is designed with a conical structure, and drill bits are arranged on the surface of the cone to enhance drilling performance.

Multiple drill bodies are evenly spaced along the drill rod, and the diameter of each drill body gradually increases from front to rear. The drill rods between adjacent drill bodies can be connected by live pins, ensuring stable operation and convenient assembly.
