Coal mine drill bits are drilling tools used for bolted connections. The 45G Coal Mining Drill Bit is a commonly used drilling tool in coal mining operations. These double-wing integral structure bits feature two cutting edges to improve drilling efficiency and stability.
Available with various connection methods including snap-fit for quick connection/disconnection with drill pipes, and threaded connections with common specifications (R22, R32, T45). The cutting part uses cemented carbide while the trouser body is constructed from high-strength tool steel with rigorous heat treatment to ensure strength and prevent breakage.
Primarily used for drilling anchor support holes in soft to medium-hard rock, these bits are particularly suitable for anchor bolt support operations in coal mine roadways, including roof anchor bolt hole drilling.
