Product Introduction The Tapered Button Bit is a specialized rock drilling tool that utilizes a tapered connection system between the drill bit and drill rod. Unlike threaded connections, the tapered design employs a conical interference fit — commonly at 6°, 7°, 9°, or 11° standard taper angles — to create a self-tightening mechanical bond. Under the high-frequency impact of a rock drill, the conical contact surface generates substantial radial pressure, forming a self
