Rock drilling bits
Our tapered drill bits can be made into three shapes, tapered cross bits, tapered chisel bits and tapered button bits, which can definitely meet customers’ demands to drill holes with a small diameter. Typically, tapered drill bits are used with small handheld rock drills. But, our top hammer drill bits feature robust structure and excellent quality and thus can also be used with powerful hydraulic drilling rigs.
