Tapered Rock Drilling Bit Tapered Button Bit For Small-Diameter Drilling Compatible With Y24 YT28 Q7 Rock Drills Button Chisel Cross Bit Series

Henglong tapered rock drilling bits are engineered for small-diameter drilling and are fully compatible with Y24, YT28, and Q7 light-duty hydraulic rock drills. Designed for quarrying, mining, and tunneling applications, they deliver exceptional wear resistance and fracture toughness.

The Henglong tapered bit series comprises three core types: tapered button bits, tapered chisel bits, and tapered cross bits.

Manufactured from imported steel and equipped with premium carbide inserts — including grades such as YK05, KD10H, and ZCC — these bits are widely used in stone quarrying, underground mining, and tunneling. They deliver reliable drilling performance thanks to their outstanding wear resistance and superior fracture toughness.

Featuring optimized geometry, high-quality steel bodies, and top-tier carbide inserts (YK05 / KD10H / ZCC), our tapered bits offer exceptional structural strength and faster drilling speeds, helping to boost your on-site operational efficiency.

While maintaining excellent hole straightness, the bits ensure smooth cuttings evacuation, delivering stable and consistent drilling performance across a wide range of rock conditions.
