Product Overview
The Hanglong 7-tooth tapered ball-end drill bit is engineered for high-precision surface drilling and narrow-space operations in soft to medium-hard rock formations. Combining spherical drill bit design, optimized tooth layout, and compact structure, it is the ideal solution for tunnel profiling, rock carving, slope reinforcement and anchoring, and applications requiring exceptional drilling accuracy.
Key Features & Benefits
  • Seven evenly distributed carbide buttons designed specifically for contour drilling and curved rock surfaces
  • Spherical design ensures full contact with curved surfaces and even distribution of impact force
  • 7-tooth configuration increases drilling speed by 18-22% in sandstone, limestone, and weathered granite compared to 5-tooth designs
  • 11° taper angle provides stable drilling performance and prevents slippage
  • Compatible with most lightweight drill rods and handheld drilling rigs without custom adapters
  • Ultra-compact 50mm height for access to confined spaces
  • YG11C tungsten carbide buttons deliver high hardness and impact toughness
  • Alloy steel body undergoes double heat treatment (quenching + tempering) for enhanced tensile strength and bending resistance
