Description
Horseshoe Drill Bit: Reduced Stress Concentration and Improved Chip Removal
The horseshoe-shaped drill bit is a specialized impact drill bit featuring a unique U-shaped/arc-shaped cutting profile that resembles a horseshoe. Designed for use with rock drills and tapered/threaded drill rods, this innovative design balances drilling efficiency, hole quality, and wear resistance. It is particularly effective in fractured, jointed, or medium-hard rock formations where traditional chisel-shaped drill bits are prone to chipping or jamming.
Advanced Cutting Design
The cutting head features a horseshoe-shaped cutting edge constructed from durable cemented carbide. This curved design significantly reduces stress concentration, enhances chip removal efficiency, and prevents cutting edge chipping in fractured rock conditions. Unlike conventional rock drill bits with straight cutting edges, the horseshoe-shaped configuration provides superior performance on uneven rock surfaces and fractured formations.
Technical Specifications
The cutting edge radius can be customized according to diameter requirements, typically set at 1/2 of the drill bit diameter (standard U-type configuration).
Rock Hardness Compatibility: Medium-hard to hard rock (f=8-14)
Optimal Applications: Fractured, jointed, and uneven rock formations
Primary Application Scenarios
  • Mining and Underground Engineering: Excavation of underground mine tunnels, small blasting holes, anchor bolt holes, and grouting holes - particularly effective for fractured ore bodies and surrounding rock
  • Tunnel Construction: Anchor bolt hole excavation for traffic tunnels, subway tunnels, and secondary lining applications, plus advanced geological exploration holes in jointed rock formations
  • Stone Processing and Quarrying: Extraction and block splitting of marble, granite, and limestone while preventing damage to stone edges
  • Geotechnical Engineering: Slope reinforcement, foundation pit support, anchor cable drilling, and geological exploration in fractured rock formations
