Product Overview
The Henglong 38mm 7-Teeth Tapered Button Bit is a high-efficiency drilling tool engineered for medium-hard to hard rock drilling applications. This precision tool delivers stable drilling accuracy, powerful rock-breaking capabilities, and exceptional service life, making it ideal for mining operations, tunnel excavation, and engineering blasting projects.
Taper Angle Options

Common taper angles include 7° and 11°, designed to match different drilling rigs and rock formations:

  • 7° Taper Angle: Focuses on drilling stability and precision
  • 11° Taper Angle: Prioritizes efficient rock breaking and penetration
Advanced Tooth Design
  • 7-Tooth Configuration: Evenly distributed ball-tooth layout for balanced impact force distribution
  • Superior Wear Resistance: Prevents excessive wear on individual teeth compared to 5-tooth and 6-tooth designs
  • 360° Cutting Capability: Spherical carbide inserts eliminate blind spots and maintain rock-breaking efficiency even after blunting
