For small diameter blasting holes, quarrying, underground tunneling, and rock anchoring projects, the selection of a reliable tapered drill bit directly impacts overall on site production efficiency and cost per meter of drilling. The Henglong 32mm 7 degree tapered drill bit is specifically designed for rock drills paired with H22 tapered drill rods and can handle medium hard to hard abrasive rock formations such as granite, basalt, and quartzite.
This 8 tooth tapered drill bit uses high quality tungsten carbide cutting edges and a high strength 45CrNiMoVA alloy steel matrix, providing stable drilling speeds, excellent tooth retention, and a longer service life even in harsh field environments. It is widely used in stone quarrying, metal mine tunneling, construction blasting, and rock anchoring drilling operations.
Key Product Features
  • Optimized 8 Key Layout Configuration The Q8-32-7 model employs a scientific key layout: balanced force distribution reduces drill bit deviation, ensures borehole straightness, reduces premature chipping of carbide cuttings, and improves rock-breaking efficiency.
  • High Quality Carbide Resistant to cracking even under frequent high frequency impacts; reduces drill bit replacement frequency, thereby shortening downtime in mines and quarries.
  • 45CrNiMoVA High Alloy Steel Drill Body The steel body is forged from 45CrNiMoVA and undergoes rigorous quenching and tempering heat treatment. High tensile strength and impact toughness.
  • 7° Precision Taper Interface Suitable for H22 drill rods with precise fit and optimal power transmission.
  • Optimized Three Hole Flushing Design Two front water holes and one side water hole enable multi-directional flushing, quickly removing rock cuttings from the borehole.
Application Scenarios
  • Blasting hole drilling in stone quarries
  • Underground metal and non metal mine tunneling and production blasting
  • Anchoring hole drilling in road and tunnel construction
  • Short hole impact drilling using pneumatic rock drills and handheld rock drills
  • Medium hardness, fractured, and abrasive rock formations
