Detailed Product Description
High Performance ISO9001 Medium Air Pressure BR2 76mm Tungsten Carbide Drill
Designed for mining, blasting, and water well drilling applications, this industrial rock tool delivers exceptional performance in demanding conditions.
Product Overview
In DTH (Down-the-Hole) drilling, the rock drilling bit serves as a direct extension of the shank, receiving direct impacts from the rock drill piston. Because the piston makes direct contact with the drill bit, minimal energy is lost, resulting in a nearly constant penetration rate regardless of hole length.
Compatibility & Customization
DTH bits are matched with specific hammers based on drilling hole diameter and spline configuration. Customization options include:
  • Tungsten carbide insert profile (spherical, ballistic)
  • Face profile (flat, concave, convex)
  • Flushing hole design
Operating Principle
DTH drilling uses a percussion system where compressed air drives a piston inside the hammer body in an up-and-down motion. This action delivers intense percussive energy to the bit, crushing the rock for efficient drilling.
Key Advantages & Applications
The DTH hammer drilling method offers high performance, particularly in hard rock formations, and helps shorten project schedules. Ideal for:
  • Foundation work
  • Landslide prevention projects
  • Quarrying services
  • Marine civil works
