Product Description

BR3 90mm DTH Bit - Convex Face Semi-Ballistic Button Rock Drill Bit

The BR3 90mm DTH Bit is a high-performance Down-The-Hole (DTH) rock drill bit designed for efficient drilling in hard and abrasive rock formations. Featuring a 90 mm drilling diameter, convex face design, and semi-ballistic tungsten carbide buttons, this DTH bit provides a balanced combination of rock penetration, impact resistance, and wear performance.

The BR3 90mm bit is configured with 6 × 14 mm, 4 × 12 mm, and 2 × 10 mm semi-ballistic buttons. The optimized button arrangement helps distribute impact energy across the bit face and supports efficient rock breaking during DTH drilling operations.

The convex face design is suitable for applications requiring effective penetration and good flushing performance. The bit is designed for use with compatible BR3-series DTH drilling systems and can be supplied for mining, quarrying, construction, geotechnical drilling, and other hard-rock drilling applications.

For different rock conditions and drilling requirements, button configuration, face design, diameter, and shank specifications can be customized subject to the applicable DTH hammer system.

Applications

  • Mining and mineral exploration
  • Quarrying and dimensional stone
  • Construction and foundation drilling
  • Geotechnical drilling
  • Water well drilling
  • Blasting hole drilling in hard and abrasive rock formations

Features and Advantages

  • 90 mm Drilling Diameter - Designed for drilling applications requiring a nominal 90 mm borehole diameter.
  • Convex Face Design - The convex bit face supports efficient rock penetration and effective cutting removal during DTH drilling.
  • Semi-Ballistic Carbide Buttons - The semi-ballistic button profile provides an effective balance between penetration performance and resistance to impact and wear.
  • Optimized Button Configuration - Uses 6 × 14 mm + 4 × 12 mm + 2 × 10 mm semi-ballistic buttons for a total of 12 carbide buttons, distributing impact energy evenly across the bit face.
  • Designed for Hard Rock Drilling - Suitable for demanding applications involving hard and abrasive rock formations, depending on drilling conditions and operating parameters.
