BR2 Down The Hole DTH Rock Drill Bit 76mm
High-performance drilling tool designed for quarry, water well, borehole mining, and medium air pressure fast drilling applications.
Product Overview
The BR2 Shank DTH Button Bit is a high-performance drilling tool specifically engineered for down-the-hole (DTH) hammer applications. Its innovative button-shaped carbide insert profile enhances drilling efficiency and extends bit service life, making it a reliable choice for demanding rock drilling operations.
Key Features & Benefits
- High-Quality Alloy Steel Construction - Manufactured from premium alloy steel with exceptional hardness and wear resistance, ensuring consistent penetration across various rock formations
- Button-Shaped Carbide Inserts - Strategically placed button profile increases contact area between bit and rock surface, significantly improving drilling speed and energy transfer efficiency
- Advanced Heat Dissipation Design - Optimized heat dissipation structure effectively removes heat generated during drilling, reducing thermal fatigue and prolonging bit life
- Threaded Connection - Engineered with robust threaded connection to guarantee secure, vibration-resistant fit with drill string, minimizing downtime due to connection failure
Technical Highlights
In DTH drilling, the bit functions as a direct extension of the shank, with the piston striking it directly. This direct energy transfer minimizes energy loss, resulting in a nearly constant penetration rate regardless of hole depth.
Compatibility: The BR2 bit is paired with corresponding DTH hammers based on hole diameter and spline configuration. Customization options include tungsten carbide insert profiles (spherical, ballistic, etc.), face profiles (flat, concave, convex, etc.), and flushing hole arrangements.
Application Range: Suitable for medium to large drilling diameters and capable of operating under high-pressure conditions for deep-hole drilling.
Color Options: Available in green, blue, or as per customer requirements.
