7-tooth 40mm diameter extended body spherical button bit for efficient rock drilling
The Henglong 7-tooth, 40mm diameter extended body spherical button bit is a high-performance drilling tool engineered for exceptional efficiency and wear resistance in small to medium-sized rock drilling operations.
Applications
Compatible with pneumatic and hydraulic rock drills, this drill bit is ideal for:
Secondary crushing operations in mining
Tunnel support and construction
Deep hole drilling applications
Extended Body Design Benefits
The extended body design is the key distinguishing feature that sets this drill bit apart from standard spherical button bits, offering significant operational advantages:
Accommodates deeper drilling requirements without frequent extension rod changes
Enhances connection stability with drill rods for reduced vibration
Improves drilling accuracy and hole straightness
Increases overall torsional and impact resistance
Spherical Carbide Ball Tooth Technology
The core cutting component features spherical carbide ball teeth that provide superior performance compared to traditional flat-bladed drill bits:
Automatic centering during rotation for better drilling concentricity
Even wear distribution for extended sharpening cycles
Reduced auxiliary time for bit changes and maintenance
Enhanced drilling efficiency and operational productivity
