Q19-115-T51 Ball-Tooth Drill Bit with Center Depression for Medium-Hard Rock and T51 Compatibility
The Q19-115-T51 center-depressed ball-tooth drill bit is a high-efficiency rock drilling tool engineered by Yanggu Henglong Engineering Machinery Co., Ltd. Featuring an innovative central depression structure with premium ball teeth and wear-resistant materials, this drill bit delivers exceptional balance between drilling accuracy, efficiency, and durability for various engineering applications in medium-hard rock formations.
Key Design Feature: The unique concave center design distinguishes this drill bit from conventional flat-center models, providing superior guidance and correction capabilities during operation.
Performance Advantages
Enhanced Drilling Accuracy: The concave structure maintains straight drilling paths in loose or poorly consolidated rock formations, significantly reducing borehole deviation
Superior Stability: Excellent guidance capabilities ensure consistent performance and precision drilling
Optimal Rock Compatibility: Specifically designed for medium-hard, low-abrasive, and relatively intact rock formations
Broad Equipment Compatibility: Compatible with common rock drilling rod interfaces including T38, T45, T51, and most hydraulic rock drilling rigs
Applications
This drill bit is ideal for demanding applications requiring precise straight-line drilling, including:
Mining operations
Tunnel excavation projects
Slope support and stabilization
Construction projects requiring high-precision boreholes
When used in conjunction with threaded ball-tooth drill bits, it significantly improves both drilling efficiency and final borehole quality.
