This Henglong 8-tooth, 7-degree wear-resistant mining drill bit is engineered for demanding hard rock formations in mining and quarrying operations. The precisely machined 8-tooth structure and optimized 7-degree cutting angle deliver powerful rock penetration and exceptional stability, making it ideal for blast hole drilling, exploration drilling, and production drilling applications.
Key Advantages
8-Tooth Cutting Design
The 8-tooth layout evenly distributes drilling force across the drill bit surface, minimizing localized wear and maximizing contact area with the rock surface.
7-Degree Tapered Cutting Angle
The 7-degree angle is specifically optimized for hard rock drilling, providing superior stability that reduces stress on drilling rig components and extends the lifespan of the entire drilling system.
Universal Compatibility
Designed to fit standard drill rods (including hexagonal and round shank configurations) and compatible with most top-tier mining drill rigs on the market.
