Product Overview
The Henglong 5-tooth, 59mm diameter R32 threaded ball tooth drill bit is a down-the-hole hammer drill bit engineered for demanding applications in mining, tunneling, and construction. Featuring R32 standard wave thread for reliable torque transmission, this drill bit delivers exceptional performance in medium-sized drilling operations.
Key Features & Benefits
Five spherical carbide teeth optimize impact force and penetration power for efficient rock breaking
Higher pressure distribution on hard rocks due to fewer teeth configuration
Heat-treated alloy steel shank provides superior fatigue resistance
Low-temperature carbide brazing creates strong connections, reducing button loss risk in high-stress applications
Reduced replacement costs through optimized tooth configuration
Primary Applications
Mining development, tunnel excavation, slope support, foundation engineering, water well drilling, bolt holes, blasting holes, and small-scale exploration operations.
