Product Overview
The 127mm GT60 Retrac Button Bit is a top hammer rock drilling tool engineered for GT60 thread compatibility. Featuring a 127mm diameter with retractable structure and carbide spherical button design, this drill bit delivers exceptional performance in hard rock drilling applications. It provides superior wear resistance, efficient slag removal, and reliable operation in demanding conditions including mining operations, infrastructure blasting holes, and tunnel excavation projects.
Key Advantages
High-Efficiency Drilling & Increased Productivity
Optimized spherical button layout combined with large-diameter slag discharge grooves increases drilling speed by 15-25% compared to standard drill bits. This results in higher single-shift footage, making it ideal for large-scale mining and infrastructure projects.
Superior Wear Resistance & Extended Lifespan
Engineered with high-hardness carbide teeth and premium quality steel body, this bit delivers exceptional impact resistance and wear resistance. It increases operational lifespan by over 30%, reducing drill change frequency and lowering overall operational costs.
Retrac Retraction Structure for Safety & Reliability
The unique retraction design enables easy drill retraction in case of stuck drill situations, preventing drill pipe breakage and significantly reducing downtime and operational risks in downhole and tunnel operations.
Strong Adaptability High Versatility
Standard GT60 thread compatibility ensures seamless integration with mainstream top hammer drills including Atlas Copco and Sandv equipment. Requires no modifications and is ready for immediate use.
Applications
Metal/Non-metal Mines: Open-pit and underground hard rock blasting holes, exploration drilling
Infrastructure Engineering: Highway and railway tunnel excavation, hydropower station and bridge foundation drilling
Quarries: Large-diameter drilling for granite, marble, and other stone quarrying operations
Geological Exploration: Deep - hole hard rock sampling, geological hazard mitigation drilling
