The GT60 Threaded Button Bit is a heavy-duty drill bit from the Sandv system, engineered specifically for top hammer drilling applications. Designed for compatibility with large-diameter, high-power top hammer drilling equipment, this robust tool excels in demanding operations including deep hole drilling in mines and tunnel excavation.

• Extended Service Life: High-hardness tungsten steel ball teeth with surface hardening provide superior wear and fatigue resistance, delivering 20%-40% longer lifespan compared to standard T-threaded drill bits
• Optimized Hard Rock Performance: Flat face design ensures effective drilling in hard rock formations
• Enhanced Deep Hole Operation: Retrac skirt design facilitates smooth entry and exit in deep holes while preventing drill bit jamming
• Superior Cutting Removal: Large-diameter central flushing hole enables high-pressure airflow/water flow to quickly remove rock cuttings, reducing borehole blockage and drill bit wear
• Maximum Efficiency: High energy transfer efficiency and improved drilling performance in challenging conditions
