Product Overview

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.

Key Features

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
