GT60 102mm Dome Retrac Drill Bit Thread Button Bit for Mining Quarrying Rock Drilling

GT60 102mm Dome Retrac Drill Bit

The GT60 102mm Dome Retrac Drill Bit is a high-performance threaded retrac button bit engineered for demanding rock drilling applications in mining, quarrying, construction and tunneling. Featuring a 102 mm drilling diameter with a φ14×8 + φ13×6 dome button configuration, this bit delivers a balanced combination of drilling efficiency, wear resistance and hole stability.

The dome-shaped tungsten carbide buttons maintain effective contact with the rock formation and support consistent penetration performance. The retrac design improves drilling stability and facilitates bit retrieval in fractured or difficult ground conditions, making it a reliable choice for hard and abrasive rock formations.
