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.

Key Features & Advantages

• High Wear Resistance — Tungsten carbide dome buttons provide excellent resistance to wear and impact when drilling hard and abrasive rock.
• Stable Drilling Performance — Optimized button arrangement maintains effective rock contact and stable penetration.
• Retrac Design — Enables easier bit retrieval and improved stability in fractured or variable ground conditions.
• Durable Bit Body — High-strength alloy steel body withstands repeated impact and drilling loads.
• Wide Application Range — Suitable for mining, quarrying, construction, tunneling and rock excavation.
• Customizable Configuration — Button size, carbide grade and layout can be adjusted to drilling equipment and geological conditions.
