64mm T38 Retract Threaded Bit for Difficult Rock Conditions | MSD

Features & Benefits

• Specialized Retract Design: The defining feature of this bit is its Retract (retractable) skirt with splines. This design actively assists in retracting the drill string, significantly reducing the risk of getting stuck in fractured or unconsolidated rock.

• Enhanced Hole Straightness: The Retract body acts as a guide in the hole, improving straightness during long-hole drilling and deep benching operations, which is critical for effective blasting.

• Robust T38 Thread Interface: A proven T38 thread ensures a strong connection to medium-power drifters, delivering the consistent impact energy needed to overcome challenging geological conditions.

• Durable Carbide Front: Equipped with tough spherical tungsten carbide buttons, this bit is engineered to maintain its cutting structure and resist premature wear even in complex and unpredictable rock formations.

Recommended Applications

• Fractured and Unconsolidated Rock: The primary application where this bit excels. It is the go-to solution when standard bits face a high risk of getting stuck, saving valuable time and preventing tool loss.

• Deep Bench and Long-Hole Drilling: Highly recommended for applications where maintaining hole straightness over long distances is a top priority, such as in underground production or pre-splitting for construction.

• Drilling in Variable Ground Conditions: An excellent all-around choice for job sites where the rock formation changes frequently, providing an extra layer of operational security.
