102mm T51 Threaded Bit for Heavy-Duty Production Drilling | MSD

Features & Benefits

• Maximum Rock Breaking: The large 102mm (4") diameter is designed for high-volume blast holes, maximizing the explosive charge per hole and optimizing fragmentation for easier loading and crushing.

• Heavy-Duty T51 Thread: The T51 thread provides an exceptionally robust and rigid connection, capable of withstanding the immense impact power and high torque of heavy-duty hydraulic drifters without premature failure.

• Engineered for Endurance: Features a massive, durable bit body and a dense configuration of large spherical tungsten carbide buttons, built to endure long hours of continuous, high-impact drilling in the toughest conditions.

• Unrestricted Flushing: A high-capacity flushing design with multiple large air holes ensures that the vast amount of rock cuttings is cleared instantly, maintaining maximum penetration speed and protecting the bit from excessive heat and wear.

Recommended Applications

• Heavy-Duty Production Drilling: The definitive application for this bit. It is the workhorse for large-scale quarries and open-pit mines aiming for the highest possible production rates and lowest total drilling cost.

• Large-Scale Construction and  Infrastructure: The ideal tool for major civil engineering projects, such as dam foundations, major highway cuttings, and large-diameter pipeline and utility bores.

• Underground Production (Large Drifters): Suitable for large-scale underground production drilling (stoping) where powerful drifters and a 102mm hole size are utilized.
