89mm T45 Threaded Button Bit for High-Productivity Benching | MSD

Features & Benefits

• The Industry Sweet Spot: The 89mm diameter is widely regarded as the sweet spot for medium-sized bench drilling, offering a perfect blend of high penetration rates and optimal blast hole spacing for excellent fragmentation.

• Built for Powerful Rigs: The robust T45 thread is designed to withstand the high torque and impact power of modern hydraulic drifters, ensuring maximum drilling performance and reliability.

• Maximized Service Life: Features a heavy-duty bit body and a dense configuration of large spherical tungsten carbide buttons, engineered to resist wear and breakage in long, demanding drilling shifts.

• Superior Flushing Capacity: A high-capacity flushing design with multiple air holes ensures that the large volume of cuttings from the 89mm hole is cleared quickly, maintaining high speed and reducing wear.

Recommended Applications

• Production Bench Drilling: This bit's primary application. It is the workhorse for most medium-sized quarries and open-pit mines, delivering consistent and cost-effective performance day in and day out.

• Large-Scale Construction: An excellent choice for major construction and infrastructure projects that require a large number of blast holes, such as highway construction and dam sites.

• Pre-splitting: The stable and predictable performance of this bit makes it suitable for pre-splitting applications where a larger hole diameter is specified.
