89mm T45 Retract Bit for Benching in Difficult Formations | MSD

Features & Benefits

• Unstoppable Performance: Combines the high productivity of an 89mm diameter with the security of a Retract skirt, allowing you to maintain drilling schedules even in fractured or unpredictable ground conditions where standard bits would get stuck.

• Enhanced Hole Straightness: The guiding splines of the Retract body provide superior directional stability, ensuring straighter blast holes over greater depths. This is critical for optimizing blasting results and improving safety.

• Powerful T45 Interface: The robust T45 thread is engineered to handle the high impact and torque from powerful drifters, ensuring that energy is efficiently translated into breaking rock, not lost to vibration or thread wear.

• Heavy-Duty Carbide Front: Equipped with a dense configuration of large, tough spherical tungsten carbide buttons, this bit is built to endure the punishing conditions of drilling in complex, abrasive rock without premature failure.

Recommended Applications

• Bench Drilling in Difficult Ground: The primary application for this bit. It is the definitive solution for open-pit mines and quarries that face challenges with fractured, weathered, or layered rock formations.

• Deep Hole Production Drilling: Highly recommended for production drilling where hole depths exceed 20 meters, as the Retract design significantly minimizes hole deviation and ensures easy retraction.

• Pre-splitting and Slope Stabilization: The exceptional hole straightness makes this bit a top choice for pre-splitting and slope stabilization projects, delivering clean, stable final walls.
