45mm R32 Threaded Button Bit for Drifting and Tunneling | MSD

Features & Benefits

• Precision for Confined Spaces:The 45mm diameter is engineered for light, agile drill rigs, offering maximum control for complex cut patterns and precise hole alignment in narrow tunneling operations.

• Efficient Energy Transfer:Our robust R32 thread interface is precision-machined to ensure a flush, secure connection to the drill string, maximizing the impact power delivered to the rock face.

• Advanced Carbide Engineering: Features strategically placed spherical tungsten carbide buttons, designed to not only maintain high penetration rates but also to ensure uniform wear. This extends the bit's effective service life and reduces the frequency of regrinding.

• Superior Cuttings Evacuation: The design incorporates strategically placed flushing holes to create optimal airflow and evacuate cuttings efficiently. This prevents regrinding of chips, reduces heat at the bit face, and ultimately improves overall drilling productivity.

Recommended Applications

• Underground Drifting and Tunneling:As the primary application, this bit excels in creating blast holes for development drifts. For optimal performance in medium-hard rock, pair with a high-frequency hydraulic drifter.

• Rock Bolting and Ground Support: Its exceptional hole straightness makes it a highly reliable tool for ground support systems. Ensure proper flushing to maintain hole integrity for easier bolt installation.

• Small-Hole Production Drilling: Ideal for situations requiring smaller diameter blast holes in small-scale mining or dimensional stone quarrying operations.
