In high-stakes rock drilling operations, hole deviation significantly impacts profitability. The H22-643/108-610-40 6.5° Reaming Guide Rod is engineered to eliminate deviation in large-diameter long-hole drilling, enhancing efficiency across the world's most demanding mining and infrastructure projects.
This precision tool is specifically designed to maintain straight drilling paths in challenging environments, from the deep underground copper mines of Zambia and South Africa to the ultra-hard rock formations of Siberia (Russia) and Canada.

The 6.5° taper design creates a rigid, unified connection between the pilot guide rod and reaming bit. This structural stiffness eliminates joint play, ensuring the drill string maintains a perfectly straight trajectory during deep-hole stoping and raise boring operations.
Manufactured from ultra-high-strength alloy steel, the rod undergoes full-body carburization and state-of-the-art shot peening. This dual heat-treatment process creates a highly wear-resistant outer skin while retaining a flexible, shock-absorbing inner core to handle extreme rotational torque.
The generous internal flushing hole allows for high-velocity water or air delivery. Fast flushing ensures that heavy rock chips are evacuated immediately from the cutting face, preventing energy-wasting secondary crushing and reducing carbide button overheating.
As a trusted global supplier of premium rock drilling tools, we manufacture our reaming guide rods to match or exceed OEM specifications. By optimizing our supply chain, we offer direct industrial replacement parts that drastically reduce your cost-per-meter without compromising on tool life.
