Conical Rock Auger

Conical Rock Auger

Categories: ,

Description

The Conical Rock Auger is a heavy-duty drilling tool engineered for efficient penetration of hard soil formations, weathered rock, fractured rock, and bedrock. Its tapered design enables progressive cutting action, reducing drilling resistance while improving hole accuracy and productivity.
Equipped with high-strength wear-resistant steel and premium bullet teeth, the auger delivers excellent performance in demanding foundation and piling applications. The conical profile allows material to be broken and lifted efficiently, making it suitable for bored piling and deep foundation projects.
