FAQ...
What Is a Rock Auger?
A rock auger is a specialized drilling attachment engineered for the excavation of hard and abrasive geological formations. Unlike standard augers, rock augers utilize replaceable teeth arranged strategically along the cutting edge to maximize penetration and rock fracturing efficiency.
These augers are typically manufactured from high-grade alloy steel, providing exceptional resistance to wear, impact, and torsional stress. Their robust structure allows them to operate effectively in harsh conditions where standard soil augers would fail.
Drillnova offers rock augers in a range of diameters and flight configurations
How Do You Install Auger Teeth?
Replacing auger teeth is a simple but critical maintenance procedure that ensures consistent drilling performance.
Removal: Insert a steel punch into the rear groove of the worn tooth and strike it with a hammer to dislodge it.
Installation: Slide the new tooth into the existing holder or drive lug until it locks into place with an audible “click”.
Securing: Tap the head of the tooth with a soft mallet. This seats the tungsten insert firmly and helps secure the tooth against vibration or slippage.
Drillnova augers are compatible with various standard tooth systems (e.g., BFZ, B47K, etc.), allowing easy replacement without specialized tools.
What types of augers are used in foundation drilling?
There are several types of augers designed for different ground conditions:
Rock auger – with bullet teeth for harder layers
Double-head auger – for increased efficiency in deep drilling
How to choose the right auger for your project?
Choosing the right auger depends on ground condition, pile diameter, and rig compatibility.
Use clay or sand augers for soft soil
Choose rock augers for mixed or abrasive formations
Ensure the auger matches your rig’s Kelly box and torque capacity
