Fab Auger Bits - For Light Duty Digging

Fab auger bits feature a durable fabricated boring head with hardened, bolt-on teeth and a fishtail point for reliable performance. Designed for light to moderate ground conditions—such as loamy or sandy soils—these bits deliver cost-effective solutions for general digging applications without compromising quality.

Cast Auger Bits - For Heavy Duty Digging

Cast auger bits feature a rugged cast steel boring head with hardened, drive-in teeth and a fishtail point for maximum durability. Built tough for difficult ground conditions including fracturable rock, asphalt, frozen ground, heavy clay, and compacted soils—making them the ideal choice when the job demands strength and reliability.

Bullet Rock Auger Bits

Bullet Rock auger bits are engineered with carbide bullet-style teeth for maximum cutting power in the toughest conditions. Ideal for solid rock, concrete, fracturable rock, asphalt, frozen ground, and compacted soils, these bits deliver superior penetration and durability where standard designs fall short.

Trees & Shrub Auger Bits

Tree and shrub auger bits feature a fabricated boring head with hardened, bolt-on teeth and a hardened fishtail point for dependable performance. The stepped flighting design creates extra clearance, promoting healthy root growth—making these bits ideal for landscaping and planting applications.

2" Rock Drill Bit

Our rock drill bits are designed for precision in solid rock conditions. Perfect for piloting holes or setting T-posts in solid rock, these bits deliver the strength and reliability you need for demanding applications.

Stump Auger Bits

The Danuser Stump Auger eliminates stumps quickly without the need for large, specialized equipment. Its threaded pilot bites into the stump, while oversized cutting blades shave it away with ease. For extended service life, the blades can be reversed and sharpened—delivering long-lasting performance and cost efficiency.

Wobble Auger Bits

The Danuser Wobble Auger creates a hole with a slight flare at the top and a compacted base—leaving no loose dirt to deal with. This patented design is the ideal solution for installing posts with concrete, rock, or other fill material instead of backfilling with dirt. By rotating off-center, or “wobbling,” the auger compacts soil to the sides and bottom of the hole for a stronger, more stable foundation.
