Auger Bits & Accessories | Auger Bit for Tractor & Skid Steer Drilling

Dirt, rock & tree auger bits in sizes from 4” to 42”.

Our auger lineup covers everything from small pilot holes to large-diameter tree and foundation drilling. Whether you are running a skid steer or looking for an auger bit for tractor applications, we stock industrial-strength options designed for real work. Our lineup includes:

• Dirt auger bits (4”–36”): Built for fencing, deck footings, sign posts, and general construction drilling in standard soil conditions. Our Heavy-Duty Double-Flight Dirt Augers are available from 4” up to 36”, including 24” configurations that work well for skid steer fencing setups and higher-volume post drilling.
• Rock auger bits with bullet teeth and carbide options: Designed for limestone, caliche, shale, and compacted terrain where standard dirt teeth wear quickly. Our Premier Rock Auger Bits – Bullet Tooth configurations use reinforced flighting and aggressive carbide cutting edges to maintain penetration in abrasive soil conditions.
• Rock auger bit – 2” carbide “puff” configuration: For operators drilling in extremely dense or fractured rock, the Premier 2" Carbide Puff Auger Bit provides concentrated cutting pressure and durability where broader dirt teeth would bounce or dull prematurely.
• Tree auger bits (18”–42”): Ideal for landscapers, nurseries, and property development crews installing larger root balls efficiently and cleanly. Our Premier Tree Spade Auger Bits are designed to remove soil evenly while maintaining hole structure for proper backfill and root placement.
• Stump planing auger bits (12” & 16”): Engineered for grinding and leveling stumps without switching machines, the Premier Stump Planer Bit offers a practical solution for controlled stump reduction using an auger drive.
• Auger output shaft adapters and conversions: To ensure proper compatibility between your auger drive and bit, we stock multiple configurations of Auger Output Shaft Adapters, helping prevent wobble, protect bearings, and allow torque to transfer efficiently during drilling.
• AMFG Concrete 4 Cu Ft Auger Mixer: For crews pouring footings immediately after drilling, the AMFG Concrete 4 Cu Ft Auger Mixer allows on-site mixing without waiting on third-party delivery. One machine drills. One machine mixes. Less downtime between operations.

Auger bits for fencing, tree planting and foundation drilling.

These auger bits are used daily across agricultural, landscaping, and commercial construction projects because once torque is applied, durability is everything.

• Contractors drilling long fence runs rely on straight shafts and reinforced flighting to prevent wobble and excessive vibration.
• Ranchers setting corner posts need an auger bit for tractor use that maintains structural integrity under repeated load cycles.
• Tree planting crews depend on larger diameter bits that create consistent root cavities without collapsing the hole walls.
• Foundation and pier drilling operators require depth stability and rock-capable teeth that hold up in abrasive ground.

The right bit reduces stalled drilling, protects your drive unit, and keeps labor moving.

Industrial-strength auger equipment built for Texas rock.

We stock Premier dirt and rock auger bits manufactured in Indiana to industrial capacities because light-duty drilling equipment does not survive here.

Limestone exposes weak welds. Caliche exposes soft teeth. Compacted soil exposes poor shaft alignment.

That is why our auger bits are built with reinforced flighting, high-grade shafts, and carbide tooth options designed to withstand repeated drilling in abrasive terrain. Whether you are running a skid steer or looking for an auger bit for tractor applications, structural integrity and proper torque transfer matter once pressure is applied.

We are trained technicians and equipment specialists — not order takers. We maintain strong inventory and ship directly from our Marble Falls facility. If you ever have compatibility questions or need technical guidance, our team is available to help before and after purchase. We service what we sell and stand behind our equipment.

If it does not hold up in Texas rock, we do not carry it.
