900mm A4 Tungsten Auger - Digga

Maximum Wear Resistance for Large-Diameter Drilling in Abrasive Soils

The 900mm Digga A4 Tungsten Auger is the ultimate high-capacity solution for operators needing to drill massive holes in ground conditions where standard teeth simply won't last. While regular Earth teeth are suitable for clean loam, this Tungsten Carbide (TC) model is purpose-built to withstand the extreme friction of sandy soils, grit, and abrasive light clay. Engineered for mini loaders and excavators up to 5 tonnes, it provides the long-life performance required for large foundation piers, significant landscaping features, and commercial construction.

This heavy-duty auger features a reinforced centre shaft and 8mm thick high-grade steel flights with a double-start design to move massive amounts of spoil efficiently. The Tungsten Carbide (TC) teeth offer superior wear properties, staying sharp and effective for significantly longer than standard steel teeth in abrasive environments. With DiggaÔÇÖs "True Cut" engineering, you are guaranteed a precise 900mm hole diameter from top to bottom.

Frequently Asked Questions

Why is Tungsten (TC) better for abrasive ground? Tungsten Carbide is significantly harder than standard steel. In "soft" but gritty soils like sand, standard teeth can actually sand down and lose their edge rapidly. TC teeth resist this abrasion, maintaining their shape and cutting efficiency for much longer.

Which drive hub do I need for my machine? This depends on your specific drive unit. We offer the A4 range in 65mm Round, 50.8mm Round, 50.8mm Hex, and 57mm Square hubs. Please check the output shaft of your drive motor before ordering to ensure a perfect fit.

Which machines can use this A4 900mm Tungsten Auger? It is compatible with mini excavators, skid steers, and mini loaders ranging from 750kg up to 5 tonnes, provided the drive unit matches one of our four available hub sizes and has sufficient torque for a 900mm diameter.

Are the teeth replaceable? Yes. The TC teeth are part of the TRULOC system, allowing for quick and easy replacement if they eventually wear down, keeping your auger in peak working condition.
