100mm A4 Tungsten Auger - Digga

Superior Wear Resistance for Abrasive Soils and Long-Life Performance

The Digga A4 100mm Tungsten Auger is the upgraded choice for operators seeking maximum tooth longevity in soft but abrasive ground conditions. While standard Earth teeth are economical, this Tungsten Carbide (TC) model is engineered to withstand the constant friction of sandy soils, grit, and light clay without losing its cutting edge. Designed for mini loaders and excavators up to 5 tonnes, it provides a "set and forget" solution for high-volume fencing and landscaping projects.

This model features a heavy-duty centre shaft and 8mm thick high-grade steel flights with a double-start design. The Tungsten Carbide (TC) teeth offer significantly better wear properties than standard Earth teeth, ensuring the auger stays productive for longer periods between maintenance. With Digga’s "True Cut" engineering, the 100mm diameter is maintained throughout the depth of the hole for a perfect, professional finish every time.

Frequently Asked Questions

Why choose Tungsten (TC) over standard Earth teeth? While Earth teeth are great for clean garden soil, TC teeth are essential if your "soft" ground contains sand or grit. The Tungsten Carbide tip is much harder than steel, meaning it won't blunt as quickly in abrasive conditions.

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 100mm 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.

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, ensuring your auger always maintains its cutting efficiency.
