350mm A8 Multi-Faceted Tungsten (MFT) Auger - Digga

Engineered Excellence: The High-Performance Multi-Faceted Tungsten Specialist

The Digga 350mm A8 MFT (Multi-Faceted Tungsten) Auger is the definitive choice for operators who demand speed and efficiency when drilling through diverse ground conditions. Specifically designed for high-torque environments, this 350mm auger excels in heavy earth, stiff clays, and shale strata. The MFT cutting head features a unique tooth design that provides multiple cutting edges, allowing the auger to "break" through tougher layers where standard earth teeth might struggle, all while maintaining the rapid spoil removal required for high-production projects.

Built to withstand the significant power of 8-tonne to 20-tonne excavators and high-flow loaders, the A8 series is constructed with a heavy-duty 75mm square drive hub and a reinforced centre tube. The 350mm diameter is an essential size for commercial fencing, substantial structural footings, and utility installations in challenging soil profiles. Manufactured in Australia to exacting standards, the A8 MFT ensures that your machinery's torque is converted into pure drilling performance, regardless of the terrain.

Compatible with Auger Torque S6 75mm Square Drive Hubs

Key Product Features

• MFT Cutting Head: Equipped with Multi-Faceted Tungsten teeth that provide superior penetration in shale and compacted soils compared to standard flat teeth.

• Australian Made: Precision-engineered and manufactured locally to survive the harshest site conditions in the Australian construction industry.

• 75mm Square Drive: Features a reinforced hub designed to handle the high torque output of PD8HF to PD22 planetary drive units.

• Efficient Flighting Pitch: The steel flights are pitched to maximise spoil removal, reducing the drag on your drive motor and improving fuel efficiency.

• True Cut Technology: Digga’s signature design ensures a precise 350mm hole diameter is maintained, preventing over-drilling and saving on concrete costs.

• Tungsten Pilot Bit: Features a heavy-duty tungsten-tipped pilot that prevents the auger from "walking" and ensures accurate hole placement in hard ground.

Frequently Asked Questions

What are the best ground conditions for an A8 MFT Auger? The A8 MFT is highly versatile. It is specifically designed for earth, clay, and fracturable shale. While it is tougher than a standard earth auger, for solid, non-fracturable rock, we recommend moving to the RC8 or DR8 series.

Why choose MFT teeth over standard earth teeth? Multi-Faceted Tungsten teeth feature several cutting faces. This allows them to stay sharper for longer and break up harder ground materials more effectively, which reduces the downward "crowd" pressure required from your machine.

Is this auger compatible with my 75mm Square drive? Yes, the 75mm square drive is the standard fitment for the Digga PD8HF to PD22 auger drives and is fully compatible with S6 Auger Torque drive units and most 8t–20t excavator drive motors.

How often should I replace the teeth? You should inspect your teeth before every job. If the tungsten inserts are chipped or worn flat, they should be replaced to prevent wear on the auger’s pocket and to minimise drilling time. Spare MFT teeth are easily fitted on-site with a simple pin and clip system.

Why Choose the A8 MFT Series?

When you need a reliable, high-speed drilling solution that bridges the gap between earth and rock tools, the A8 MFT is the professional’s preference. It offers the perfect balance of aggressive cutting and rapid spoil lift, ensuring your site stays productive and your machinery operates at peak efficiency. By choosing the A8 MFT, you are investing in a durable, Australian-built attachment that prioritises performance in every rotation.
