600mm DR6 Dedicated Rock Auger - Digga

Unyielding Strength: The Specialist for Solid Rock Boring

The Digga DR6 Dedicated Rock Auger is the pinnacle of drilling technology for operators who refuse to let solid stone stand in their way. Engineered specifically for the most punishing sub-strata, this 600mm auger is designed to penetrate non-fracturable rock, including reinforced concrete, high-grade basalt, and granite. Where standard earth or combo augers would simply bounce or wear prematurely, the DR6 utilises a heavy-duty cutting head equipped with rotating tungsten carbide rock picks that "graze" the rock surface, grinding it down with relentless efficiency.

Built to handle the immense torque of 5-tonne to 8-tonne excavators and high-flow skid steers, the DR6 features a robust 75mm square drive hub and a thick-walled centre tube for maximum structural integrity. The 600mm diameter is a substantial civil size, frequently utilised for large-scale bridge abutments, industrial foundation piers, and heavy infrastructure projects that require a deep, secure key into bedrock. Manufactured in Australia to endure the harshest site conditions, this auger ensures that even the toughest geology won't compromise your project timeline.

Compatible with Auger Torque S5 75mm Square Drive Hubs

Key Product Features

• Rotating Rock Picks: Features heavy-duty, rotatable tungsten carbide teeth that self-sharpen as they work, ensuring consistent cutting performance in high-PSI rock.

• Australian Made: Precision-engineered and manufactured locally to survive the absolute extremes of the Australian construction and mining sectors.

• 75mm Square Drive: Equipped with a heavy-duty reinforced hub designed to manage the high torque output of PD5 to PD8HF planetary drive units.

• Heavy-Duty Flighting: Constructed with thick steel flights and reinforced wear strips to resist the high levels of abrasion found in rock boring.

• Precision Rock Pilot: The heavy-duty pilot bit provides a secure anchor point, preventing the auger from "walking" or vibrating off-centre when starting a hole on hard stone.

• Optimised Spoil Lifting: The flighting pitch is meticulously designed to clear crushed rock fragments quickly, reducing heat build-up and protecting the integrity of the teeth.

Frequently Asked Questions

In what ground conditions should I use the DR6? The DR6 is a specialist tool for non-fracturable rock. It is the correct choice for solid sandstone, limestone, granite, and reinforced concrete. If you are drilling in a mix of earth and soft shale, the RC6 series may be faster, but for pure rock, the DR6 is the industry standard.

How do the rotating picks differ from standard teeth? Standard earth teeth are fixed, whereas DR6 rock picks are designed to rotate within their holders. This rotation prevents flat spots and ensures the tungsten tip wears evenly, effectively self-sharpening the tool to maintain maximum penetration speeds.

Can I use this auger on a standard-flow skid steer? While it may fit the hub, the DR6 requires significant torque and downward "crowd" pressure to be effective in rock. It is best paired with larger excavators or high-flow loaders equipped with a drive unit capable of 5,000Nm to 10,000Nm of torque.

Are the rock picks easy to replace? Yes. The picks are secured by heavy-duty retainers and can be swapped out quickly on-site with a Rotating Rock Pick Removal Tool (C123), also available from Earthmoving Warehouse. Regularly inspecting your teeth is vital to minimise downtime and ensure the auger body is not exposed to unnecessary wear.

Why Choose the DR6 Series?

When your contract involves drilling into the bedrock, you cannot afford to rely on "all-purpose" tools. The DR6 Dedicated Rock series provides the specialist mechanical advantage required to turn solid stone into spoil. By choosing Digga, you are investing in a tool that prioritises durability and operator efficiency, ensuring a professional finish in ground that would stall any other attachment.
