- Digga-designed Eaton motor eliminates the need for bulky valve blocks while reducing many potential leak points
- 2-piece shaft design ensures maximum side load ratings without increasing load on bearings
- Integrated PRV (Pressure Relief Valve) to prevent damage to internal motor on kickback
- Compatible with vehicles that put out 20-53 GPM of hydraulic flow at up to 3500 PSI

- Compact, high-torque Digga-manufactured gearbox generates a whopping 20,309 ft-lbs of Torque
For years, Digga has held its position as the forefront leader in Auger technology. Now, it takes a monumental leap forward with the introduction of the introduction of the HALO Auger Alignment system. This cutting-edge technology revolutionizes drilling and piling operations by giving the operator a visual indicator of their drilling angle, eliminating the need for a spotter, and ensuring all holes drilled are plumb.
- Minimize Fuel Consumption. Host machines can be run at a lower RPM on certain drilling jobs to save fuel.
- Drill More Efficiently. 2-Speed Drives allow you to match your torque profile to the perfect profile for your host machine.
