471 General DIG-R-TACH 4710 Series Earth Augers

The 4710 Series Earth Augers from the DIG-R-TACH lineup bring serious torque, serious strength, and serious digging power to your jobsite. Designed to drill holes up to 36 inches in diameter and 36 inches deep with the option to go even deeper using extensions, these augers are the definition of heavy-duty. Engineered for fast soil penetration and maximum dirt removal, they make light work of the toughest conditions, so you don’t have to. Built for professionals who need performance that matches their pace, the 4710 Series gets it done fast, clean, and reliably.

FEATURES

• 2.0 INCH HEXAGON AUGER DRIVE CONNECTION: Provides a high-strength, secure fit for maximum torque transfer. Withstands extreme digging forces without slippage or wear, ensuring long-lasting connection integrity.
• FORMED, STEEL PLATE BORING HEAD: Precision-engineered to position cutting teeth at optimal angles for aggressive soil penetration. Improves wear life and enhances digging efficiency in tough ground conditions.
• FLIGHTING PITCH MINIMIZES POWER REQUIRED, MAXIMIZES LOOSE SOIL REMOVED: Efficiently lifts material out of the hole while reducing resistance. Keeps holes cleaner with less fallback and minimizes operator fatigue by doing more of the work.
• HEAVY-GAUGED, STEEL, HELICOID OR SECTIONAL FLIGHTING: Built to take on rocky, compacted soils without bending or distortion. Designed to resist wear over time and hold strong through repeated high-torque operations.
• HEAVY-WALLED, STEEL, AXLE: Provides the backbone for the auger, resisting both bending and torsional stress. Ideal for high-impact digging with large diameter bits and dense soil.
• OUTSIDE CUTTING TEETH EXTEND PAST FLIGHTING EDGE: Reduces direct wear on the flighting and protects it over time. Extends auger life and ensures cleaner hole edges by slicing through soil and debris more effectively.
• WIDE SELECTION OF INTERCHANGEABLE CUTTING TEETH: Allows you to match your auger to the conditions at hand—from loose loam to rocky clay. Increases productivity by giving you the right cutting edge for every job.
