    Rugged, in your face digging prowess. Best-in-class, heavy-duty construction meant to deliver real performance in the toughest soil conditions.

    Every inch, from the drive hub and flighting to the boring head is designed to provide exceptional wear and a long service life. We don t cut corners. Many try to copy but can t hold a candle to these. Screw bits penetrate quickly and keep your dig centered so the hole doesn t look like you were digging sideways in a windstorm. Teeth attack angles are positioned for optimum soil break up and faster penetration. Flighting pitch is set to lift dirt up and out to minimize dirt fallback saving you time. Multiple, interchangeable tooth options available depending on the conditions you dig. Just an auger, think again. Made to last, made to dig, made for you right here in the USA.

    Features/Benefits:

    • 1.375-inch hexagon auger drive connection
    • Flighting pitch minimizes power required, maximizes loose soil removed from hole
    • Heavy-gauged, steel, helicoid or sectional flighting for added structural strength
    • Heavy-walled, steel, axle to better withstand bending and torque loads
    • One piece, cast steel boring head positions teeth for optimum digging performance, wear & service life
    • Outside cutting teeth extend past flighting edge to minimize flighting wear & extend service life
    • Wide selection of interchangeable cutting teeth for added flexibility to match soil conditions
