The tooth cutting angle ensures spoil is broken up thoroughly to avoid any clogging.

    • Flat Boring Head Option

      The Flat Hard Rock Auger creates a flat-bottomed hole while still delivering high cutting power with hard rock pick teeth and pilot.

    • Rock Pilot and Teeth with rotating rock picks

      The hard rock augers are offered with our rotating rock teeth and pilots. Designed so only the rotating picks wear not the pockets/ holders.
