Description
The "True Cut" Guarantee: Stinger Auger Bits are engineered for precision. While inferior bits wobble and create cone-shaped holes (wasting concrete), Stinger's True Cut Design ensures that a 12-inch auger drills exactly a 12-inch hole. Combined with Shallow Pitch Flighting, these bits remove spoil efficiently without clogging, even in sticky clay.
Select Your Soil Type:
• A6 Earth Series: Features bladed teeth and a heavy-duty tube. Ideal for drilling dirt, clay, and shale.
• RC6 Combo Series: The ultimate all-rounder. Equipped with Taper Teeth (Tungsten) to rip through mixed rocky ground and frozen earth.
• DR6 Rock Series: The heavy hitter. Features rotating Rock Picks and extra-thick 5/8" flighting to fracture solid rock and concrete.
