Dirt and Rock augers for skid steers and mini-excavators

Take on the toughest drilling applications with a Star Industries Heavy Duty Auger. Just like our rugged planetary drive units, these augers are constructed from heavy duty, high-grade materials giving them the strength to handle any drilling job (even solid rock).

Rock Auger

Our most rugged auger for your most difficult drilling conditions. These augers are designed for solid rock, concrete, fractured rock, frozen ground and compacted soils. Larger 8″ to 36″ dia. augers feature a bolt in 1¾” shaft pilot, reinforced ¾” bottom flight boring head with Rockwell 65 hard facing, replaceable carbide bullet teeth and double flighting on 3½” high strength tube. Smaller 6″ dia. augers feature a welded pilot, replaceable carbide bullet teeth and double flighting on 3½” high strength tube. Available in 6″ – 36″ diameter.

Choosing a Diameter

Rock drilling takes more torque than dirt. The 10-20 GPM drive handles rock augers up to 24″; the 15-30 and 20-35 GPM drives handle up to 36″. For general soil, the Star Heavy Duty Single Flight Auger Bit digs faster and costs less. Keep spare carbide teeth on hand when drilling rock.
