The GORE S4 Rock Range is built for professionals who drill where others stop — into solid rock, dense shale, and concrete rubble. When mixed-ground tools fail, the S4 Rock Auger keeps driving forward.
Engineered from high-grade, reinforced steel with a constant spiral profile, the S4 delivers controlled penetration and steady spoil removal even in extreme ground conditions.
A hardened rock pilot combined with heavy-duty rock picks fractures hard substrates with precision and power, turning the toughest terrain into workable ground.
Choose the Rock Range when you need uncompromising strength — true bedrock capability.
Standard hub: 65 mm round.

Great breaker for the price
Fits my CAT 308 perfectly. Easy to install and the power is excellent. Our go-to breaker on the job site.
