Rock Auger S4-100 mm

The GORE S4 Rock Range is built for professionals who take on the toughest drilling environments — where mixed-ground tools can’t compete and failure isn’t an option.

Engineered from high-grade, heavy-wall steel with a reinforced core and aggressive spiral profile, every GORE Rock Auger delivers maximum penetration, stability, and control in extreme conditions.

Bullet-style rock picks and a hardened rock pilot are designed to fracture and cut through solid substrates including hard rock, shale, concrete rubble, and high-compression stone.
This is the auger you choose when the ground isn’t just difficult — it’s unforgiving.

When you’re drilling directly into solid rock, the GORE Rock Range is the standard.

Standard hub: 65 mm round.
