All aspects of the Utility Series Rock Ripper® have been improved with the new design. Considerable attention has been paid in order to improve drilling rates and reduce vibration. The redesigned progressive-style Rock Ripper® allows the auger to “bite” into the rock which reduces the vibration while it increases drilling production.
The distinct attack angles paired with the STRATA™ series SR-76SW carbide drilling grade teeth are designed to cut through the rock, not grind it. The Utility Series Rock Ripper® is the auger to use for your utility rock drilling projects.
