When drilling in soil that is self-supporting when cut, use the Ultra X3 375 10-in (25-cm) mix reamer x pull eye. The mix design efficiently cuts the 10-in (25-cm) diameter hole. Ream and pull back product at the same time with the pull eye included.

The Ultra X3 375 drill system is the largest of the sizes offered at this time. A non-torqued spline connection system optimizes the time it takes to perform tooling switches — without the need for special tools or breakout devices — and offers compatibility with a wide range of pilot bits and pullback configurations.
