This Tornado Reamer has a 22" cutting diameter and a connection type of 3-1/2" IF Box/Box. This Melfred Borzall original design combines aggressive cutting and mixing to reduce pullback and rotational forces. Tornado is ideal for sticky clays and reactive soils but can also be used very successfully in a variety of conditions from sand to hardpan.
