V-Style plates feature a special cut on the leading edge (or cutting edge). This edge is cut at two successive 45° angles to roughly simulate
a spiral. This is in addition to the 45° bevel on the leading edge which is a standard feature for helix plates of both styles. V-Style plates
are appropriate for use in applications where rocky or rubble-filled soils are anticipated, or where very dense layers need to be penetrated.
Some smaller plate diameters indicated by an asterisk (*), are not typically available in a V-Style.
