Stacked dados cut a smooth and precise groove either across or with the grain in all types of woods, plywood, and composite wood materials. This set contains two outside cutting blades that have a tooth pattern of five beveled cutting teeth for a clean, crisp cut followed by a straight raker tooth. The five Chipper blades combine with the two outer Side-Cutting blades to cut grooves from 1/4" through 13/16". the anti-kickback tooth profile prevents the blade from being fed material too quickly improving safety.
