The Arbortech TURBOPlane™ is a universal wood shaping blade that can be used to create different shapes, profiles, and finishes. Simply attach it to the Power Carving Unit™ or a standard 100mm (4″) or 115mm (4 1/2″) grinder and it can be used flat to create large level surfaces, or used at angles to provide shallow cuts for fine shaping, planing, and sculpting.
