The 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 any standard 115mm (4 1/2") or 125mm (5") angle grinder with a 5/8" spindle. and it can be used flat to create large level surfaces, or at angles to provide shallow cuts for fine shaping, planing and sculpting.
