The Mini TURBO™ is designed to fit the Power Carving Unit™ or any standard 4" (100mm) or 4 1/2" (115mm) angle grinder with a 5/8" spindle. This is an ideal tool to be used freehand or with guides and templates for accuracy. The blade size and extended shaft make previously impossible cuts and shapes now possible. The kit also provides the ability to convert the Mini TURBO™ into an effective sanding tool, making it perfect for medium sized sculpting projects from start to finish.
