Founded in 1993, Dura-GRIT is known for its high-quality and long-lasting carbide sanding tools and Dremel drill power carving burrs. Made in North America from tungsten carbide and steel, Dura-GRIT tools last 100x longer than sandpaper, making them the most versatile and durable cutting and shaping tools on the market! This 5-pc. Carbide Cutting Wheel Set comes with five of the most powerful, long lasting cutting and shaping wheels available for hi-speed, 1/8 chuck drills. They can be used to cut, carve and drill the following materials: modelling plywood, bass wood and balsa etc., fiberglass sheets and molded parts, composites, carbon fiber rods and sheets, ABS parts, PVC items, rubber, leather and more! This set includes a 1-1/2" 60-grit cutting wheel (cuts material up to 5/8" thick quickly and cleanly); a 1-1/4" 60-grit carbide cutting/shaping wheel (cuts up to 1/2" deep); a 1-1/4" 60-grit carbide mushroom shaping wheel (gives you rapid material removal and a smooth sanded finish in one operation); a 1" 80-grit cutting wheel (cut and sand to a smooth finish in one step); and a 1-1/4" dia. x 1/16 (1.6mm) wide carbide non-sanded grout removal wheel (great for smaller jobs that don't require larger, more expensive power tools). This set saves you time and money, giving you more time for creativity and more detail to your finished product. The grit doesn't tear loose so it is a "green" alternative to sandpaper. Not recommended for use on metal.
