These new Trizact grinding belts are fantastic for sharpening your carving tools. Structured aluminum oxide abrasives feature an eningeered surface of microscopic three-dimensional structures resembling pyramids. This precise and consistent surface is ideal for final sharpening applications (use our coarse grits for repairing or removing metal). This new surface not only cuts quickly but also prevents clogging. Trizact belts last up to 5 times longer than conventional grinding belts. 1" x 42"
