RBG 785 Orange Grinding Flap Wheel is designed specifically for the RBG 750 & RBG 950 grinders to restore mulching blades to a 'from the factory' edge. The Flap Wheel sharpens blades with waves or curves such as mulching blades. Made with a durable ceramic resin fiber and epoxied to a steel plate for ultimate durability. This aggressive 24 grit ceramic material cuts grinding time and minimizes grinding wheel dust compared to traditional grinding wheels. The wheel peels the steel away from the blade, leaving less residual material and giving you a cleaner shop. Size 7" x 5/8". GTIN 00850039208089
