Pearl Redline CBT Trimmable Flap Discs

Pearl Abrasive Redline CBT Trimmable Maxi Disc is made from a high quality ceramic aluminum oxide.  This type of abrasive grain features a fine crystalline structure which allows for fracturing while cutting.  The micro fractures allow the abrasive grain to form new cutting edges, so this flap disc sharpens itself throughout its entire lifetime.
