3M STIKIT SANDING DISC GOLD Adhesive backing allows for quick application and easy removal. Convenient disc rolls eliminate the need to remove disc liners from individual discs. Aluminum oxide mineral is durable, cuts fast, and performs well on many surfaces. Load-resistant coating helps prevent premature loading of the disc surface to maximize cut and extend the life of the abrasive grains. Strong, C-weight paper backing provides extra durability when compared to lighter weight paper backings. Sold by each or roll of 100.
