3M™ Disc Pad Face Plate Ribbed provides the firm support required for grinding applications. This upgraded product features a one-piece design that helps reduce the chances of losing parts around the shop. Recommended for use with 36+ grit 3M™ Cubitron™ II Fibre Disc 982CX Pro, with ribs that increase unit pressure and optimize abrasive performance.The 3M Disc Pad Face Plate Ribbed is ribbed around the entire face, which increases unit pressure when grinding. This extra pressure helps optimize fracturing of the 3M Precision-Shaped Grain in our 3M Cubitron II Fibre Discs, leading to improved cutting speed and product life. Match the disc back-up pad to the application: for lighter grinding and finishing applications, choose a disc pad with a lighter density. For heavy grinding with coarse grade discs, choose the 3M Disc Pad Face Plate Ribbed. The extra hard, stiff density of this upgraded back-up pad is the ideal solution when beveling and grinding large welds.
