3M Disc Back-up Pads provide the firm support required for grinding applications. This new 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. Ribbed Design for Higher Pressure For optimal abrasive performance, it€™s important to choose the right disc back-up pad for your application. This 3M Disc Back-up Pad 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. Added Stiffness for Heavy Grinding Match your disc back-up pad to your application: for lighter grinding and finishing applications, choose a disc pad with a lighter density. For heavy grinding with coarse grade discs, choose our 3M Disc Back-up Pad Ribbed. The extra hard, stiff density of this upgraded back-up pad is the ideal solution when beveling and grinding large welds. The Full System Advantage 3M Disc Back-up Pad Ribbed is part of a complete right angle system. When you combine this upgraded disc back-up pad with 3M Cubitron II Fibre Discs or select Scotch-Brite Abrasives, and a 3M Pneumatic Angle Grinder, you€™re setting yourself up for a new level of productivity. When used together, the effectiveness of each component is enhanced to provide optimal abrasive performance €” including abrasive life, cut-rate and consistency. 7100362610 - 00068060112330
