Engineered for ultra-rapid cut on carbon steel, 3M™ fiber disc 782C features 3M™ precision shaped grain. With its outstanding cut, durability and ease of use, this disc offers a major step up in performance over conventional fiber discs. Advanced abrasive technology makes it an excellent choice for tough applications including weld removal, blending and finish refinement. Balance cost and output by selecting the abrasive with precisely the right amount of cut and life, no more and no less. 3M™ fiber disc 787C contains precision shaped grain (PSG) to optimize the balance of speed and longevity for many of your carbon steel operations. Disc construction includes a stiff fiber backing and strong resin bond that provide durability and tear-resistance, which along with fast-cutting abrasive grain enables operators to complete more parts per disc and requires fewer disc changes. The exceptional life and cut of our 782C fiber disc make it one of 3M™ best grinding discs for high production environments, providing significant gains over conventional fiber discs. When our highest tier fiber disc may be under-utilized but productivity is still your bottom line, our 782C fiber disc delivers outstanding througHPut. This fiber disc is an excellent choice for a range of applications such as edge chamfering, beveling, deburring and weld removal. Developed for improved output on light to heavy stock removal, 3M™ precision shaped grain lets operators finish tough tasks faster and with less fatigue. Because the grain wears evenly and stays sharp, PSG abrasives last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications. To accomplish this level of performance, 3M™ engineers apply proprietary microreplication technology to create precise triangular structures of 3M™ ceramic abrasive grain and then electrostatically orient them on the backing to form sharp peaks. These ultra-sharp peaks slice cleanly through metal rather than gouging or \"plowing\" as conventional abrasives do and continuously self-sharpens as the points break off. To suit many different project needs, we offer these discs in a range of sizes and a variety of attachment styles. We offer 7/8 in center hole (CH) discs that require the use of a 3M™ disc pad face plate and 3M™ hub. This ensemble is attached to a right angle grinder with a disc retainer nut (all sold separately). Also available are GL and TN style discs with convenient built-in fasteners to provide reliable attachment to the tool and easy disc changes between applications. Smaller sized discs with quick-change attachments are sold separately as 3M™ Roloc™ fiber disc 782C. Fiber discs are heavy duty abrasives that feature a tough, stiff backing made from vulcanized fiber that resist wear and can handle tough grinding applications. For optimal performance, the disc should be used with a face plate of the appropriate density for the application - a lighter density face plate for lighter weight grinding applications and a harder density face plate for more heavyweight grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will re-sharpen, maximizing the life of the abrasive. 3M™ abrasives engineers know abrasive construction. For more than 100 years 3M™ has been a leading abrasive supplier for the metalworking and woodworking industries and we offer a complete line of high quality metalworking abrasive solutions to meet your tough jobs. Our 3M™ fiber disc 782C is designed to enable operators to take production to the next level by completing more work in less time. It is a prime example of how 3M™ science provides advanced solutions to help industrial businesses operate faster, better and more efficiently. 3M™ 7100109880, Close Coated, 7 in Diameter Disc, 7/8 in Center Hole, 36+ Grit, Ceramic Abrasive, Fiber Backing, Arbor Attachment, Applicable Materials: Aluminum, High Nickel Alloys, Stainless Steel, Titanium and Zirconium, 8600 RPM Maximum, Maroon
