Engineered for ultra-rapid cut, 3M™ Fibre Disc 787C features 3M Precision Shaped Ceramic Grain. With its outstanding cut, durability and ease of use, this disc offers a step up in performance over conventional fibre discs. Constructed with a grinding aid, it is an excellent choice for weld removal, blending and finish refinement on stainless steel and high nickel alloys.
3M™ Fibre Disc 787C contains the exact amount of 3M Precision Shaped Ceramic Grain (PSG) you need to optimize the balance of speed and longevity for challenging applications from grinding to deburring. Moreover, to keep the disc and workpiece cool, a grinding aid is incorporated, further prolonging disc life. Disc construction includes a stiff fiber backing and strong resin bond that provide durability and tear-resistance, which along with abrasive grain enables operators to complete more parts per disc and requires fewer disc changes. 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 and continuously self-sharpen as the points break off rather than gouging or 'plowing' as conventional abrasives do. To suit many different project needs, these discs are offered in a range of sizes and a variety of attachment styles. Larger sized discs have a 2.22 cm center hole and require the use of a 3M™ Disc Pad Face Plate and Hub, which are attached to a right angle grinder with a disc retainer nut (all sold separately). GL and TN quick change attachments are an option for 11.43 cm to 17.78 cm discs. Smaller sized quick change discs are also available (sold separately) and provide reliable attachment to the tool and easy disc changes between applications. Please select discs with the attachment design made for your system.
Fibre discs are heavy-duty abrasives that feature a tough, stiff backing made from vulcanized fibre 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 - 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.
