3M™ Roloc™ Fibre Disc 787C, 120+, TR, 4 in, Die R400BB, 25/Carton, 100 ea/Case

The Advanced Solution for Challenging Applications

Balance cost and output by selecting the abrasive with precisely the right amount of cut and life, no more and no less. 3M™ Roloc™ Fibre Disc 787C contains the exact amount of precision shaped 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 premier abrasive grain enables operators to complete more parts per disc and requires fewer disc changes.

The exceptional life and cut of the 787C Fibre Disc make it one of 3M's best grinding discs for high production environments, providing significant gains over conventional fiber discs. When a highest-tier fiber disc may be under-utilized but productivity is still your bottom line, the 787C Fibre Disc delivers outstanding throughput. This fiber disc is an excellent choice for a range of applications such as:

Edge chamfering Beveling Deburring

Weld removal

Step Up Production with 3M Precision Shaped Grain

Developed for improved output on light to heavy stock removal, 3M Precision Shaped Grain lets operators finish tough tasks faster and with less fatigue. It wears evenly, and because the abrasive itself stays cooler and sharper, 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-sharpen as the points break off.

Roloc™ System Enables Easy Tool Attachment

To suit many different project needs, this disc is offered in a range of sizes and a variety of attachment styles. The 3M™ Roloc™ Fibre Disc 787C is available in 2-4" diameters for use with the following Roloc attachment systems: TSM and TR. Please select discs with the attachment design made for your system. 3M™ Fibre Disc 787C is also available in larger sizes with a center hole or GL and TN attachments (sold separately).

Tips for Optimal Use

Fiber 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 3M™ Roloc™ Disc Pad of the appropriate density for the application—a softer disc pad for lighter weight grinding applications, and a harder density disc pad for more heavyweight grinding applications. Using the correct pad for the application ensures that the abrasive mineral will re-sharpen, maximizing the life of the abrasive.
