Faster metal removal with 3M
- Rapid cut on stainless: You slice effortlessly through heavy weld seams using self-sharpening precision shaped ceramic grains that cut continuously fast.
- Cooler grinding prevents discoloration: The integrated grinding aid reduces operating friction temperatures so you can work heat-sensitive alloys without thermal damage.
- Tear-resistant vulcanized backing: Built with a stiff fiber foundation, it gives you dependable durability during high-pressure beveling and deburring tasks.
Tackle heavy weld seams and grind stainless steel efficiently with the 3m 787C fibre disc. Thanks to self-sharpening precision shaped ceramic grains with 36+ grit, you achieve a rapid cutting speed during demanding tasks such as beveling and deburring. The integrated grinding aid lowers friction temperatures, allowing you to work heat-sensitive alloys, titanium, and aluminium without thermal discoloration or damage to the workpiece. Its stiff vulcanized fibre backing and strong resin bond provide dependable tear resistance and stability under heavy grinding pressure. Mount this 125 mm disc via its 22.2 mm center hole onto your angle grinder using a matching backing pad up to 12000 RPM.

The 3M Fibre Disc 787C features our advanced 3M Precision Shaped Grain technology. These discs feature a rigid glass fibre backing and the strong resin adhesive for durability and tear resistance. The disc is constructed with a grinding additive and specially designed for ultra-fast cutting operations and low-pressure application.
The 3M Fibre Disc 787C offers much better performance than conventional fibre discs. Our fibre discs offer ultra-fast cutting action, making them an excellent choice for weld removal, blending and detailed finishing operations on stainless steels and alloys with high nickel content. The advanced solution for demanding applications Balance cost and performance and choose the abrasive with exactly the right lifetime and cutting power. 787C contains exactly the right amount of Precision Shaped Grain mineral (PSG) you need for an optimal balance between speed and life in all kinds of demanding applications, from grinding to deburring. A grinding aid (Grinding Aid) is added to keep the disc and workpiece cooler and extend the life of the disc. The disc consists of a stiff glass fibre backing and the strong resin adhesive for durability and tear resistance. With these features, combined with the abrasive grain, the user can work on more elements with one disc and the disc does not need to be replaced as often. The exceptional lifetime and cutting power of the 787C fibre disc make this one of 3M's best discs for intensive production environments. The performance of this product far exceeds that of conventional fibre discs. For tasks where more professional fibre discs probably cannot be used to their full potential, but where productivity is still key, these fibre discs deliver excellent throughput performance. Boost your production with 3M Precision Shaped Grain technology 3M Precision Shaped Grain is designed for improved output in light to intensive material removal, allowing users to complete tough tasks faster and with less effort. The disc wears evenly and because the abrasive remains cool and sharp, PSG products last significantly longer than their conventional counterparts and deliver long-term high performance in production applications. To achieve this high level of performance, engineers at 3M applied proprietary microreplication technologies to create very precise triangular structures from 3M Ceramic Abrasive Grain material. These structures were then electrostatically oriented and placed as sharp triangles on the back of the disc. These ultra-sharp dots cut through metal like a knife, instead of grooving or ploughing like conventional abrasives. As the disc wears down, the points break off and new sharp points are created. Tips for optimal use Fibre discs are suitable for intensive use and have a tough, rigid backing of vulcanised glass fibre that is wear-resistant, and stands up to tough grinding applications. For optimum performance, this disc should be used with a backing disc of the correct density for the respective application: a lighter backing disc for lighter cutting operations and a firmer disc for heavy-duty applications. Use of the correct backing pad ensures that the abrasive mineral remains sharp for maximum service life. Developed by 3M for top productivity 3M Abrasives engineers know all about the structure of abrasive minerals. 3M has been a top supplier of abrasives for the wood and metalworking industries for more than a hundred years, offering a comprehensive product range with high-quality solutions for all your tough metal grinding and sanding jobs. Fibre disc 787C is specially designed to take production to the next level by doing more work in less time. This is a great example of how 3M can use knowledge and science to provide advanced solutions that allow industry to operate faster, better and more efficiently.
