Fibre Discs from 3M: Grinding at the speed of science.
-
While metal grinding can be performed with a flap disc, depressed center grinding wheel or an abrasive belt, the fastest way to grind is with a fibre disc. These coated abrasive discs allow you to grind with less pressure than other angle grinder products while delivering significantly higher material removal rates. While product life will be shorter than a flap disc or a grinding wheel, fibre discs remove more metal faster — delivering time savings and productivity gains. Fibre discs also produce a finer finish than depressed center grinding wheels, which can help reduce steps in your overall finishing process.
3M offers a range of fibre disc options to help bring your metal shop to the next level. Our legendary 3M Precision-Shaped Grain powers many of our industry-leading fibre disc products — including premium 3M™ Cubitron™ II Fibre Discs. The triangular ceramic grain continuously fractures to form new sharp edges throughout the life of the disc, allowing them to cut cooler, faster and longer than competitive fibre disc products. This same technology is featured in our budget-friendly Advanced Series fibre discs.

The Science of Speed
When you need speed and efficiency, reach for a fibre disc. Here’s why: fibre discs are made of a single layer of precisely oriented abrasive grains on a stiff vulcanized fibre backing. The entire face of the disc is covered in grains, increasing the cutting surface area. This allows the cutting teeth to “bite” into the metal and remove material more quickly than a depressed center grinding wheel.
Using the proper disc backup pad enhances grinding performance even further. For example, using a firm backup pad with a coarse grain disc allows for optimal mineral breakdown for ideal disc performance.
3M Fibre Disc Product Tiers
-
Every metal shop is unique. That’s why 3M offers distinct abrasive product tiers to help you get the right fibre disc to fit your application needs and budget. Premium 3M™ Cubitron™ II Fibre Discs provide the fastest cut and longest life, making them an ideal choice for heavy volume production applications.
If you’re looking for a fast cut at a value price, or don’t need the extreme long life of 3M™ Cubitron™ II Abrasives, our Advanced Series Fibre Discs are an ideal alternative that outlast conventional ceramic discs.
