Available in fibre discs, flap discs, bonded wheels, belts and sanding discs, no one matches the breadth of the 3M Precision-Shaped Grain product offering. From coarse grade grinding through ultra-fine grade sanding, there’s a family of 3M products to bring your shop to the next level.

The speed is in the science.

For almost a century there was only one option in abrasive technology: crushed abrasive grains that plow through metal, heat up, turn dull and stop cutting. 3M engineers knew there was a better way. That’s why they invented 3M Precision-Shaped Grain — a triangular ceramic grain that slices through the substrate and continually fractures into new sharp cutting edges.
