The science behind 3M™ Precision-Shaped Grain

Our latest 3M Precision-Shaped Grain

Transforming the industry, our cutting-edge 3M Precision-Shaped Grain, with proprietary breakthroughs in grain shape and molecular bonding, helps increase productivity, safety and sustainability.
Original 3M Precision-Shaped Grain

3M pioneered the first precision-shaped grain using 3M microreplication technology to form consistent sharp peaks that easily “slice” through metal—cutting cooler, faster, and lasting longer than conventional abrasive grain.
Conventional Ceramic Abrasive Grain

Conventional ceramic abrasive grain tends to “plow” through metal, causing heat to build up in the workpiece and abrasive, resulting in a slower cut and shorter abrasive life compared to our latest precision-shaped grain.
