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.
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 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.

3M™ Cubitron™ 3 Abrasives use a re‑engineered precision-shaped grain designed to continuously fracture into sharp cutting points. This “slicing” action provides faster cutting, increased durability, and cooler operation compared to conventional abrasives.
Yes, they are designed to run cooler. The precision-shaped grain reduces friction and heat buildup, helping protect heat‑sensitive metals and maintaining abrasive performance during demanding cutting and grinding applications.
They are suitable for a wide range of metals, including high‑strength and ultra high‑strength steel, aluminum alloys, titanium, carbon steel, and stainless steel.
3M™ Cubitron™ 3 Fibre Discs provide a fast initial bite and maintain cutting speed on tough welds, helping technicians move through the heavy grinding stage more efficiently with fewer disc changeouts.
3M™ Cubitron™ II Precision‑Shaped Grain creates a more consistent, uniform finish compared to conventional abrasives, reducing scratch patterns that lead to dieback, rework, or visible defects after painting.
