The science behind 3M™ Precision-Shaped Grain
-
Our latest 3M Precision-Shaped GrainTransforming 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 Grain3M 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 AbrasiveConventional 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.

-
What makes 3M™ Cubitron™ 3 Precision-Shaped Grain technology different?
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.
-
Do 3M™ Cubitron™ 3 Abrasives run cooler during heavy grinding?
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.
-
What substrates can I use 3M™ Cubitron™ 3 Abrasives on?
They are suitable for a wide range of metals, including high‑strength and ultra high‑strength steel, aluminium alloys, titanium, carbon steel, and stainless steel.
-
How do 3M™ Cubitron™ II Abrasives help reduce rework in the paint booth?
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.
