The Science of 3M™ Precision-Shaped Grain: Increases Productivity & Lowers Overall Grinding Costs

3M™ Re-Engineered
Precision-Shaped Grain

Uses 3M microreplication technology to form 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 the metal, causing heat to build up in the workpiece and the abrasive – resulting in a slower cut and shorter abrasive life.
