01｜Product Overview

3M’s 2nd-generation Precision-Shaped Grain combines the advanced mineral properties of original Cubitron and the pioneering microreplicated structure of 3M™ Trizact™ abrasives. The triangular grains fracture progressively under abrasion to form sharp cutting points and edges.Conventional ceramic abrasive grains are irregular lumps. Instead of clean slicing, they tend to plough through metal, trapping heat within workpiece and abrasive. This results in reduced cutting speed, shorter belt service life and defects such as excessive burn and scratches.
