Flap discs use precision-shaped grain technology

3M Abrasive Systems has introduced 3M™ Cubitron™ II flap discs for weld grinding, deburring, rust removal, edge grinding, and weld seam blending.

The discs use the company’s proprietary precision-shaped grain technology. The uniformly sized triangular grains are evenly distributed onto the backing, allowing them to slice through the substrate. They continuously fracture during use to form sharp points and edges. This technology requires less pressure from the operator to help reduce fatigue.

The backing enables controlled, even wear, allowing full use of the disc with no premature dulling or glazing. The discs work in low-, medium-, and high-pressure applications. A grinding aid helps keep the product cool while grinding on stainless steel and heat-sensitive metals.
