Pack of 10 – 3M Cubitron II 784F 13 x 330mm Ceramic Sanding Belts | 36+, 60+, 80+ & 120+ Grit
The 3M Cubitron II 784F 13 x 330mm Ceramic Sanding Belts – Pack of 10 are premium-performance abrasive belts engineered for fast cutting, long service life and demanding metalworking applications.
Featuring 3M Precision-Shaped Grain technology, Cubitron II abrasive continuously fractures into sharp cutting points that slice through metal rather than simply ploughing or scratching the surface. This helps the belt cut faster, run cooler and maintain effective cutting performance for longer than many conventional abrasive belts.
The compact 13mm x 330mm belt size is ideal for compatible file sanders, power files and narrow belt sanders, providing excellent access to tight spaces, corners, edges, welds and difficult-to-reach areas.
These belts are particularly suited to stainless steel fabrication, weld removal, edge grinding, deburring, blending and surface preparation.
A built-in grinding aid helps reduce heat generation during grinding, making 3M Cubitron II 784F particularly suitable for stainless steel and other heat-sensitive metals.
Supplied in a convenient pack of 10 belts per selected grit.
