The 3M Cubitron 3 Roughing Disc is an extremely fast cutting and durable, rigidly bonded disc for removing welds and other heavy duty sanding applications. It has a recessed centre point that allows grinding at any angle and is suitable for use on almost all materials, with a special formulation for stainless steel, mild steel and aviation alloys. For the 3M Cubitron 3 grinding disc, the revised 3M precision-moulded grain is used, in which patent-protected micro-fragments of molecular binding technology are used. Their structure is created so that they break continuously during the grinding process and always form many sharp cutting edges. These smooth, sharp edges help create an abrasive that cuts faster, grinds cooler, and lasts much longer than traditional abrasives. 3M Cubitron high performance abrasives are designed for professionals who demand more from their equipment. Choose the 3M Cubitron 3 grinding disc to experience the next generation of grinding performance.
