3M 460683 Cubitron™ II Disco de fibra 115 mm x 22 mm P36 pack de 25

Metal fabricators and welders reach for the 3M 460683 Cubitron™ II fibre disc when heavy stock removal, weld grinding, and edge chamfering demand both speed and endurance. The 115 mm diameter and 22 mm bore fit standard angle grinders, while the P36 grit and precision-shaped ceramic grain cut aggressively through stainless steel, mild steel, and aerospace alloys.
