3M Cubitron II Fibre Disc Grit

The 3M Cubitron II Fibre Disc is a precision-shaped ceramic abrasive grinding disc (also called a fibre disc or resin fibre sanding disc) built for fast, aggressive stock removal on metal. It is made for use on angle grinders and similar backing-pad setups in fabrication, welding prep, and metal finishing work.

Key Features:

• Precision-shaped ceramic grain: Triangular grain shapes fracture as they wear. This keeps fresh, sharp cutting edges exposed.
• Fast cut and long life: The grain is designed to cut faster and last longer than conventional abrasive fibre discs.
• Cooler grinding: Sharp, continuous cutting helps reduce heat. This helps limit heat discoloration and warping on the workpiece.
• Durable fibre backing: A rigid resin fibre backing gives stable support for aggressive grinding.
• Versatile metal use: Suited to steel, stainless steel, and other alloys. Common jobs include weld blending, deburring, beveling, and surface preparation.
• Multiple grits available: Choose coarser grits for heavy stock removal or finer grits for blending and finishing.

Backed by 3M's long-standing abrasives expertise, the Cubitron II Fibre Disc line helps shops and fabricators cut faster, change discs less often, and get consistent results across a wide range of metalworking applications.
