Abrasive Fiber Disc 125x22 mm K80 3M Cubitron 787C – pack of 25

Abrasive Fiber Disc 125x22 mm K80 3M Cubitron 787C – pack of 25 are fiber-backed grinding discs with ceramic abrasive grain engineered for metalworking. The 125 mm diameter and 22 mm centre hole make them compatible with standard 125 mm angle grinders. The Cubitron 787C formulation delivers high cut rate and extended life during surface grinding and finishing of steels, stainless steel (inox) and other ferrous metals. Supplied as a pack of 25, these discs are intended for professional fabrication, maintenance and repair tasks where consistent performance and downtime reduction are required.

Advantages

The Cubitron ceramic grain structure provides faster material removal compared to conventional abrasives while maintaining a steady cut rate across the disc life. The fiber backing offers stiffness and dimensional stability for aggressive grinding applications, and the bonding system resists loading when working with stainless steel. Available in grit K80, these discs balance stock removal and surface finish for common metal preparation and blending operations.

Suitable for (tasks / use cases)

• Surface grinding and stock removal on carbon steel
• Finishing, blending and deburring of stainless steel (inox)
• Weld seam removal and preparation prior to painting or coating
• Metal fabrication, maintenance and workshop use with 125 mm angle grinders
• General-purpose metalworking where K80 grit provides medium-coarse cut

Key specifications

• Disc diameter: 125 mm
• Arbor/centre hole: 22 mm
• Abrasive grain: Ceramic (Cubitron) for efficient cut
• Grit size: K80 (medium-coarse)
• Backing: Fibre (fiber) for rigidity and durability
• Pack quantity: 25 discs

How to use

Mount the disc securely on a compatible 125 mm angle grinder with a 22 mm centre arbor following the tool manufacturer’s instructions. Use appropriate guard, backing flange and tightening methods to ensure safe installation. Operate the grinder at the recommended speed range for the disc and apply steady, even pressure; avoid excessive force that can accelerate wear or cause disc damage. Allow the abrasive to perform the cutting action, moving the grinder along the workpiece in overlapping passes until the desired material removal or finish is achieved.

Usage recommendations

Always wear appropriate personal protective equipment: eye protection, hearing protection, gloves and respiratory protection if airborne dust is present. Ensure the workpiece is securely clamped and check the disc for damage before each use. For stainless steel, use light, consistent pressure to reduce heat build-up and minimize surface discoloration. Replace discs when worn, torn or if the bond fails to maintain consistent cutting performance.
