Disco de desbaste de fibra 3M Cubitron II 987 C 125 mm K60+ INOX grão cerâmico

Abrasive Fiber Disc 3M Cubitron II 987 C 125 mm K60+ INOX Ceramic Grain is a high-performance abrasive disc engineered for metalworking tasks, especially stainless steel surface preparation, deburring and blending. The disc features 3M Cubitron II ceramic grain, designed to provide a fast cut rate and extended life compared with conventional abrasive products. Its 125 mm diameter suits common angle grinders and power sanders, delivering efficient material removal while maintaining a consistent finish on ferrous and stainless alloys.

Advantages

The Cubitron II ceramic grain structure promotes faster material removal and reduced loading, resulting in longer usable life and fewer disc changes during a job. The fiber backing offers stable support for aggressive cutting while resisting tearing and heat build-up. The K60+ grit balances stock removal and surface refinement, enabling both rapid grinding and acceptable final appearance. Overall, the product reduces downtime and abrasive consumption in professional metal fabrication and maintenance environments.

Suitable for

• Stainless steel surface preparation and cleaning
• Deburring welded joints and edges
• Blending surface imperfections and weld seams
• General metal grinding and stock removal on steel and alloys
• Use with 125 mm angle grinders and compatible power sanders

Key specifications

• Diameter: 125 mm
• Grit: K60+ (medium coarse)
• Abrasive type: INOX ceramic grain (Cubitron II)
• Backing: fiber disc for stable support
• Intended use: metalworking, stainless steel, deburring, blending

How to use

Mount the abrasive fiber disc on a suitable 125 mm angle grinder or power sander following the tool manufacturer’s mounting instructions and safety guidelines. Start with light contact to establish the cutting action, then apply consistent pressure and maintain an appropriate grinding angle to avoid overheating. Move the disc steadily across the workpiece to achieve even material removal; avoid prolonged stationary contact in one spot. Replace the disc when cutting performance or surface finish noticeably declines.

Recommendations

Use appropriate personal protective equipment including eye, face and hand protection, and respiratory protection when generating dust. Select a compatible rotational speed within the disc and tool specifications. For best results on stainless steel, use controlled pressure and cooling intervals to minimize discoloration; allow the workpiece to cool between passes if necessary. Store discs in a dry, stable environment away from extreme temperatures.
