Abrasive Fiber Disc 3M Cubitron 460685 Ø125 mm, 22 mm centre hole

Abrasive Fiber Disc 3M Cubitron 460685 Ø125 mm, 22 mm centre hole is a mineral-graded fiber disc engineered for efficient material removal and surface preparation on metal and other hard surfaces. The disc measures 125 mm in diameter and features a 22 mm centre hole to fit angle grinders and compatible backing pads. Built using 3M Cubitron abrasive technology, it is intended for consistent cutting, blending and finishing tasks in workshop and industrial environments.

Advantages

The 3M Cubitron abrasive construction offers high cut rate and long life compared with conventional abrasives, reducing the need for frequent disc changes. The fiber backing provides rigidity for controlled stock removal while maintaining stability under pressure. The 22 mm centre hole allows direct mounting on many angle grinders and backing plates, simplifying setup. Designed for metalworking, the disc maintains consistent performance for a range of surface-preparation operations.

Suitable for

• Heavy-duty material removal on steel and stainless steel
• Surface preparation prior to welding or coating
• Blending weld seams and smoothing rough edges
• General workshop grinding and finishing on hard substrates

Key specifications

• Diameter: 125 mm
• Centre hole: 22 mm
• Backing: fiber disc for rigidity and durability
• Abrasive type: 3M Cubitron mineral technology for fast cutting
• Intended use: material removal, blending, surface preparation on metal and hard surfaces
• Compatible tools: angle grinders and backing pads that accept a 22 mm centre hole

How to use

Mount the disc securely on an angle grinder or backing pad that accepts a 22 mm centre hole, following the tool manufacturer’s mounting instructions. Use appropriate rotational speed within the grinder’s recommended range and apply steady, even pressure while grinding; avoid excessive force that could reduce disc life or damage the workpiece. Maintain proper contact angle for the task—flatter for surface preparation and slightly angled for aggressive material removal. Replace the disc when abrasive effectiveness diminishes or the backing shows significant wear.

Usage recommendations

Use appropriate personal protective equipment including eye and face protection, hearing protection and gloves. Ensure the grinder’s guard is in place and follow workplace safety procedures. For best results on metal, use consistent traversing motions and allow the abrasive to do the cutting rather than pressing excessively. Store discs flat in a dry environment to preserve performance.
