Abrasive Fiber Disc 3M 382887, 125 mm diameter, 22 mm hole

Abrasive Fiber Disc 3M 382887, 125 mm diameter, 22 mm hole is a durable grinding and surface-preparation disc designed for use with angle grinders and compatible disc sanders. The disc is intended for blending, finishing and removing rust, paint and weld scale from metal and other materials. Its fiber backing provides stable support for the abrasive layer, ensuring even material removal and predictable performance during workshop and maintenance tasks.

Advantages

The fiber construction delivers consistent abrasive contact and dimensional stability, reducing loading and vibration during operation. A medium-thickness profile balances aggressive stock removal with surface control, enabling controlled finishing without excessive gouging. The open-coat abrasive structure helps prevent clogging when working on painted or rusted surfaces, and the standard 125 mm size with a 22 mm center hole ensures compatibility with a wide range of angle grinders and disc sanders that use the same mounting.

Suitable for

• Removing rust and corrosion from metal surfaces
• Stripping paint and coatings prior to repainting
• Blending weld seams and smoothing weld scale
• General surface preparation before finishing or coating
• Workshop maintenance and fabrication touch-up

Key specifications

• Disc diameter: 125 mm
• Center hole diameter: 22 mm
• Backing type: fiber backing for dimensional stability
• Typical applications: rust, paint, weld scale removal, blending and finishing
• Intended mounting: compatible with angle grinders and disc sanders using 125 mm / 22 mm discs

How to use

Select the Abrasive Fiber Disc that matches the grinder or sander spindle and secure it according to the machine manufacturer’s instructions. Operate the tool at the recommended speed range for 125 mm abrasive discs and apply moderate pressure, allowing the abrasive to remove material without forcing the disc. Move the disc evenly across the workpiece to achieve uniform results and avoid staying in one spot to prevent gouging or overheating the substrate. Replace the disc when abrasive performance declines or the backing shows signs of damage.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, hearing protection and respiratory protection when generating dust or working on coated surfaces. Verify tool speed compatibility before mounting the disc and inspect the disc for damage prior to each use. Store discs flat in a dry area to maintain backing integrity and consistent performance.
