Sanding backings Heidmann 125 mm for random orbital sander — replacement backing pad

Replacement backing pad for random orbital (eccentric) sanders by Heidmann, 125 mm diameter. This backing pad is designed to hold hook-and-loop sanding discs securely and provide an even, stable surface for sanding tasks. It is intended for use on wood, painted and varnished surfaces, and similar materials where controlled material removal and surface smoothing are required.

Advantages

The 125 mm backing pad offers consistent disc retention and balanced rotation for uniform sanding results. Its construction provides reliable support to abrasive discs, helping to reduce chatter and uneven wear. Compatible with common random orbital sanders that accept 125 mm pads, it simplifies disc changes through hook-and-loop attachment and supports a range of sanding grits for different stages of surface preparation and finishing.

Suitable for

• Removing paint, varnish and surface coatings
• Sanding and smoothing wooden surfaces
• Surface preparation before painting or finishing
• Light material removal and blending of repaired areas

Key specifications

• Diameter: 125 mm
• Attachment system: hook-and-loop (Velcro) for abrasive discs
• Compatibility: for use with random orbital (eccentric) sanders accepting 125 mm pads
• Purpose: backing and support for sanding discs during finishing and preparation

How to use

Ensure the sander is disconnected from power before fitting the backing pad. Align the pad with the sander's drive plate and press firmly until it is securely seated. Attach the appropriate hook-and-loop sanding disc by pressing it onto the pad with even pressure. Operate the sander according to the tool manufacturer's instructions, using steady, controlled passes and appropriate sanding grits for the material and task. Replace the backing pad if it becomes worn, cracked or no longer holds discs securely.

Usage recommendations

Use progressively finer grits to achieve smooth finishes; start with coarser grits for material removal and move to finer grits for final smoothing. Inspect the backing pad regularly for wear and keep the hook-and-loop surfaces clean from dust and debris to maintain secure disc attachment.
