2. Setup and Installation
These sanding discs are designed for quick and easy attachment to compatible sanding tools. Ensure your tool is unplugged or its battery removed before installation.
2.1 Compatibility
- Compatible Devices: Orbital Sanders and Angle Grinders with a Velcro backing pad.
- Disc Diameter: 150mm.
- Hole Pattern: 6-hole for efficient dust extraction.
2.2 Installation Steps
- Prepare the Tool: Ensure your orbital sander or angle grinder is turned off and disconnected from its power source.
- Inspect Backing Pad: Check the Velcro backing pad on your tool for cleanliness and ensure it is free from debris or old abrasive residue. A clean pad ensures optimal adhesion.
- Align the Disc: Carefully align the 6 holes on the Bosch sanding disc with the corresponding holes on the tool's backing pad. This alignment is crucial for effective dust extraction during operation.
- Attach the Disc: Press the sanding disc firmly onto the backing pad. The Velcro (hook and loop) system will secure the disc in place. Ensure it is centered and flat against the pad.

3.1 Recommended Applications
- Wood Sanding: Effective on softwood, hardwood, resinous wood, chipboard, and MDF.
- Paint and Coating Removal: Suitable for sanding coatings like varnish, fillers, roughcast, and composites.
- Deburring: Removing burrs or sharp edges from materials.
- Discoloration Removal: Addressing surface discoloration.
- Structuring and Final Sanding: Preparing surfaces for subsequent steps or achieving a specific texture.
- Light Weld Removal: Specifically for spot welds on mild steel.
3.2 Usage Tips
- Even Pressure: Apply consistent, light pressure across the sanding surface to ensure uniform material removal and prevent gouging.
- Movement: Move the sander in overlapping passes to avoid swirl marks and achieve a smooth finish.
- Dust Extraction: Utilize the dust extraction capabilities of your sander. The 6-hole pattern on the disc is designed to work with these systems for a cleaner workspace and extended disc life.

4. Maintenance and Storage
Proper maintenance and storage will help preserve the quality and effectiveness of your Bosch Professional sanding discs.
4.1 Maintenance
- Cleaning: While in use, discs may become clogged with sanding dust. For minor clogging, a sanding disc cleaning stick or a stiff brush can sometimes extend the disc's life. However, heavily clogged discs should be replaced.
- Inspection: Before each use, inspect the disc for any tears, excessive wear, or damage to the Velcro backing. Do not use damaged discs.
4.2 Storage
- Dry Environment: Store sanding discs in a cool, dry place to prevent moisture absorption, which can degrade the abrasive and backing.
- Flat Storage: Store discs flat to prevent warping or bending, which can affect performance and lead to uneven sanding.
- Original Packaging: Keep unused discs in their original packaging to protect them from dust and environmental factors.
5. Troubleshooting
This section addresses common issues encountered during the use of sanding discs.
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor sanding performance / Slow material removal | Disc is worn out or clogged with material. Incorrect grit for the task. Insufficient pressure. | Replace the sanding disc. Use a coarser grit if more aggressive removal is needed. Apply consistent, light pressure. |
