Buying Guide: Key Considerations For Angle Grinder Sanding Attachments
- Compatibility: Check thread type (5/8-11 is common) and arbor size to fit your grinder. Some kits include adapters to fit drills as well.
- Grit Range: For wood, start coarse (40-80) and progress to finer grits (120-600). For metal, use higher grit for finishing, but plan for aggressive removal with coarser options.
- Backing Pad Quality: A reinforced pad reduces vibration and increases durability. Look for soft sponge layers for uneven surfaces.
- Disc Material: Aluminum oxide is versatile; zirconia and ceramic discs excel for metal and heavy stock removal but may wear faster on wood.
- Application Versatility: Some kits include drill adapters, turning your drill into a sander. This can be useful for detailed work but verify RPM limits.
- Safety: Use appropriate PPE, avoid overheating the workpiece, and follow tool manufacturers’ speed ratings to prevent disc breakage.
