Buying Guide: Key Purchase Considerations
- Grinder compatibility: Verify arbor size (commonly 7/8″ or 5/8″) and disc diameter to ensure a secure fit on your grinder.
- Material and finish: Wool discs are ideal for delicate polishing and rust removal, while felt and flap-backed discs can help achieve mirror finishes on metal surfaces.
- Backing and durability: Backing plates (fiberglass or plastic) influence stability at high RPMs and long-term durability.
- RPM guidance: Use compatible speeds within the recommended RPM range to prevent disc disintegration or surface damage.
- Surface compatibility: Some discs are not suited for car paint; use appropriate discs for paint and primed surfaces to avoid burns.
- Set variety: Multi-pack options provide a range of grits and finishes, enabling a single purchase to cover initial rust removal through final buffing.
