Buying Guide

- Grit range and application: Coarse grits remove material quickly; medium and fine grits finish and polish. For flat metal panels, start coarse and move to finer grits.
- Construction and backing: Non-woven fibers, resin bonding, and open-cell design influence heat management, clogging, and finish quality.
- Quick-change systems: If you swap grits frequently, a quick-change holder reduces downtime and improves throughput.
- Ventilation and safety: Wear eye protection and a mask; consider disc material release heat and sparks depending on workpiece.
