How to achieve the best finish

Let the diamonds work: apply steady, moderate pressure to avoid overheating.
Step through the grits: avoid big jumps (e.g., 60 → 100 → 200 → 400 → 800 → 1500 → 3000).
Dry vs wet: when possible, work wet to reduce dust and stray scratches; always check the blade/disc specs.
Use the right pads & supports: suitable hook-and-loop backing pads and correct clamping on the grinder.
Cleanliness & extraction: reduce loading on discs and extend service life.
