Coarse ≈ 40–60 grit scratch, Medium ≈ 80–120, Very Fine ≈ 150–180, Ultrafine ≈ 220. Guidelines — non-woven is not officially grit-rated.
The satin step for 1x42 machines
Fibrous non-woven belts blend scratch patterns into uniform satin finishes — and because the web resists loading and heat, they outlast coated belts many times over. Same material as our 2x72 conditioning line, sized for 1″ x 42″.
