Narrow belts are widely used across metalworking, woodworking, and fabrication. Use the sections below to jump to your substrate, then paste your table back into the dashed area to show common sizes with pre-filled grit links to the calculator.
How to Use This Page
- Pick a substrate (Aluminium Oxide, Zirconia, Ceramic, etc.).
- Scan the quick tips for best-use cases and grit/grade progression.
- Table area: replace the “PUT … TABLE HERE” row with your full table rows.
Aluminium Oxide Narrow Belts
The dependable all-rounder for wood, non-ferrous metals and general shop work. Good value, consistent finish, wide grit coverage.
Best for: soft & hard woods, aluminium/brass clean-ups, edge breaking, pre-finish passes.
Grit ladder: 60 → 80 → 120 → 150/180 (refine as needed). Start at 36–40 only for heavier removal.
Tip: Let the belt cut. Excess pressure shortens life and worsens finish.

Zirconia Narrow Belts
Cooler, longer grinding on steels and tougher materials. Ideal for heavier stock removal with portable sanders and linishers.
Best for: carbon/stainless steels, hard woods where loading/heat are issues.
Grit ladder: 36/40 → 60 → 80/100 (120 for finishing, else switch to AO).
Tip: Keep pressure moderate; let the self-sharpening grain refresh during the cut.
Zirconia — Common Sizes & Grit Links
| Belt Size | Grit 24/36 | Grit 40 | Grit 60 | Grit 80 | Grit 100 | Grit 120 |

Ceramic Narrow Belts
Maximum cut on hard alloys and aggressive grinding. Use when removal rate matters more than cosmetic finish.
Best for: stainless, hard alloys, weld removal, edge shaping.
Grit ladder: 36/40 → 60 → 80 (switch to AO for finer finishing).
Tip: Maintain belt tracking and wheel condition — glazed edges kill ceramic performance.

| Belt Size | Grit 36 | Grit 40 | Grit 60 | Grit 80 | Grit 100 | Grit 120 |

Silicon Carbide Narrow Belts
Sharp, friable grain for brittle or loaded materials and ultra-fine finishing.
Best for: glass, stone, composites, paints/lacquers, non-ferrous with loading risk.
Grit ladder: 80 → 120 → 240 → 400 → 600 (extend to 800/1000 where available).
Tip: Use light pressure and keep cool—SiC cuts fast but can fracture under heavy load.

SCM / Non-Woven Narrow Belts
Conformable surface conditioning for de-burr, blend, clean, and satin finish.
Best for: blending grain, removing light scratches/oxidation, final satin on metals.
Grade ladder: CRS → MED → FIN → UFN (Coarse → Medium → Fine → Ultra Fine).
Tip: Lower pressure, higher surface contact. Great on contact wheels and slack belt.

Trizact Narrow Belts
Structured abrasives for predictable, step-down finishing and tight Ra control.
Best for: stainless finishing, turbine/medical, precision steps before polishing.
Grade ladder (example): A160 → A100 → A65 → A45 → A30 → A16 (adjust per spec).
Tip: Maintain consistent SFPM and pressure to get full benefit from the micro-replicated grain.

Agglomerate Narrow Belts
Clustered grain for very long life, uniform wear, and consistent finish on large runs.
Best for: steels and non-ferrous where consistency beats peak cut rate.
Selection: Choose the final finish you need—agglomerates maintain cut as they wear.
Tip: Great for automated or repeat passes—expect fewer belt changes.

Felt Narrow Belts
Non-abrasive belt for compound-assisted polishing and mirror finishing.
Best for: final polish on stainless, brass, aluminium (with polishing bars/compounds).
Usage: No grit scale—pair with the correct compound (cut, color, mirror) per material.
Tip: Keep surfaces clean between compounds to avoid dragging coarse residue forward.
