Coarse ≈ 40–60 grit scratch, Medium ≈ 80–120, Very Fine ≈ 150–180, Ultrafine ≈ 220. Equivalents are guidelines — non-woven material isn’t officially grit-rated. Full guide below.
What surface conditioning belts actually do
Non-woven belts are fibrous instead of coated — so they clean, blend, deburr and finish steel, stainless and aluminum without the loading and heat build-up of a regular sanding belt. That’s why they last long and leave consistent, uniform finishes in fewer steps.
They’re the belt for erasing imperfections, blending scratch patterns into a satin look, and prepping surfaces — on stainless, aluminum, titanium, fiberglass, plastics and nonferrous alloys.
Grade guide
Four grades, four colors
Grit equivalents are practical guidelines from our and our customers’ experience — non-woven material is not officially grit-rated.
Approx. 40–60 grit scratch pattern. Removes real material — use a lighter hand.
Approx. 80–120 grit scratch pattern. The all-round cleanup and blending grade.
Approx. 150–180 grit scratch pattern. Pre-finish blending.
Approx. 220 grit finish. The final satin step.
The full sequence: Coarse, Medium, Very Fine, Ultrafine.
Suitability
What are these belts best for?
Use these belts for
- Blending and uniform satin finishes on blades and parts
- Deburring edges and cleaning up welds
- Removing surface imperfections without changing geometry
- Stainless, aluminum, titanium, fiberglass, plastics
Not the right belt for
- Stock removal or shaping — use ceramic Shredder belts
- Precise grit-spec finishing — equivalents are approximate
- Stropping — use the Leather Belt
Getting a clean, even finish
1. Use light to moderate pressure — the fiber does the work. Go lighter still on Coarse, which can remove significant material.
2. Follow the sequence: Coarse → Medium → Very Fine → Ultrafine.
3. Keep the work moving to avoid dwell marks and keep the finish uniform.
4. These belts run long — reduced loading means far more working time than a coated belt of similar cost.
Technical details
The deeper dive
The fibrous web resists loading and heat build-up, so the belt keeps cutting consistently instead of glazing — longer working life and repeatable finishes.
A reinforced scrim backing keeps the belt stable, while the material can still shape and form for detail and edge work.

Questions
Surface conditioning FAQs
What grit are these belts?
Non-woven material isn’t officially grit-rated. As practical guidelines: Coarse ≈ 40–60, Medium ≈ 80–120, Very Fine ≈ 150–180, Ultrafine ≈ 220 grit scratch patterns.
Which grade should I start with?
For general cleanup and blending, start Medium. Coarse only when you need real bite — and use a light hand.
Will they fit my grinder?
Standard 2″ x 72″ — fits the same machines as every belt in this family.
What materials do they work on?
Stainless steel, steel, aluminum, titanium, fiberglass, plastics and nonferrous alloys.
Is the kit worth it?
The kit is one belt of each grade — the full Coarse-to-Ultrafine sequence for a uniform finish in fewer steps.
When do I replace one?
When the fiber stops cutting and finishes go inconsistent — though reduced loading means these run notably longer than coated belts.
