## Specifications

| Spec | Value |
|---|---|
| Coating thickness | No coating — deburrs and radiuses edges by ~0.05 mm while removing only microns from flat faces; leaves a uniform satin sheen. |
| Tolerance impact | Minimal on faces (microns), but every edge and corner picks up a ~0.05 mm radius — that is the point of the process. Flag any edge that must stay sharp; parts tumble loose together, so delicate features can pick up contact marks (compartmented media available). |
| Corrosion rating | Unchanged — no coating is added; removing burrs and smearing slightly improves cleanability but corrosion behavior remains that of the base material. |
| Appearance | Uniform low-gloss satin with softened edges; less refined than bead blasting but consistent across the whole batch. |
| Applicable substrates | aluminum, stainless-steel, steel, copper-alloys, plastics |

## Not suitable for

Large parts above ~300 mm (they exceed bowl capacity and batter the media — deburr by hand instead); sealing edges and O-ring lands that cannot tolerate the ~0.05 mm edge radius; cosmetic show faces that must stay free of random contact marks; threads finer than M3, which media can peen.

## Typical applications

- Batch deburring of small machined parts
- Hardware and fittings needing safe-to-handle edges
- Pre-plating surface uniformity at volume
- Edge-break callouts (e.g. 0.1 mm max burr) across hundreds of parts
