Walnut Shell Abrasive – Tumbling Grade (for deburring and polishing)
It helps clean and smooth parts while protecting sensitive surfaces.Thanks to uniform grains and low hardness, this organic tumbling media supports consistent results and reduces the risk of scratches.
It is suitable for both technical finishing and decorative polishing.
Tumbling abrasive grain sizes (walnut shell media)
0.2 – 0.4 mm – precision polishing of small components; ideal for delicate parts
0.3 – 0.5 mm – technical tumbling and surface smoothing for improved aesthetics
0.4 – 0.7 mm – more intensive finishing and cleaning of metal parts, helping reduce process time
Technical parameters – natural shell abrasive media
- Material: 100% natural walnut shell
- Hardness: approx. 3.0–3.5 Mohs
- Grain shape: irregular, fine-grained
- Bulk density: 0.6–0.8 g/cm³
