This Neutral Window Grinder 4-part anodised without logo with fine screen is CNC-machined and made of anodised aluminium with precision made diamond-shaped teeth. They come with a magnet to keep the lid safely attached and a nylon friction ring which ensures abrasion-free grinding.
The process of anodising changes the metal surface of the aluminium into a robust protective coating whereby the natural coating thickens up to 0,03mm. The surface is ca. 8 times harder then raw aluminium, protects against mechanical influences and is weather- and corrosion-resistant.
