Our unique Aka-Rhaco is a thin steel disc with a soft polymer coating to hold grinding paper. It lasts for up to 1000 applications and is optimised to be used with Rhaco Grit grinding paper. This means that it can easily substitute expensive PSA or foil backed grinding papers. Therefore, Rhaco Grit and Aka-Rhaco are very cost-effective solutions when using grinding paper in your sample preparation.
Aka-Rhaco is available in three different versions. Aka-Rhaco, a thin steel disc for use on magnetic support discs; Aka-Rhaco Flex, a soft polymer disc containing ferrous particles for use on magnetic support discs and Aka-Rhaco PSA, a self-adhesive foil to be glued directly on an aluminium support disc.
As an additional benefit, Aka-Rhaco can also be used with self-adhesive polishing cloths. Simply leave the liner on the polishing cloth and attach the cloth to an Aka-Rhaco disc. When the cloth is worn, it can easily be changed. This makes it a cost-effective and more sustainable solution due to saving the cost of buying magnetic polishing cloths and having to dispose of a steel disc for every polishing cloth.

What makes Aka-Rhaco unique?
The polymer surface of Aka-Rhaco has a very strong adhesion compared to other available adapter discs. This allows for the use of plain backed grinding papers instead of foil backed grinding papers, resulting in a more cost efficient solution. Even though the adhesion is very strong, it is not a glue that is used and that again makes it easy to exchange grinding papers and also provides a very long lifetime.
How do I use Aka-Rhaco with grinding paper?
After the Aka-Rhaco has been placed on a magnetic support disc, the liner on top is removed and a grinding paper is attached to the sticky surface. When the paper is worn or has to be replaced with another # size it is simply pulled off and a new paper is attached. For storage, you can either leave the grinding paper on the Aka-Rhaco or put the liner back on. When the adhesion is reduced, the Aka-Rhaco can be cleaned using liquid soap and lukewarm water. After spin-drying the disc it is almost like new again.
