Mirka Galaxy is a new kind of high technology abrasive. It combines effectiveness with long use life, thanks to a new kind of self-sharpening ceramic grain, a clogging resistant coating and the new Multifit hole configuration.
The ceramic grains used in the Mirka Galaxy are self-sharpening. This means every time an edge of an abrasive grain breaks off, a new cutting edge is simply formed, making it possible for the Galaxy to continue cutting longer and longer. The ceramic grains of the Galaxy are engineered not to dull, as once the edge of the abrasive grain breaks off it simply forms new edges, making it possible for the Galaxy to continue cutting – from edge to edge. The self-sharpening ceramic grains allow for a winning combination of long life, fast cut and easy polishability.
Thanks to the optimized Multifit hole configuration, the abrasive is always correctly placed on any machine without the need to specifically align it. At its core, the Mirka Galaxy is a multi purpose product, suitable for the sanding of both soft and hard materials as well as various substrates.
Superb edge wear resistance, excellent clogging resistance, dust repellent coating, and optimal dust extraction - the Mirka Galaxy serve well in the automotive sector, in vehicle manufacturing, collision repair, marine production as well as in the wood sector.

Mirka Galaxy Sanding Discs - 125mm/5" features a hook and loop back making it easy to attach to your sander.

Michael Finnerty
Wood finishing with Mirka

I was impressed on two counts with Galaxy discs. Firstly, the finish on lacquer with 1200 grit was excellent and I only went up to 2000 see if any real difference was apparent and it was. This resulted in a minimal cut and polish to get a great result.
Secondly, these discs certainly last longer than any other product I have used.
