I have tried many brands over the years. Galaxy paper is the best for performance and value. The range of grits means I can chase any smoothness level I need. I use Galaxy paper in support of the hand plane work that I do.
I am a very amateur hobby woodworker, and purchased the galaxy sanding discs based on their appearance - I thought they were mesh discs, when very clearly, by both their description AND their price point, they weren't. They do last longer than the traditional sandpaper discs, but I have become very used to using the mesh discs and so they are not in the same category.
My drum sander was becoming one of my least used machines in the workshop, as the traditional sandpaper clogs and burnishes so easily, negatively affecting the finish and requiring hand sanding or super frequent paper changes. The Mirka roll is fantastic, it chews through hardwoods and even when fillers/adhesives are present it barely clogs. Highly recommend.
The best hand sander I have ever used, very comfortable in the hand, very flat and plenty of holes for vacuum dust removal.
Purchasing several different Mirka items was a breeze, easy to order, and shipped very quickly.
Best Abrasives deliver on time every time and have a huge range of Mirka products that aren’t available elsewhere. Competitive pricing and realistic freight charges to rural areas. Don’t think about ordering from Best Abrasives just go ahead and do it, you wont be disappointed.
I am a painter and bought this after lots of research. I have not regretted the purchase and sanding or removing paint has become much quicker and easier. Using Abranet, galaxy or iridium sanding discs make light work of any job. I will definitely buy more Mirka products, Great quality
Recently purchased this for my DS-1632 drum sander. Used for about an hours work before it tears from the mounting clips, rendering the belt unusable. Sanded wonderfully, but won’t be buying again if this is the standard.

These are great for sanding aluminium before polishing, they last heaps longer than any others I've tried
Absolute necessity for any buffing or polishing (either with compounds like polarshine, or other substances - carnauba, beeswax, etc). Phenomenal quality hook-and-loop backings, so no more pulling and degrading of the backing to the machine (or having your pad flung off!)
Still getting to know these products and their use (using on wood and epoxy), but so far very pleased with the results. Non messy and beautiful streak-free results, takes it to the next level from just sanding and polishing, even when compared to a 2000 or 3000 grit pad.
