Mirka Abranet grit chart.

All holes, no holes. The dust leaves the way it came.

Abranet is abrasive on a polyamide net instead of paper. Mirka says no sanding particle is ever more than half a millimetre from an extraction hole, which is why a vacuum-connected Abranet disc stays clean on materials that pack solid paper in a minute: drywall mud, filler, soft paint, resinous softwood.

It is P-graded, so the same caution applies as for any European paper: above P220 it runs coarser than a CAMI sheet with the same number. Abranet Ace puts ceramic grain on a finer mesh for longer life on hard finishes; Abranet Ace HD puts ceramic on a reinforced mesh for heavier work.

Abranet or paper discs?

Abranet without extraction is just an expensive disc. Hooked to a vacuum, it doesn’t care where the holes on your sander pad are, it doesn’t load on drywall or filler, and it lasts long enough to close the price gap. On clean, hard stock with a sander that already extracts well, a good paper disc like Mirka Gold or Festool Granat cuts just as well for less.

Questions people ask

What is Mirka Abranet?

A net abrasive: grain bonded to a polyamide mesh instead of paper, so dust is pulled through the whole disc. Mirka says no particle is more than 0.5 mm from an extraction hole.

Does Abranet need a vacuum?

To be worth it, yes. The mesh is built for extraction; without it, the dust has nowhere to go and the price advantage over paper disappears.

What is Abranet Ace?

Mirka’s ceramic version: ceramic grain on an ultra-fine mesh. Ace HD uses a reinforced mesh for heavier work.
