You may have noticed this peculiar light blue colored abrasive in some of our recent photos. First, even though the name is "Granat", it is not made for Granite or stone material. It's actually made for use with wood.
"So what's so special about Granat", you might ask. Well, Granat is a hybrid abrasive comprised of hardened aluminum oxide with a ceramic grit. This hybrid approach causes Granat to retain it's cutting edge much longer than any other abrasive. Even though Granat uses a stearated coating, it does not contain wax. Since it lacks any type of wax additive, there are not issues with water-based finishes that you may have had with other Zinc stearate abrasives.
Most of you who own Festool sanders and are sanding wood probably use Rubin abrasives. While Granat is going to last longer than Rubin, it is has a thinner backing material and produces a more aggressive scratch pattern. For this reason, you may want to continue to use Rubin if you are sanding a lot of corners or edges that may tend to snag the abrasives sheet since Granat would be more prone to tearing.
Granat abrasives will also be available in a roll of perforated sheets. The perfect size to use for hand sanding. These sheets incorporate a foam backing to allow the abrasive sheet to conform to the surface of the material.
