These Mirka Ultimax Ligno discs work great on hardwoods like oak. The dust extraction is excellent, I highly recommend!
Used them for medium to light sanding of Travertine floor tiles - in a DIY job - before I could use a Travertine sealer (Gloss)
These little Mirka Galaxy sanding disks did a great job - I used many other brands but none did a good job and all tended to clog quickly...
Absolutely recommended....
