Crappy Sanding Discs Or High Resin Content Mdf??


ive been back in trim mode for 3 weeks and processing quite a bit of mdf... i sand all ripped edges either by hand for edges with a round over or with the sander for square edges..

ive noticed my sanding discs arent lasting as long as they used to.. trying to figure out if its do to cheaper qualiy discs or does mdf flat stock with a high resin content wear out a disc quicker.. .just wondering

i mainly use sia discs or norton, just recently picked up some freud diablo discs which are a little better than the sia's. gator is the other brand available here

Don't like to guess if it's the MDF or the disks in this particular instance, but just for reference I used the Mirka Gold disks before I switched to Festool. If you order the 50 packs from Amazon they're very reasonable and I was always impressed with their durability.

I haven't been impressed by the Freud discs and Gator is worse IMO. I like Norton better and Mirka best.

The disks on a sander with a vacuum attached will always last longer that one without.

I have not seen an mdf panel that clogs paper at an unreasonable rate.

I know that when I use normal MDF, it does seem to bother me more then when I use the Premium or Ultra-Lite. In fact, the premium and ultra lite really don't bother me at all.

+1 for Festool discs, and even better with dust extraction.
