They key I’ve found is to not be lazy, change grits. Don’t try to make the 220 or 120 do the job the 80 or 60 should be doing. You’ll quickly put burn wood marks on the paper. I also have found to take lighter cuts than they say you can do, and feed it slower. If you pay attention, the paper lasts a long time and the machine does a good job. Don’t bother trying to cut and fit your own, these pre-cut papers are easy and fast to install and your time is better spent working than fussing with trying to cut your own. Roy
Of course they sand well but are way overpriced. I’m still looking for 3” wide rolls of sandpaper so I can cut my own. Be careful installing the paper and get it tight and when Jet says leave at least 1/8” space on the last slot, you’d best do it! Otherwise the last wrap will slide over and overlap the last wrap then it gouges and burns your workpiece. It also ruins that piece of sandpaper. With the price of them you don’t want to do that many times. Yeah, I I recommend them if you can’t find sandpaper rolls to cut yourself.
Good quality sandpaper with fairly thick and sturdy substrate.
Supermax drum sander comes with 80 grit from manufacturer. A fairly aggressive grit that leaves sanding marks in surface. I thought I would give the 120 grit a try to see if I could reduce the time of final sanding. It does leave a better surface but requires more passes at a shallower cut setting to get wood thickness. I use my thickness planer to get thickness close and allow for any snipe removal. Then the 120 grit sandpaper brings wood to final thickness and ready for final sanding with orbital sander.
have used this and felt backed sandpaper on this drum sander. this paper will tear during use if not careful. roll of felt backed last longer but has to be cut to size with a lot of waste on end of roll. would recommend for sanding little pieces
