Diablo makes great saw blades, but their sandpaper discs stink up the place.

The reason is that they stop adhering to the random orbit sander way before they’re worn down, and go flying. That’s with my previous 5” sander, a Craftsman, and my current Makita (which I recommend highly, by the way).

The ones to buy are 3M. They last a long time and don’t have that problem at all.

I used to use psa paper and thought I was saving money. I got a new sander so I gave H&L a try before converting.

The H&L last much longer and actually ended up being cheaper.

I good value are these-

Yep. Diablo is crap. However, there are dozens of quality options. The store brand disks CWWoodworking linked to are good for the price. For top-notch products, look at Mirka (both Abranet and Gold), Klingspor and other premium brands. They cost a bit more up front, but are very economical in the long run. For really long lasting disks check out alumina zirconia instead of aluminum oxide.

Hah. I’ve never heard of those brands. Good to know. Thanks.

3M is what they have in the hardware store near me, and Home Depot sells Diablo.

These days I buy mostly 3M, Festool, and Abranet, unless I find a hot deal on some other brand. I have some Diablo discs and haven’t had the same trouble but still I prefer 3M.

I haven’t found anything to match the performance of Klingspor discs. I get the VD series cream colored discs, and they last for about 45 minutes of sanding. Velcro holds up well. Reasonable price too.

This is one thing I have been struggling with recently… I usually buy the Diablo disks, used to be Norton disks, because they were the ones available at the big box stores, and I usually just bought what was in front of me. Easy, no real thought, other than grit.

But, recently, I’ve been burning through too many disks and feeling like I really need to up this part of my game.

My first question would be, given the choices, which abrasive to buy? (I do a lot of work with varied woods, everything form pine, to cherry, maple, walnut, mahogany, rosewood, etc. I also do a lot of finishing with polyurethane, shellac, BLO, etc. Those are most of my uses… Don’t do too much metal work, and only occasional plastic stuff)....
