Sungold Abrasives17202 36 Grit Aluminum Oxide Fibre Disc (25 Pack), 5 x 7/8" Center Hole

Like others, mine was over shrink wrapped so they were all warped. This doesn't make them unusable, it makes them harder to put on. Otherwise, they work just fine, no better or worse than any others. 1 disk is smoothing 12' x 8" of well seasoned, very rough cut, red oak and I quickly finish with an 80 grit.

Good enough.Gets the job done .

Worked for what I needed them for. They don't last that long as far as what I was using them for. But for the price you can't beat it.

Grinder discs do good job, not quite as good as a major brand like 3m but still worked well! Money savings is good on this product vs major brand. Will buy again!!

Cheap price and decent quality. For me it is these or spend 8 or 10 bucks on a flap wheel that will last about the same time as 6 of these. But the kicker for me is that everytime I put a new one on its a fresh disc rather than a wearing down flap disc. Meaning each piece I grind takes longer and longer as the flap disc wears down. 1 of these does one unit for me.. could push it to 2 units but they're so cheap I just put a fresh one on for the speed. And yes it is faster to change these out than keep on a wearing down flap disc.

Nicely packaged..good discs. Can’t say much more, they are the grit ad advertised and work well

For the price I can’t complain. They work as good as any grinding disc I have ever used

There were pretty horrible. If we were able to get 60s of use out of them before they shredded or exploded, then we were lucky. Went through a box of 25 in an hour. %100 would not recommend
