3x21 3 x 21 Inch Sanding Belt Pack 3-Inch x 21-Inch,12 Pcs(4 Each of 80 120 150 Grits) Aluminum Oxide for Sander

Great price on these thanks to this seller. The quality is actually really good and they last awhile. Very durable belt's use them for whatever you need you will not be let down

I was pleasantly surprised with how well these work. They were a great fit and seem to be well made.

The quality/value of sanding belts can be judged both on how long they remain effective while sanding, and on the uniformity per labeled grit, against the cost per unit. These belts compare very favorably on cost (roughly half) vs. another manufacturer whose belts I have previously been using, and the uniformity of grit is near as good as far I can tell with just a visual inspection. However, they definitely don't last as long, but the longevity comparison has been more than half, so they are still an attractive value. I haven't kept good enough data to precisely quantify the value advantage, but if forced to guess I would say they result in a savings of maybe 10 to 20% overall. As a consumable commodity, just expect to use more belts per project than if using premium belts. For context, I'm using them on a Rigid oscillating sander, with hardwoods and BB plywood edges.I have not experienced these belts separating at the joint as other reviewers have mentioned, but even premium belts that sat for over a year have separated on me relatively quickly when put to use (I had two from the same batch do that). Neither resulted in damage to my oscillating sander, and I was able to fasten those two belts back together for full functionality with a Tyvek patch cut from a mailing envelope, adhered with ordinary Elmer's glue (in place of the original joining tape), so for me any future belt separation would be inconvenient, but not a big worry. Perhaps reviewer's whose belts separated had received belts that had aged in a warehouse too long? And perhaps machine damage is a bigger issue depending on type of machine. Obviously, that's speculation, just things to think about. In my own experience I've worn out three of these particular 4x24 belts so far with no separations, and I consider the value they offer to be above average. The grit range (80, 120, 150) matches what I use most, they fit my oscillating sander perfectly, and none had problems tracking.

3 grit types at a good price - works for me!

These belts worked great, i recently replaced a worn out 3m with a new that's shredded within minutes. Use these several times holding up very well. I would definitely recommend ten times the belts for the same price!I also like that it's multiple grit package.

I bought these for stripping several layers of latex house paint off an old wooden garage door. Given the price, they did a fantastic job. After about 3 panels, they started to clog up with paint, but given the nature of latex paint, and how the heat generated by friction softens it, I'd wager a guess that even the expensive belts that they sell at Lowe's would clog up as well

4x36 Sanding belts performing as they should. Prefect fit for my Delta Belt/Disc Sander. Well packed and prompt shipping. Thanks!

Fit perfect. Just what was expected. Good quality.
