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

I was pleasantly surprised by the quality of this product. This is a functional belt, designed to keep your pants up. It is heavy, high quality leather, and the buckle is also heavy duty. It has a nice design, but nothing too elaborate. If you want a belt to wear with your jeans that does the job, this is your belt.

I have an older Craftsman benchtop belt sander. Lately, I have been unable to find the 4x36" belts that fit. If I do manage to find them, they are overpriced and only available in 80 grit. I was pleased to find this assortment pack on Amazon. Since it contains 3 of each of the grit size belts I use most often, it should be a long time before I need to reorder. The price is unbeatable too (only slightly more than the home improvement store wanted for an 80 grit 2 pack). The belts fit perfectly on my sander and appear to be very good quality. So far so good.

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.

I’ve used both grits and they seem to be well made and are holding up great.

Works well, a lot cheaper than In store products, very good quality!

Using the 1st belt now, working good so far. If this continues, the variety of grit and number of belts make it a great buy!

Sanding old oil based paint off of old oak gymnasium floor: so far so good. Seem to be very durable as I’ve used for 1 hour straight and the still look/feel fairly in scathed.

Would purchase again.

Gute Qualität!

Perfect

This 60-pack of 1/2 x 18-inch sanding belts is a solid choice for anyone doing frequent detail sanding. The belts fit well on my compact belt sander and hold up decently under moderate use. Grit consistency is reliable, though a few belts wore out faster than expected during heavy-duty work. Ideal for woodworkers or DIYers who need a large quantity at a reasonable price. Not premium quality, but very practical for everyday tasks.
