3 x 18 Inch Sanding Belts, 40 Grit Aluminum Oxide Belt Sander Belt, 3x18 Belt Sander Paper for Woodworking,12 Pack(3x18in, 40 Grit)

This product does not deserve any stars on any category. 3 belts failed within 3 square feet of sanded deck. Two seperated at the seam once the belts heated up. Presumably, they separated due to poor glue quality. One belt split down the middle after it the seam began to fail, causing a jam of the torn belt in my sander. Inspecting the abrasiclce surface of the belt, it appeared to have barely any wear. If only the seam would hold up, it might be worthy

I have read the ratings on this product, and this is a 4"x24" sanding belt, and seriously after reading the 1, 2, and 3 star comments, it leaves me scratching my head.When working on body work on heavy equipment and other big machinery and also doing hard work especially when using 36 grit, which requires the motor to work very hard, I cannot usually get 3M or Craftsman or Diablo to stay together without separating for 30 minutes to an hour of continuous use, and so far these sanding belts have delivered the same exact performance.I’m using model 362V porter Cable sanders, with the 12 amp motors, and the trick to not separating the belts is not to put pressure on the sander, if anything lift it a little bit, when the motor can rev up, you are still cutting the same amount of material, but putting less friction on the shoe between the rollers that drive the belt. This reduction in heat will greatly save the belt life especially with 36 grit paperAnother tip not to do is park the belt on the hot shoe between the 2 rollers when stopping the belt when you are done, as the shoe can get rather hot and the metal sometimes turns blueish due to the heat it is under, and if you park the glue seam on the steel shoe, expect it to separate, no matter what brand you buy. These are the shoes I am talking about, and in normal use these shoes can reach temperatures in excess of 540 degrees F:https://www.amazon.com/gp/product/B00ENNYT1Q/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1Another way of doing this is immediately after using the sander, undo the belt tensioner and remove the belt when not in use.Hope you find this useful, yeah, this is my wifes Prime account……………………….

The seams of these belts are very poor quality. It seems as if the adhesive just gives way with any temperature increase. Do not waste your money unless you are able to avoid heat friction while sanding (that's a joke).

We needed to sand several doors in our home which over time (and excess rain), have been sticking. I've had a total shoulder replacement of my right shoulder and had great difficulty closing doors with my left hand. My husband finally listened and we sanded 6 doors. I'm extremely happy with this product!

I was hesitant to get these. I've always used the brands available at stores like Lowes and Home Depot. I really didn't feel like driving to either though. They worked way better than the ones I've always gotten from them. None of them broke! Normally when using them they eventually would rip at the seem. None of these did. The price is also far cheaper than those. My new go to!

These were such poor quality. 7 of the 12 snapped within just a couple minutes of trying to use them. One wasn't even a full 21 inches to even get on the sander. Two were missing. Definitely don't waste your money

Dont waste your money on these belts once they heat up from sanding they may last 5 min when they fly apart at the glue joint maybe a good value if it was 100 belts for that price

I have been carpentering for 52 years and these belts are the most inferior product I have encountered. A few of the low points. The belts are undersized! They are difficult to put on when the tension-er is released because they are not long enough.. When you want to change belts, after you open up and release the tension-er, you can't remove the belt by hand, you have to cut them out!. One belt lasted 2 minutes, exploded into pieces and ruined the drive roller on my belt sander. I could list a few other things, but I think you got the idea. Don't buy these
