3/8 x 13 Sanding Belt, 40 Grit Aluminum Oxide Sanding Belts, Belt Sander Paper for 3/8x13 Inch Mini Belt Sander, 24 Pack(3/8x13 Inch, 40 Grit)

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……………………….

I bought this because we are sanding our small-medium porch and I expected to use a lot of belts, we used about 10 of them and not a single one broke at the seam. I was worried that might happen because of some of the reviews said that happened a lot. These belts lasted longer than the ones they sell at Home Depot or Lowe’s. I am very satisfied with this product and I’m glad a have a ton extra for future projects.

These do the job and seem to last. Good buy.

So far, so good. They were a little tight, but went on, and seem to perform admirably. Make sure you get the direction right.These are for the 2 1/2 x 16" belt sander

Handy sanding belts for those hard to get at welds. They hold up well if you don't over due the applied pressure needed .

I have no first hand experience with these sanding belts other than listening to my husband sanding the stairs for 4 hours today. This was the first time he used this particular brand and he actually made it a point to tell me these were the best sanding belts he's ever used. He said they last much longer that the other brands he's used. I bought him the 40 and 80 grit packages. Today he used the 40 grit. Normally I have to ask him about the stuff I get him and he usually says it's ok. These I didn't have to ask about he just volunteered the info.

So these are supposed be 40 grit. Brand new they feel like 60 grit. After 5 minutes they feel like they became a 80 grit and then another 5 minutes they feel like 120 grit. I felt like I was really doing a lot of work for very little gain with these belts. To make sure I wasn't loosing my mind I stopped by my local HF and bought some 50 grit belts. The 50 grit from HF out performed these 40 grit by leaps and bounds. I had about 30 square feet of wood left and ran the HF belts about 25 square feet. Changed out the belts to one of these 40 grit and all it did was clog up and create a lot of heat. I switched back to the old used HF belt to finish the job. You get what you pay for with these.

Great price and fast shipping

These sanding belts are almost impossible to find in my area so it's wonderful I can get them here and at a good price also.
