POWERTEC1/2 x 18 Inch Sanding Belts, 20PK, 40 Grit Aluminum Oxide Belt Sander Sanding Belt for Air File Belt Sander, Woodworking, Derusting (401804)

These work great. They cut fast and track well also. Made short work of some 110,000 psi steel

They are definitely not as good as the expensive brands but for how much they cost they are great

Long lasting, fast cutting

I have bought these sanding belts several times now because they are durable and they get the job done quickly.

Have used this brand of belt before with good results. This new batch is subpar. The first four belts have failed in the joint after a minute or two of run time. All snaped apart the same way. Have not had this problem before with this brand. 36 more belts to go... don't have much hope things will improve.

Bought the sander at Harbor Freight along with 2 packs of their belts. 1st, theirs is a mix of 5 different grits. I only wanted the most coarse I could get. 2nd, each belt lasted less than a minute. Garbage. I got these and did the whole job which was about 2 hours of sanding on only 2 belts. Much better.

They work quite well, especially for the price. I really put them through some rough scenarios, when I have to use them, so its hard to judge longevity, but they hold up pretty well, compared to others

The belts came on the next day as promised but instead of coming in five neat piles separated by grit number they were all jumbled up. To make things worse, there were 8 or 10 of them that had no marking at all on them, no grit number and more importantly no directional arrow showing how to load them into the sander (kind of important).I haven't used any of them yet. They may be going back in the same jumbled up mess that I received them in.

These have very weak joints and have failed prematurely on me on many occasions. The joints are held together with a thin adhesive that fails very easily and very often....may be ok for light duty applications on soft materials such as on wood or plastic....but not heavier harder duty materials like like steel.

The tape and glue used to bond the joint is not strong enough. You can't increase the speed of the machine or the belts break so quickly.
