Red Label Abrasives 1/2 X 18 Inch 36 Grit Aluminum Oxide Air File Sanding Belts, 20 Pack Sanding Paper Belts - Weld Removal, Metal Grinding, Woodworking, Knife Sharpening

I think couple of these 20 packs is worth more than the trim sander they work with. But man o man, they take the weld seam out of a square tube and they'll ramp/polish all those places you try to reach. A few hours of heavy use will glass one of these over pretty good.

I wanted to try something other than the expensive name abrasive company out there so I tried these. They fit perfectly but seem to loose their cutting ability somewhat quickly. I can grind about a 1-2" weld with one belt. That seems a bit weak but who knows? Maybe not. I have used 6 and none broke anywhere. The seam is strong.

so far so good.

They're okay, they wear quick. The 3m last a bit longer but for the same price you only get 10. You get 20 of these so I would say they're about equivalent

These work great. I bought them for sheet metal autobody work.

Definitely sticking to red label especially it being made in the USA. Belts last similar to 3m but half the cost. Can get through about 50 spot welds per belt give it take 10.

The belts worked great for bladesmithing.

I am relatively new to the mini belt sander game, I bought a pneumatic sander for some restoration work recently. It came with some belts that lasted all of 2 minutes on metal, I ordered some chinese ones that were about the same price as these which also fell apart very quickly. The Red Label belts lasted a good 5-10 minutes of hard grinding. I dont know if that is good, but its about 20x longer than the others I had for about the same price so I bought more. When they are fresh they make very short work of steel.

Worked great, used some of them to strip paint off of some tight spaces on a wall I'm repairing. Stayed together till they were fairly worn out.

Excellent quality

Parfaitement comme décrit. Job done.

great product

I tried one and it worked fine.
