worth the 3m price
3m. Costs 3x the price but lasts 3x as long. Great belts.

Excellent quality
My husband has been the same one for a hot minute. Stays in place and lasts a long time. He normally goes through several in a day for his projects.

Best belts you can get
Best belts you can buy. Work great for grinding down welds or cleaning rust off of hard to reach areas.

The expensive becomes worth it
I don’t know what cubitron ll is, but it sure performs well grinding hard steel. High or low speed with prolonged grinding on edges, corners and surfaces, these belts stand up showing little wear. Bi-directional. Worth the higher price compared to cheaper belts that quickly wear out or fall apart. These belts last.

3m is solid stuff
You can't beat 3m as far as sanding products. Lasts twice as long as everything else out there. Recommend 100 times over

My power file gets used almost daily & I've always been frustrated at how quickly my previous belts would wear out & break. I've only been using these new belts for the past couple days & they are worth the money. They remove material much faster & with hardly any pressure needed.

Fungerar extremt bra! Vanliga filbälten håller i kanske en minut om jag ska slipa ner en svetsfog, den här har hittills klarat av att slipa ner ca 40 cm svetsfog, plus två skruvskallar samt slipat skären till gräsklipparen

These belts last a long time grinding down welds on my restoration project. With my first belt, I have ground down approximately 6 feet of stitch welds, and that same belt is probably good for another 4 feet of welds. You don’t have to push hard just use very light pressure. This belt is very expensive. Would like to find it cheaper somewhere else.
