I have been comparing different band file belts restoring my 79 F-150. There is tons of rust I have welded patch panels and they honestly don’t last very long at all. I’d buy quantity over these. You’re paying for the 3M name

Over the past few years I find myself only using 3M Cubitron abrasives. When I do the math it saves me money and time. Paying 1.5-2.5x the price for something that cuts better, faster, and lasts 10x as long is a no-brainer. I love Cubitron in every form.

I was nervous seeing cracks in the belts and sure enough the grit just couldn't hold on.. Ground down one small weld before it wouldn't cut anymore.. this $6 belt cut for all of 10 seconds before all the grit was dust in the air

Cut fast. Wore down fast than expect. Still a decent product.

These are amazing for my belt sander. So far they're they best I've tired, with the Makita ones being second.

Have to admit, I've given this belt a hot supper a few times, it's totally come back for seconds.Outlasts all the others I've tried and puts the cheap ones to shame.Totally worth it!
