Used to grind down spot welds. Works great but don't get too carried away, they remove a lot of metal very quickly. They last quite awhile too.

These belts are made better than the cheaper belts on the site. They worked great for sharpening mower blades. I will be buying them again.

Works great on my airtool and I can access areas that other tools won't fit. Especially in small dash areas, or exhaust tubing.

Zur Qualität der Cubitronreihe muss man nicht mehr viel sagen. Überdurchschnittliche Standzeit und gutes Schliffbild.

I always bought cheap belt for my belt sander and they cannot even last 2 spot weld. Those one are really great. They last a long run and they sand quick. They maybe costy to buy one shot but in the long run you will save in lieu of buying cheap one everytime. Fitted my princess auto powerfist 3/8 x 12-9/16

wer ernsthaft etwas schleifen möchte, sollte gleich etwas mehr Geld ausgeben und diese Bänder kaufen. Der billige China Schrott taugt nix.

Unfortunately it only lasts as long as other brands removing spot welds. The only real benefit it has is the belt is non directional where as the others I have tried are directional.

These work well and hold their abrasive ability much longer than any others I've tried.

Im used to using cheaper belts but bought these to try. Very good belt you need to use caution to avoid over thinning of metal because this particular grit removes metal from rusted areas of auto panels, spot welds very quickly .More so than than the cheaper belts I have used.
