What do you guys thing of 3M 372L Micron Belts

[skillgannon]

What do you guys think about them. I bought a single 60 micron and it really works great. I thought I would run it by you guys before I buy a pile since they aren't super cheap. Compared to AO it cuts faster and last longer with no belt bump. It also cuts faster than gators. Does anyone use them? Are the finer grits worth it?

Never used a belt version. For what it's worth - a folder maker at Ashokan (I forget names) handed some of the 30 and 90 micron out, but in the shop roll format. It was suggested to be cut into very thin strips and used "shoe-shine style" on the inside of lanyard tubes or on small parts. The flexibility of the backing permitted this usage. On a belt, I would be concerned about it bunching up and washing out sharp edges, but that's entirely conjecture.

It has a thin but stiff belt. I think it's a bit stiffer than J-weight.

I use the 80 micron and 20 micron... they are incredible! way superior to regular sanding stuff

I bet it was tim Wright...

I have a few of the belts but mostly I use the rolls and PSA backed sandpaper, as mentioned it is superior to the Rhynonwet and other abrasive Papers
