Great discs. I have had others that have broken easily or the hole was a tad bit off centered. These ones are great. They last longer and the price is reasonable.

Good fiber discs and a great value. Only downside is that if you’re running a guard on your grinder it’s a tight fit since these are 5†discs and you get material buildup inside your guard. They don’t last as long as the 3M Cubitrons but they’re great for wise flat surfaces.

A good friend recommended this application to my grinder, {flexible pad/disc plus Fibre Disc} and I'm glad he did.seems to work faster than the stone disks I was using before, and these seem to last. but a thought occurred to me, If manufacturers made this where you could remove the outer used portion and then mount said disk to a smaller grinder, I would buy a quality and quantity over current offers!

These are tough rugged discs that work great and last surprisingly long given the speed of the air sander I'm using. But be aware they are somewhat brittle and will break sometimes if you hit a crack or something like that or really jagged metal edge on. Just try not to hit anything with the edge at high speed.

This is a great deal, cheaper than any local dealer.

I have never seen a more cryptic description of something ".... Die# 700BB 120, 25 per inner 100 per case Boxed [PRICE is per DISC]" ... are you selling 1 at 54.04, selling 25 at this price or selling 100 at this price?
