Zirconium Universal Grinding Disc 40 Grit 115 x 22mm
These were cheap and are effective. Durability seems good versus the price.

I used this disc on wood as well as steel tube and it worked ideal on both

Not impressed with these for the price, I have used much better discs which cost cosiderably less.
The biggest issue was that where other discs will simply wear out in time before going through to the backing material, these broke up & pieces fell off rendering the disc unusable before the friction material had been used fully.

Better than a file...Just.
These are very poor quality flap discs which wear out after only a few minutes of use. Don't bother buying these for an industrial or engineering use. In fact...don't buy them for any use, there are much better discs to be had, Blue Line for one.
