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.

Rated 1 out of 5 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.

These are the worst flap discs that I have ever used and certainly not worth the Â£5 cost. They only lasted several minutes before becoming completely useless and I've bought ones previously for as little as Â£1 that have been better. Having tried many different makes of disc I have found Dronco ones to be the best (no, I don't work for the company) so save yourself the hassle and buy them instead.

Bought this to grind down weld seams, it works but takes a lot of grinding and the outer edges of the disc have worn already. At Â£5 a throw I might give ceramic discs a bash but Screwfix don't sell them.
