I buy hundreds of these now after trying so many inferior other brands

I've worked as a welder/ fabricator for 25 years. Over half that time I spent working with stainless and grinding/ blending welds. I've used many different brands of aluminum oxide flap discs and sanding discs. The Lehigh Valley ceramic flap disc is hands down the best performing disc at a fraction of the cost of competing brands. This disc cuts very well, but more importantly, it retains is cutting ability much longer than most flap discs. Most flap discs cut great for a few minutes of grinding when they're brand new out of the box, but quickly become dull, which only heats up your angle grinder and slows down your progress.
I worked at one place where a sales representative for one of the big name companies came in and wanted me to test their disc against this Lehigh Valley ceramic disc. Their disc was also ceramic and was supposed to have tiny triangle shaped particles that never lost their edge. Their disc also cost twice as much. So my employer had a stopwatch ready, and two coupons with an equal size mig weld on each. They timed me as I ground off the weld on each coupon, one with one disc, one with the other disc. It turned out, there was literally no difference in the amount of time it took, or the quality of the result.
It was obvious to everyone present that there was no reason to spend the extra money on the overpriced disc.
I know first hand that these Lehigh Valley ceramic flap discs are the absolute best bang for your buck. Im writing this review after purchasing these from the Lehigh Valley website for the first time. I had a use for flap discs at home and I was tired of buying the junk I can get locally that cost as much or more.
