Review on 🔧 WALTER 15W456 ALLSTEEL Flap Discs - 10 Pack - 60 Grit, 4-1/2 in. - Metal Deburring & Finishing by Michael Shim

These hard drives don't interfere. I have a set of 4.5" 80 grit discs that really make beveling and steel prep a breeze. Add to that a powerful grinder that doesn't mind a hot dinner like a Metabo and you have a great tool. for work. They seem to take longer to wear out than today's cheap petal discs you can find elsewhere. They stick together, wear evenly, bite hard when you need to remove material and leave a great finish with light pressure. I think they last longer than the giant flip discs we had at the store even though they are thinner than regular flip discs. I'm still skeptical about the price, but it will take me quite a while to repair 10 pieces. those discs, so that's certainly valuable. A good buy and if you have a quality grinder that runs smoothly on its own you will be happy to work with these higher quality discs.
