KSEIBI 4-1/2 Inch Angle Grinder Disc - 10 Pack Metal Grinding Wheels for Stainless Steel & INOX with 7/8-Inch Arbor - Depressed Center Design for Smooth Grinding - Perfect for Metal Fabrication, Welding & DIY Projects

Great productArrived on time. Wheels are balanced and did not wear out too quickly.It okayThese lasted a long time, but they seemed too hard to actually cut well. Some discs disintegrate in no time, but they seem to cut well. These were almost indestructible and I think in a lot of cases the only reason the metal was ground down is because it got so hot it turned red and melted away.I haven't had them long but so far they are cutting, reshaping, smoothing, and just plain metal removing like a champ. I have a few students that I am mentoring , you can tell the difference between what they don't mind using and what they don't want to use for metal removal. I am sure they will be buying your KSEIBI 4 1/2" 641006 1/4" grinding disc for their own personal angle grinder.Works greaGreat product had no problem with them worked greatNot well manufactured for multiple use. You can use the wide surface of the disc and get limited applications or use the depth side and burn one disc up in one setting.
