Just got my hands on these EZARC ceramic flap discs, and wow, they’re a beast! The 40 grit is aggressive enough to chew through stainless steel and cast iron like butter. No more struggling with clogged or worn-out discs mid-job.

Heat dissipation is insane—no burning or overheating even after prolonged use. Compared to my old zirconia discs, these last way longer and cut sharper. The Type 29 backing is a nice touch for contouring edges, especially on weld beads.

Price-wise, it’s a steal for the performance. Only gripe? No finer grit options, but for heavy grinding, these are perfect. If you’re tired of replacing discs every other project, give these a shot. Worth every penny!
