Okay, so I've tried A LOT of flap discs over the years (seriously, my workshop looks like an abrasive graveyard). These Benchmark ones? They're legit.

First off - the price-to-performance ratio is insane. I used to drop serious cash on 'premium' welding shop brands until I discovered these. Same quality (sometimes better), way cheaper. My wallet thanks me.

The zirconia material is no joke. They last way longer than most discs I've used, especially when working on tough steel projects. The 60 grit ones in this pack are perfect for when you need aggressive material removal but still want a decent finish.

Pro tip: They do feel a bit 'fluffy' when new (in a good way!) which gives you super even pressure distribution. As they wear down, you'll notice more pronounced cutting marks - that's your cue to swap to a fresh one.

Compatibility is great too - fits all my grinders (Dewalt, Milwaukee, you name it). Used them for everything from weld prep to rust removal to general fabrication work.

Final verdict? If you're still buying overpriced big box store flap discs, stop. Get these instead and thank me later.
