Andrew D. ★★★★★ Oct 22, 2026

Got through an entire truck frame with just one disc and it's still got life left. The extra thickness on this 4" flap disc really makes a difference compared to the thinner ones I've used.

Alexander I. ★★★★★ Oct 21, 2026

This thing chews through a full day of grinding without the flaps shredding like the cheap ones I used to buy. The zirconia grain on these jumbo discs is noticeably more aggressive on stainless, and they’re still flat and true after a couple of heavy sessions. Definitely my new go-to for weld blendi

Cut through a full sheet of 14-gauge steel with one of these and it barely slowed down—the zirconia grit and extra thickness are no joke. Spent half a day on a rail job and the disc still has plenty of life left.
