I was surprised how long these discs last compared to the cheap ones I usually grab; took off heavy rust from a steel beam without the grit wearing down.

Brian ★★★★★ Oct 20, 2026

Cut through a thick layer of rust on an old trailer gate in under five minutes, and the disc hardly looked worn. The resin bond holds the zirconia grit tight even under heavy pressure. Exactly what I needed for rapid stock removal on tough metal projects.

Been using these on a stubborn rusted steel frame and the zirconia fibers chew through it way faster than the old discs I had. Weld grinding is smooth too, they hold their edge well and don't glaze over halfway through the job.
