4" X 5/8" - 11 進口不鏽鋼壓紋杯 .012 最大 RPM 8,500

I needed a serious brush for stripping rust off some steel beams, and this 4-inch cup with the 8,500 max RPM rating handled the heavy grinding without slowing down. The stainless steel crimped wires held up better than the cheap carbon ones I’ve tried before, leaving a clean surface for paint.

The 5/8-11 thread arbor screwed onto my angle grinder without any adapters needed, and the crimped wire held its shape through a full afternoon of stripping paint. At 8,500 rpm max, it chewed through rust fast enough that I finished the job in one sitting.

I needed to remove some tough weld splatter off a metal gate, and these stainless bristles handled it without leaving residue. The 5/8-11 thread was a perfect fit for my grinder, and the 8,500 RPM rating gives me confidence to push it.
