Review on 7" Diamond Grinding Wheels For Concrete Or Masonry, 24 Turbo Segments, 30/40 Grit, Medium Bond, 5/8"-11 Arbor by Chris Benton

I an not attest to the durability of the wheel. The fit and finish of the wheel looked of high quality. Unfortunately, I never used the wheel as I could not find any information regarding the maximum RPM the wheel could be used at. My angle grinder operates at 8500 RPM and is NOT variable That said I returned the wheel through Ebay due potential safety issues. I would consider purchasing the wheel if there was information stamped regarding maximum RPMs the wheel can be used at.Thank you.
