These grinding wheels work well and are a good value and last as long or longer than many that are way more expensive.

I have used this brand of grinding wheels in past and they’ve worked great. I don’t know if I got a bad batch but 7/10 of these wheels have been way off balance and I’ve had a horrible vibration until I grind them down to about 1/3 the size and then there fine.

I bought a box of the type 27 AC24S Part# 627140. Running at 8500 RPM on aluminum pipe and it loads up immediately. Super disappointing. I use SIGNI brand for 4.5 inch, but they don't make 7" discs for aluminum. These perform like a regular wheel. Will be returning these.

First off, the discs I received were PN: 627070 instead of 627060 as listed in the ad. The discs were still marked as "premium aluminum" so I went ahead and gave them a try. They load up with aluminum terribly bad (see picture). As bad as if you were using a regular steel disc. Once they load up they will hardly grind at all. I have other brands here at the shop that are much better. I will be returning these.

These grinding wheels came just in time. They match the description perfectly. They work great when cutting things flesh to the surface. Very happy with this product.
