Calificación de 5 sobre 5 por de Powerful, doesn't bog down. I have had great luck with this and have put over 1000s of hours building with my Ryobi tools, without fail. This grinder has done a lot of hard work, I've gone through dozens of cutoff wheels and grinding wheels and it still goes strong. I own a Haunted Attraction and we build sets that cover over 13,000 square feet. This along with a dozen other Ryobi tools have not let us down with our builds. They have been dropped, stepped on, ran battery after battery through them and still keep going.

Calificación de 4 sobre 5 por de About what you'd expect This was purchased as a replacement for a 12+ year old Ryobi model that finally burned up but didn't owe me anything. It's about what I'd expect. Has enough power for a 4.5" and eats through batteries fairly quickly as expected. If Ryobi would be open to some constructive criticism; I would have liked to see the rotating base continue into newer models. That was a convenient element for working in confined spaces. Also, the wrench storage inside the handle doesn't feel very secure. I'm constantly concerned it's going to fall out and become lost. Maybe magnetic retention can be added in future models.

Calificación de 5 sobre 5 por de Awesome I got this tool last week for a specific job not knowing the availability of exterior plugs for my corded grinder. This was so awesome to not be encumbered with a long cord, The grinder did all that I wanted and I only neede one battery and that was not 100% charged!

Calificación de 4 sobre 5 por de Good tool, just don’t over work it This is my second 18V ONE+ 4 1/2” cut off tool/grinder. My first decided to just stop turning on one day after I had to cut a 6” I-Beam that was about ~1/4” thick. I think that much use was probably a bit much for it given the time it took so will stick to my plugin version for things of that magnitude in the future. The tool worked flawlessly during the cutting so it’s performance was great. The next day when I went back to do some cleanup on the edges it just wouldn’t turn on. Had no issues with it for almost a year prior which is why I had no problem going with another one when replacing it.

Calificación de 5 sobre 5 por de Fathers Day Gift! I had been wanting this for a while. My kids got it for me for Father’s Day!!! I knew I wanted the brushless grinder, and I was impressed at the quality of the tool. Seems well made, and I have the larger batteries which seem to help with the balance of the grinder. I have not used it just yet, but if it’s like the rest of my Ryobi tools, it will be up for the tasks at hand. I have only had 1 tool develop a problem so far, my inflator sounds like it may have a bearing or brush problem develop just a couple of weeks ago. Still under warranty, waiting to hear back from Ryobi on that issue...

Calificación de 5 sobre 5 por de Fantastic Tool I recently brought the Ryobi 18 v cut off / grinder. I have always used a plug in 120v cut off grinder before my purchase. This tool is immediate and powerful. I’ve cut rock, stone, rebar, pvc, etc.. No need to get the extension cord like the plug ins. I recently went to Home Depot and purchased several 20 ft lengths of 1/2” rebar. I took them to my SUV and cut them to 6 ft lengths in minutes, and loaded them easily into my SUV. This tool goes ANYWHERE, easy to use, and powerful. Many uses!!!! Love it.

Calificación de 5 sobre 5 por de powerful I've used this for all sorts of work here on the farm. It is just as powerful as my corded grinder, but I use it more because its cordless, easier.
