Customer Reviews

Rated 4.3 out of 5 by 165 reviewers.
Rated 5.0 out of 5.0 by Getting a bad rap by some I didn't read through the reviews when I purchased this, it was more of an impulse buy when at the store. When I gave it a try cutting through pavers I thought it was defective, as the new 2.0 amp batteries I had were both dead after very very limited use. I picked up a 4.0 amp P108 battery and this grinder is AWESOME. I've made plenty of cuts without issue. As with any grinder don't try and force it to work faster than it should by applying excess pressure as that will shorten battery use time and cause it to get hot. On a side note: Wear Goggles when using, don't be a Cowboy. At first I wore safety glasses and still managed to get a small but quite painful piece of stone in my eye. Goggles are a must.

Rated 5.0 out of 5.0 by great tool Love this grinder got it to cut fencing diy project. Saved me to much time! Cuts everything I've thrown at it! Also sharpen lawn mower blades. i didn't have problems with going through battery's to fast. Love ryobi tools! June 27, 2016
Rated 5.0 out of 5.0 by Great product!!!! Light weight, powerful, and very durable. Would recommend this to anyone! Only downfall is that is sucks batteries very frequently. August 9, 2016
Rated 5.0 out of 5.0 by Great grinder Needed an angle grinder for a few tile projects I was doing around the house. This worked great on a few bullnose edges I needed, as well as a few cuts for outlet boxes. Loved not having a chord. Highly recommended. August 7, 2016
Rated 4.0 out of 5.0 by Nice Cordless Grinder I purchased this grinder because I was working on a fence and I had to cut some old galvanized fence post down. This grinder did the trick, it had enough power to do what I needed it to do without any problems. August 16, 2016
Rated 5.0 out of 5.0 by Got the job done I needed something very basic to cut off the toughest locks in a storage yard that a bolt cutter won't cut. This little model does the job and for under $100. August 2, 2016
Rated 5.0 out of 5.0 by Good Investment I was timid as to 18 volt using this tool. I was impressed at the length of time a battery lasted. August 9, 2016
Rated 5.0 out of 5.0 by Good tool I needed to cut some steel signposts but didn't need a heavy-duty grinder and rarely have a need for the tool. This cordless grinder worked out well and let me go into the field for my work. For everyday homeowner work this is a good product -- I'm not slamming its durability or strength, it's just that I've only used it a few times for jobs that require medium strength capabilities. The tool handle holds the wrench used to change blades, which is very convenient. July 19, 2016
