Rated 4.0 out of 5 by 50 reviewers.
Rated 1.0 out of 5.0 by nice try Ryobi I liked the design of this grinder. A 4 1/2 inch grinder with a trigger at a decent price is hard to find these days. Usually they have barrel bodies and switches close to the blade. This ryobi was light, easy to use and had a good feel. However, I bought it for repointing my brick house and went through two of them before I bought a much more expensive Milwaukee. On the plus side they have a 30 satisfaction guarantee and both grinders blew up before that expired. November 6, 2006
Rated 1.0 out of 5.0 by Brushes I bought this AG451K 4.5 grinder and in les than 1 day the Brushes went on it. I cut 2 boldts of a swing set 1"long by 3/8 thick. You tell me what good about this product? April 20, 2009

Rated 4.0 out of 5.0 by Great grinder for the price I had my doubts when I bought this angle grinder, as I've owned other Ryobi tools that haven't held up. That being said I don't use a angle grinder everyday so I didn't want to spend that much on one. Boy was I impressed with the power of this thing I've been sanding down weld joints like butter. I also like the fact the handle rotates for ease of use in many different angles and positions. I don't know about everyday use since I don't use mine like that but if your a weekend warrior this thing rocks. January 11, 2015
Rated 4.0 out of 5.0 by Impressive performance I'm a welder/metal fabricator and have used many grinders from various big name companies. I thought I'd give this grinder a shot because it's cheap compared to my other grinders I have. Performance and ergonomics on this grinder have won me over. I use it daily as a light duty grinder. Mostly deburring parts and knocking down small welds. It doesn't have the amperage needed to hog out bevels and flush out welds in a timely manner but is very capable of doing so. I have found it to be very sensitive to an abrasive wheels balance. If your abrasive wheel isn't quite balanced the grinder will vibrate quite a bit. I have had no issues using this grinder with cut off wheels. I actually prefer using it to cut with for the fact that it's lighter than my other grinders and it's lower amperage so it doesn't want to yank itself out of my hands if it starts to get wedged. Most impressive of all is that it has outlasted some of the more expensive big name grinders I have had the displeasure of owning and using. September 10, 2011
