Rated 2 out of 5 by from Seems Good, Until You Use It It works well enough and feels good in your hand. Disc changes are easy and the guard is easily adjustable. But the motor housing gets as hot as the surface of the sun. Like you'll literally burn your hand if if you touch it. The 1.5ah batteries last maybe 20 minutes, probably because so much of the electricity is converted into waste heat. This is all under pretty light load too - light surface work on metal. I got it because I wanted to try a cordless grinder and I already had a few Ryobi tools/batteries which I've been pretty happy with. I can deal with the run-time because I have several batteries, but it gets 2 stars because of how hot it gets and how severely I expect that to reduce its life. Maybe I'll end up being wrong, but as long as I own it now I'll just be wondering, "is the day it finally bursts into flames?" Not a good feeling. I wouldn't buy it again.

Rated 5 out of 5 by from Great tool. This is a great tool, hands down. Great battery life (4ah), plently powerful for 99% of any job. Balanced, especially with the 4ah battery). 3 handle positions. Guard that is easy to put on and take off. Torque protection that does not limit the tool (really it just keeps you from breaking something, including yourself). the overall length of the this grinder is great as well, you can spread your hands out and have even more control. I have a corded grinder from another company that I barely use because it's basically dangerous. The torque start twists the tool in your hand, the handle is small and well, it's corded which had become a pain in my life. I've used this Ryobi grinder on 4 separate projects in the last two months and it's worked flawlessly. The latest project was refinishing some outdoor furniture. My wife grabbed a big wire wheel for this grinder and used it to strip loose paint from a table and 4 chairs. A few hours and 5 batteries later, we were painting everything and they turned out great. What was even better is that this was her first experience with a piece of equipment like this and she felt comfortable with it in just a few minutes. I find this a testament to engineering by Ryobi.

What is the thickest material that it can cut?

What is the thickest material that it can cut?
Asked by: Denny
Not sure, but for me it will be the metal clothes rod in my laundry room. Once I take it down, it will be cut and used in a different room. This is one of several planned projects for my cut-off tool and grinder. Most of my future projects involve cutting wood shelves, but the metal rod is probably the thickest material I will cut.

Are the safety guards made of metal? Or plastic?

Are the safety guards made of metal? Or plastic?
Asked by: Anonymous
Hi Anon, I think they're low carbon steel. The case is plastic, but the head assembly is also something like low carbon steel. Regards, Nick

Can I use this tool to put an edge on a shovel or garden hoe? In other words, can I use it to sharpen things?

Asked by: Cliff
Hi Cliff, I've used mine with any grinding blade thing that will fit. I sharpen shovels, spikes, my lawn mower blades and my bush hog blades. Ps. I live in South Carolina with hard Red clay soil. Nick

Can you Use 4" blades or do they have to be 4 1/2?
Asked by: Mike
Mike, thank you for your interest in the RYOBI 18-Volt ONE+ Cordless Brushless 4-1/2 in. Cut-Off Tool/Angle Grinder. The wheel capacity is 4-1/2 in. This means that if the wheel is smaller it should be fine. You will have to make sure though that the arbor is the correct size. Thank you for asking, If you have further questions and would like to speak with a RYOBI Customer Experience Professional, please call, 1-800-525-2579 M-F from 9am-6pm EST. Hope this helps! - Vini
