Questions & Answers

Will this work for polishing cars

Asked by: SJ
Thank you for asking, SJ. We do not suggest using this grinder to polish a car. We highly recommend using a buffer instead as this grinder may cause damage to the car. I hope this helps and we appreciate your interest in Ryobi! -Keri

Does Home Depot carry 4 1/2" grinder discs with 5/8" arbor?

Couldn't find them in my local (Bellevue, Wa) store. Only 4" discs had 5/8" arbor. There was a tag for one 4 1/2" 5/8" arbor but it was loaded with 7/8" arbor discs. No success finding them on-line. Do you carry them on-line? Looking for metal cutting and tile cutting discs.
Asked by: MrB
My local store carried them sporatically. You might talk to the manager of the store and see if he can get them for you. Also, there are other suppliers that might carry what you need. HD is always my first stop, but I have two other places I look when they are out of stock. Check your local hardware and supply stores, you might be surprised.

5.5-Amp 4-1/2 in. Angle Grinder is rated 4.0 out of 5 by 51.
Rated 4 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 2 out of 5 by from only for grinding and sanding unit has a nice feel but manual states only for grinding and sanding and not for cutting, Also manual states that only offset wheels can be used. When properly installed the strait wheels bought at Home Depot are loose, you can reverse the collet but manual says not to.

Rated 3 out of 5 by from RYOBI switch I have two of these and I love them. I fabricate ornamental iron as a hobby and use them almost every day for sanding, grinding, and slitter wheel cutting everything from I-beams to concrete, but mostly 16ga steel tube. I even run 7" diamond blades, slitters and sanding discs on both, but I have to be careful not to either overheat or overspeed them. I prefer to run them on speed controls, but I'm not sure the switch likes it. Sometimes run them at full speed until they were too hot to touch. I'm impressed. They're still going - one's 5yrs old, the other 1yr. The wrench in handle and snap on guard are great! The size and trigger switch on handle are great. The rotatable handle has not been used, although the tool has been used in all positions. I would rate it 5 STARS but for one thing. I'm about to buy the SWITCH for the 5th & 6th time! I'm about to replace it the third time on each! It's only $5, but the down time, the wait for order, and the dis/re-assembly get quite frustrating. RYOBI can you please upgrade the switch design a little? btw I did not use the last replacement switch with the speed control and it failed quickest! I recommend these all the time because they're SO economical, but always with that switch caveat. Thanks!

Rated 5 out of 5 by from Another great Ryobi product Bought it to cope trim. I use 2 sanding disks back to back. After some trial and error learning to cope, it is now a very fast and accurate way to cope MDF. The tool is perfect for what I need. Powerful, stable, and inexpensive. The only thing I would change is to have some form of braking on the spinning wheel to stop the wheel when the trigger is released. My tool snob buddies always look down at my Ryobi gear, but every Ryobi product I have works well and usually has some innovative features. And with HD"s return policy, I can try the tool and return it if it is not good enough. But I have never returned a Ryobi product, including this grinder.

Rated 5 out of 5 by from Felt right out of the box Just bought this grinder on a recommendation from a friend. I was pleasantly pleased when I used it. My last grinder purchase was based on motor amps, 7 amps, and name brand loyalty. This was less amps, 5.5, but a great product. 1) Ran much smoother and quieter ,than the one I returned. Sounds and feels like a good product should. 2) I like the feel of the pistol grip, that is can rotate is nice, but not that a big deal 3) Two year limited warranty is a nice plus 4)Comes with a case , a definite plus. DeWalts products usually came with cases, I guess cost cutting has eliminated that. 5) Wrench fits in handle, a nice plus, handy place to keep from loosing it. 6) Comes with a wire wheel and a cup sander, the other brands did not. I am a power plant mechanic so I know tools.

Rated 5 out of 5 by from Good quality grinder. . My old grinder finally died and I needed to replace it. I had a gift card from Home Depot so I went to look at their products. I found most of the little grinders have a sliding on off switch. I don't think that is very safe. I noticed this on has the index finger button my larger grinders have. I didn't want to buy a Ryobi product, I wanted Dewalt or Ridged. I don't know about the other Rob tools but this grinder is very good. I have used it to cut copper, tile, sand steel and wood. The swivel base is a big plus. On top of all the features its also very low cost.

Rated 5 out of 5 by from Good hard working grinder I had the previous version of this grinder for six years. As a handyman It is used frequently. I finally burned it out after going through four 4" twisted wire brushes to grind the paint off a concrete block wall of a gymnasium. It took three days. I've used it for cutting the tops off fence posts, cutting metal, pointing walls and chimneys, cutting tile, sanding, cutting stone, and many other things. I love the control you get with the handle and trigger. You can work with it all day without getting tired. The key to using this or any other tool is let the tool do the work. Don't force it. You will remove more material faster by letting the tool run at speed and preserve the tool as well. If it starts to get hot either give it a rest or let it spin free to circulate air through it. The new one works just as great and has the advantage of the swiveling handle. With a slight modification of the old case and this one is back where it belongs.
