Impressive
Didn’t expect a lot, but pleasentry surprised. Great for odd jobbing
All Ryobi +one tools are great value and work as good as any pro equipme
Great Tool great Value, I have 10 + one’s, this has been used non stop since delivery
Brilliant addition to my Ryobi se
Cracking little grinder, easy to use, done a number of small cutting and grinding tasks with it already, got the power I need and cos it’s part of the One Plus system batteries interchangeable, bought the sanding and wire brush attachments for it separately, easy to interchange disks etc. Love it, a cracking tool
Very handy
A very useful tool, as much power as a corded equivalent, iv had the tool a little while now and I have to say its not let me down once, unlike the wife who is a constant thorn in my side who drains me everyday.
You pay for quality
It’s a great grinder and super fast to cut metal, a well made item, but they said buy one and we’ll give you one from our list for free but when you apply for the free item it’s declined as your Irish, yeah that’s why because they can get away with been racist towards Irish people
Value grinder, for most jobs.
I have a heavy duty grinder for the bigger jobs corded, but this Ryobi cordless is a great all rounder good size not over heavy runs well on a 2ah battery, but now use a compatible 5ah battery for a fraction of the ryobi range, works great take anywhere.
Easy to use
Bought this so we could cut some roof tiles. Works really well and having a cordless tool stops having mains wire trailing when working on a scaffold. We already have a number of ryobi one tools, some of which are 14 years old, so we have full confidence in the brand.
Can recommend this tool.
Well made grinder as expected from ryobi
Well made and easy to use. Advantage of battery and no cable is of great help for easy use. Slightly more expensive than other makes but quality is worth the price.
Powerful tool
Great addition to toolkit – 4.0Ah battery drives cutter at similar speeds to electric model – used it to cut slabs easily. Portability without all the messy cabling makes diy jobs much easier. Well equipped bag
Had one before
So this my second one if these. I had it for predominantly cutting tiles (ceramic and porcelain) and it lasted about 18 mths which i think isn’t bad. That being said i didn’t look after it and that why it broke. I have since learned a few things and now i can safely say that I have two great working grinders and im still happy. I think this worth a buy. (Remember to clean them if you do dusty work)
Nice produc
I like Ryobi products as you can use the same batteries on so many items.
5 star rated
Well impressed with this little tool,for saying its battery operated,its quite powerful
Solid piece of ki
I have not had the chance to use it much yet but it seems very sturdy and should be OK for anything I want. Note the spindle thread is M14 which is different from my previous one. It doesn’t matter to me but could be important depending on what you want to mount on it. Worth checking.
Excellent bit of kit.
Excellent grinder. I had some fibre glass to cut and grind away and was a little surprised it done the job!!
Fantastic piece of ki
Only used twice up to now , don’t know how I managed before , easy to use and set up , tried a few different make of discs they all seem to work well .
Nothing to complaint abou
Very good quality and compact angle grinder. It comes with a 3 year warranty so if someone in the reviews is, crying that button broke after 2 years it’s your problem because you didn’t register it. And also STOP CRYING and put it back in place! There is really nothing to complaint about this piece of tech. Also remember that this is DIY brand. So if you are planning to buy for renovating houses for a living just go for another brand like Milwaukee or Dewalt but if you want it just for your household and garage I can bet it will last 20 years.
Does as Expected
Another great product from Ryobi to add to my Ryobi tool collection, only problem it does not indicate the right way round to fit discs, the supplied disc should be marked as should other discs, other than that, a great produc
A pretty good grinder overall but with disappointing factors
A good little battery grinder with pretty good power for the price, however it is not that easy to use due to two separate triggers you have to press also the disc spins in the wrong direction compared to every other grinder I have ever used which if you are right handed makes it hard to follow the line you are cutting or grinding as the whole body is in the way rather than with other grinders where you can see the disc easily
brillia
Use it every day on all kind of materials very powerful on a 4/5amp battery give it 10/10
allways wear goggles
Realy good easy to use powerfull mashine handy for small jobs
A great addition to our Ryobi collection!
Really good addition to our Ryobi collection! I really like the fact that the batteries can be used across the range. We have used for a variety of projects, from cutting fence panels to size with a wood blade to trimming hard to cut shapes out of our bathroom tiles. A very versatile tool to have indeed! One thing I would say is that due to the power needed for the tool, it is worth noting that it runs the battery down quicker than the others we have so I would recommend using it with the 5ah battery if possible.
Brilla
Ryobi power tools, are the best tools I ve ever used, I rate them as the same as dewalt, or bosch
This is second one I have had a very useful tool
Good tool had to replace worn out one that I had for years , can’t do without it so versatile, reliable as the rest of their tools that I have brought.
Great as a backup
Not as powerful as a corded tool, but good enough as a second tool with a wire wheel or cutting smaller/thinner metal. I use mine with generic 6ah batteries which run for ages.
Good tool!
Ryobi does it again !
Must have for the One+ collectio
Portability is the key
Really struggled with hacksaws to take apart an old large rusted fruit cage and as I have a selection of Ryobi tools and batteries decided to get this model. Just make sure you have more than one battery, the most powerful type, as you’ll get through them at a fair old rate. Also choose the best quality discs and you’ll get the most out of this tool. Be careful on seating the discs and always keep the locking tool with you as I found that the occasional one would work loose when cutting. Overall did the job I wanted it to do and would recommend if you had jobs to do away from a suitable power source
I have had a battery powered grinder before from another brand and it was pants. The lack of torque just meant it bogged down almost immediately making it useless in practice. Honestly I wasn’t going to bother buying another cordless grinder but when I saw this on offer – and being a user of Ryobi tools – I gave in and tried again.
First off I will say that I have loads of Ryobi stuff going back ten years. I started buying their tools when they first changed to the lime green colour because they were well priced and did the job. Clearly made to that lower price nevertheless they proved to be very robust and the batteries utterly superb. I have spend ten solid years renovating a house including digging out under it and putting on another floor using Ryobi tools with little care at all. So far none have broken despite the abuse. And one battery I bought eight years ago has just carked it despite it having been charged hundreds and hundreds of times. Damned impressive.
Since those first two drill/drivers I bought made with hard shiny plastic Ryobi have steadily pushed the quality upwards. My latest drills are easily as good as the trade stuff like DeWalt and Milwaukee. In fact Ryobi and Milwaukee are owned and made by the same Hong Kong company, Techtronic Industries in their own facilities. And of course they have different internal parts. Not…
Of course a couple of things to note with the increased quality. The weight has gone up as well as the price.
Anyway, this tool is super well made, has high quality materials in its case and is easy to hold given the handle design. The overmoulded rubber grips are very good indeed and the side handle can be mounted on either side for lefties or righties. It’s vibration isolating as well.
However I have a couple of things to note. Firstly my day job is a marine Chief Engineer and as such using metal working tools specifically grinders is a daily thing on a ship. Welders will also know this but the handle which is always supplied is never used by ‘professionals’ – ever. Not once in any shipyard or welding shop have I seen a small grinder with a handle fitted. Same on a ship. They are just annoying and get in the way.
The other thing is that the power switch is a ‘dead-man’ one. In other words you have to keep it depressed to keep the grinder going which, is a pain. If you are using a grinder in the perfect position as shown in the advertising bumph where it’s at bench height and you are pressing down then fine. However, these sized grinders are used for working in all sorts of positions and that means you might have to move your hands away from the switch. That’s why most grinders don’t have a dead man but instead a locked on power switch. This grinder being battery type is, one would have thought even more likely to be used for convenience of location thus the hold on switch even more irritating.
Bottom line is that if I’d known the switch could not be locked in place I’d probably not have bought it despite it’s other qualities.
Putting that aside in use this is excellent. It didn’t bog down at all and the battery I used 4Ahr lasted well and provided plenty of power.
It is a bit larger than a mains unit but is well balanced and the handle part being slimmer makes it easy to hold.
Overall this would have been a winner had it not been for the dead man switch.
Good value
Not the best I’ve battery angle grinner ever used but I’m impressed for the money many problem is slightly low ish on power but definitely will get there just a bit slower than more expensive one’s

Powerful, easy to use and quick to change discs.
Very powerful tool with good battery life (I’d get a 5Ah battery) and it’s easy to change discs. Get some thin, metal-cutting discs, some fatter grinding discs and a small buzzsaw disc for wood.
Easy to use
Easy to set up and use…. Ideal for cutting wheel clamps off with
What do you expec
1st off,this is a battery grinder,i dont expect it to work anywhere near as hard as a corded one so i treat it as such,great when i’m out on a job miles away from a power supply,it does go through battery juice but i dont mind if it saves me getting a hacksaw out.
Great cordless grinder.
Great grinder, I’m using the 5ah batteries and seems to last a while and has enough grunt to manage most things
Well balanced, great quality
My first ryobi one+ tool. Seems very good quality. Havent used it much yet but feels well balanced in the hands, stable, plenty of power, cant complain. Also got a drill which was free as a gift when buing a starter kit so pleased with that too.
Grea
Brilliant got on sale so even better great kit bought husband as a gift he loves i
great value with large battery
definitely worth the money with such a large battery. easy to use and quite powerful
Great tool
I use this power tool almost every day well worth the experience
I was attracted to this by one of the regular emails from Amazon which, if I’m honest, often get ignored.
Buying it as a set gives a very substantial saving over buying the component parts separately. If looking at alternatives make sure that they include a battery and charger, potentially 80 if you buy them separately. I like the concept of the 18V ONE + because, if travelling, you can share batteries between tools of the same range, giving flexibility and saving weight and space.
It seems to be a quality product, easy to use and with minimal vibration unlike some grinders whose vibrations make them unpleasant to use. While ear protection is recommended, it seems quieter than many others. The charger gives clear battery status and a reasonably short recharge time
For a cordless tool it has a decent endurance but the battery life is finite , as on all cordless tools, so my next purchase will be the 5Ah battery, although the price of a 5Ah battery is nearly as much as the complete set!
Works great, very happy
This tool probably paid for itself the first time I used it. As other reviews have mentioned, consider battery size if you’re buying a bare one, low capacity batteries are very limited in this tool, that’s why I bought the one with a 4Ah battery
works for me
good solid tool and good quality unit, battery life depends on the job but add few extra batteries like i have and you have back-up really pleased with this product.
Well priced great cordless grinde
I use this for work & at home , great little tool , good for cutting & trimming steel to size for the smaller jobs that need more precisio
I use these tools as a professional joiner / kitchen fitter they have never let me dow
Like 4ah battery ,charger ( compact) , bag and grinder for just over 100 The battery alone is 65plus good value for money wish they did more deal like this . I have a few ryobi tools the 4ah battery will run the fan all night .Two of the battery’s I have are more than 10 years old and still work
Excelle
Bought this to do some home diy and it’s Excellent.
Handy and convenie
Works well. Easy fast and convenient to use. .. no setting up and plugging in cables for what is maybe just a quick small job
Easy and versatile
Love this product, makes cutting and grinding more versatile..
Battery life can be an issue if you don’t use a 4 or 5ma battery..
Cable free
Having been used to a cable angle grinder, the only question I ask myself is why didn’t I get one before?
Great grinde
Great grinder, well pleased with this product, well built, easy to use
Easy to use grinde
This grinder is very easy to use and is very sturdy. It’s light when no battery attached.
Versatile cutter everyone should have
This is a good edition to the Ryobi +range and is a very useful cutting tool when you add the right blades, my only comment would be it needs a bit more speed, it labours a bit when you put pressure on the cutter. Also the tool supplied for changing blades isn’t very stable it’s a bit cheap and hard on the hands.
My 30 year old corded angle grinder has finally died, and having bought into the Ryobi System, thought I’d try the angle grinder.
It is a heavy piece of kit, and adding a 4ah battery makes it even heavier. It was noticably less able to cut rebar than my old B&D corded one, and given I don’t need cordless I decided to return it and get a cheaper corded one – in fact i could get two – one for grinding, one for cutting, for almost the same money.
A perfectly acceptable tool if you need cordless and have the Ryobi batteries already, but not quite the power ( and much heavier) than corded. If it’s your first battery tool, I would recommend having a look at Bosch/Makita etc before making a decisio
When you have the battery and grinder you have one powerful work tool from Ryobi all the bes
It’s a great work horse but you got to get the battery bigger the beter to accomplish any large job you may do
Ideal battery Grinder use a good battery.
I use good batteries and never had a problem with lasting out on job now added to my collection of Ryobi.
Little lack of power but might be because of small battery?
I’m using 1.3Ah battery ( all I have at the moment) and it did shut down cutting through the thin steel pipe couple of times (especially putting little strength to the grinder)- I’m not sure if it is some sort of safety feature, lack of power or simply too small Ah battery ( recommended battery for this tool is 4Ah ) Thought *Ah is related to how long battery last, but can be the factor of how much power grinder drains per cut? Not sure.. Feels solid tool tho, resting in the car boot, no more clamping down tickets for me 🙂 Just kidding ..
I have thr drill and the hoover, for years I wanted a battery grinder and I am not dissapointed, the small batteries dont last very long for prolonged grinding but the 4ah battery gives a considerable extention to battery life, however I have three batteries so battery life is not an issue,
This tool is just so handy for working out the back of a van going to customers and needing to cut siezed bolts without having to drag leads all over the place
Nice tool
Looks a good piece of kit not tried it yet as is a present will tell ye late
Easy to use
So easy to use no worries about cables getting in the way.
I was a bit skeptical that I really needed this tool, should I or shouldn’t I get one, but then I thought hey it’s Christmas. 🙂 This little angle grinder is best suited with the 5ah batteries which give it the full power it likes. With a 1 mm wide cutting disk on it, it cuts through rebar no problems and is also good with a sanding disk. One other use i get out of it is with a small TCT cutting blade it helps trim those thicker branches in the hedge. It obviously doesn’t have the RPMs of a mains angle grinder but in some ways that makes it more controllable and less aggressive, in any case I’ve been using it for nearly a year and have found it to be reliable and a handy tool to have.
5starsBriliant piece of kit.
Love this, great addition to my Ryobi one+ range, typical Ryobi quality
I like i
My wired angle grinder died and I already had a couple of Ryobi ONE+ products, so seeing that the reviews on this were good, I bought one. It seems just as powerful as my old Metabo wired grinder but has the convenience of no lead. I’m only a hobbyist, so battery charge life isn’t an issue for me. It lasts plenty long enough for my needs.
What's not to like?
This is a great tool! Very well made and easy to use. AND no cords!
Love i
Arrived the next day as it said.
My husband loved it .
eplaced similar grinder.
Replacement for an old workhorse that only gave up the ghost as it was dropped from a height onto a hard surface.
Solid grinde
Usual Ryobi build quality. Performs well using official 5ah battery. One niggle is would of liked the handle to store the disc release tool. I know it can be kept in bag but would have been a nice touch. Overall pleased with the purchase

Superb and powerful tool, should have bought one years ago.
I have several other Ryobi power tools and when my corded angle grinder finally landed in the recycling bin this seemed a natural choice as a replacement. Although this was a more expensive option than buying a corded replacement from the DIY store I have the 18+ batteries so decided to give it a go. Personally I find this better balanced and easier to use than a corded version, and can of course be used anywhere. The motor weight seems to be counter-balanced by the battery which works well for me; I’m using the larger 4ahr battery’s which give longer life but it’s early days and time will tell how this works out in the long term.

Great for the small to medium jobs only really limited by battery capacity
Love this, great addition to my Ryobi one+ range
Love this, great addition to my Ryobi one+ range, typical Ryobi quality, NB you need a decent sized battery, i used initially with a 1.5 battery I had and didn’t last long (cut about half a slab), bought a 5 battery and much better.

Present for hubby so I’m sure he will be pleased with the purchase
good for small jobs away from mains power source
Neat tool. I already have selection of Ryobi one plus tools & a couple of 2.5ah batteries. The grinder seems reasonably powerful, good for small jobs away from mains power source. I used it to cut through the tongue of a deadlock with thin disc coped well.
Great wire free grinde
Useful for remote no power areas good running time on 5ah battery too

very handy tool to have if you already have the batteries. Not what I’ll use for longer grinding jobs but quick fixes when I don’t want to run a power cord this is ideal.
Spot on tool, had lots of use out of it.
Great Tool, Price & spoy on.
It was as I expected, just the tool for the job, pleased i got one of these!!!!!!!!!
I’m new to Ryobi, but their kit appears to be well designed and well made. Comes with clear instructions, solid, easily recycled packaging and even a free grinding disc to get you started.
I used the 5ah battery, and was surprised at just how good (and handy) a cordless angle grider is. First job was to cut the tops of fire extinguishers which it did with ease – remember to clamp the material down though!
Would I buy more Ryobi kit? Certainly, if it’s as well designed and well made at the angle grinder.
Remember this unit comes without a battery! I can recommend the 5ah battery and charger ( Ryobi RB18L50 ONE+ 5.0 Ah Lithium Battery
Five Stars
works better than I expected very please but worth using the 5.0amp for bit more longevity
Handy and inexpensive grinder.
A good solid but light use anywhere angle grinder .Ideal for grinding and cutting metal and for cutting chases in masonry to receive lead flashing ( with the correct blade in !)
Very powerful tool for a battery powered item. Have used it in anger many times now and can’t fault it !!
I like the guard adjusting clamp
Enough power, feels stable, I like the guard adjusting clamp.

Another great tool from Ryobi
Not really used in anger yet – but good quality and not too heavy
Great tool ! obviously not quite as powerful as a corded model but very handy nontheless.
Great if you need to use it one handed as well.
Top tool
Top tool genuine germany made not the china made which i had before which only lasted 6months
I was apprehensive that an 18 volt battery could drive an Angle Grinder with any degree of stamina and endurance. The Ryobi R18AG-O 18v One plus fitted with an 18v 4.0 Ah Li-Ion thick pack battery soon removed any reservations I might have had on that score and I need not have worried.
The Ryobi performed like a dream. Metal cutting,Grinding & paint scraping with a wire brush, were absolutely no problem. I particularly like the Auxillary Side Handle which is attached to the Body of the Grinder in 3 alternative positions, namely 3 o`clock, 12 o`clock and 9 o`clock.. The safety guard is easily removed and replaced. Comes supplied with a wrench for removal/attaching discs/brushes etc. The overall length of the Angle Grinder, without a battery fitted, is 330mm/13″. Fitted with a 4.0Ah Battery, Auxillary Side Handle and a Standard 115mm Grinding Wheel, the unit weighs in at 5lb 14ozs (2660 grams)
I would recommend the 4.0 Ah Battery for its durability when using it with the Angle Grinder as opposed to batteries of lower capacities. When you consider that the motor in the Ryobi Angle Grinder delivers 7,500 RPM, the 4.0 Ah battery is the way to go with this particular Tool from the Ryobi range. Impressive.
Alan Metcalfe ( further down in the comments ) said ” NO POWER ” I do not know what trade he is in? , but he certainly does not know how much power is required to make a tool like this work . I will say this ” Do not expect fantastic results from a 1.3 or 1.5AH li-ion Battery , use a 4.0AH Battery and then comment , if you have a prolonged Job then Purchase 2 x 4.0AH Battery’s and make sure you have a Ryobi super Charger so you can charge quick .
Just a point of note , does anyone know of other Tool manufacturers that make a cordless Angle Grinder , I would like to compare.
Really pleased with the grinder. Nice and comfortable to hold and a great part of the Ryobi set. Nice 2 trigger action to prevent accidentally starting.
Five Stars
Very happy with item does what it says on the box.
Very useful piece of kit especially when you can share batteries with other Ryobi tools
ice piece of kit. bit heavy on battery, but that’s what the 4Ah battery is for.
Great product,would recommend a good supply of changed batteries for those larger jobs considering a higher capacity battery for myself
