Battery powered angle grinder
I already have a corded angle grinder but been considering a battery powered one for ages. This Royobi grinder Popped up on Amazon for less than £70 and I took the plunge. Used it on the garden to cut some 50mm thick concrete path edgings with a diamond blade I had. Performed fine but don’t try to force it really hard or may stall out. That said it did the job, just take it steady when cutting and will cut without issue.Also cut some of the metal edging pins reckon 2mm thick mild steel. Zipped through it. Battery life I had a 5A battery in it and all was fine. I ran out of things to cut before the battery did. Overall I am very happy with it. Will make those jobs where getting the corded grinder and an extension lead out is required a rare event. It’s a lot bigger than my corded but that doesn’t bother me as the heavier and chunkier a tool feels the better. Would say Usual Royobi in terms of the plastic and overall quality. My Final Thoughts, would I buy it again, a definite yes!

Better than my corded one
Nice litter grinder bit heavier than my 240v one, with a 5 amp battery, and you do need a big battery as it eats power for fun. I bought this for one job, cutting down a breeze block wall at the top of my garden, it would not disassemble with a sledgehammer so I got a diamond blade and cut the morter all was well after that. I would have like to have seen a few cutting discs al well as the one grinding disc

Great - One Niggle
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.

Impressive Grinder
I had the older model of the grinder and it was getting a little old and weak. As I have a lot of the Ryobi one+ system it was a simple choice and so much cheaper than the more regarded brands. Anyway only used it a couple of times so far but absolutely impressed with it. I use the 4amp batteries and it lasts more than long enough for the small jobs an electrician does. I cut a couple of small plates out of 4mm steel today and it was a breeze Time will tell how long it lasts and if the performance keeps up but so far really pleased and very surprised how much better than the old model it actually is. The only thing I would criticise it for is that it no longer comes with the key built into the handle for removing the disc's. I thought that was a really neat idea on the old model. Luckily though I still have mine off the old grinder and it fits on the new one. For small jobs having a battery grinder can save so much hassle. I had to take some lights down using a cherry picker once and the bolts were seized on my battery grinder might the job simple so well worth having one . Dave

Ich nutze den Ryobi R18AG-0 jetzt seit einiger Zeit für verschiedene Arbeiten rund ums Haus und bin absolut zufrieden. Trotz Akkubetrieb hat der Winkelschleifer überraschend viel Power – egal ob beim Trennen von Metallrohren, Entrosten oder Schleifen von Steinen, er arbeitet zuverlässig und sauber. Das Gerät liegt sehr gut in der Hand, ist ausbalanciert und durch das kompakte Design auch in engen Bereichen gut einsetzbar. Besonders praktisch finde ich, dass man den Handgriff in drei Positionen montieren kann – perfekt für Rechts- und Linkshänder. Der Scheibenwechsel funktioniert dank der Spindelarretierung schnell und unkompliziert, und der verstellbare Schutz lässt sich ohne Werkzeug anpassen. Auch die Laufzeit ist mit einem 4,0 Ah-Akku ordentlich – für längere Arbeiten reicht ein Ersatzakku völlig aus. Ich nutze bereits mehrere Geräte aus dem Ryobi One+ System, und auch hier zeigt sich wieder, wie praktisch es ist, denselben Akku für alles zu verwenden. Fazit: Ein leistungsstarker, handlicher und zuverlässiger Akku-Winkelschleifer, perfekt für Heimwerker und ambitionierte Bastler. Klare Kaufempfehlung! 🔧⚡️
