    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…

    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…

    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.

    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 decision

    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.
