This is like needing to haul a bunch of large, heavy rocks out of a quarry, showing up in a sub-compact sedan.... Then being genuinely surprised that the vehicle does a terrible job of hauling away the rocks. It was never meant for that job. The Ryobi *angle* grinder was never meant for _that_ job.
Bit of a misleading title. I was expecting you to trash it for being an overall bad tool, and/or under powered. This more of an issue with a specific use case. It's a valid point, but the tool is till not bad for the price (and a much more powerful HP Brushless version is available for those needing more oomph), which you yourself admitted. Comes across as click bait honestly.
I have the Ryobi P4221 , I think same as yours. I rotated the metal gear housing 180° . It's secured by 4 screws. So now the battery sticks out from the back, as it should have been from the start..
"i can only grind at an angle" You understand it's called an angle grinder, yes? Part of the reason for that design might be that this isn't a powerful tool, and that grinding with the whole face of the tool would show the lack of power of the tool
Strangely enough Ryobi chose to eliminate a critical feature that's found in their previous model of battery angle grinders, the P420 (which I own). It allows you to rotate the battery out of the way to handle those flush grinding jobs you're trying to do on cement. What a shame that they eliminated that feature.
Serious? How insane for an otherwise savvy company. So.... Now it looks like I will be buying a ridgid grinder. To add to my rigid framing nailer. Which I bought because ryobi didnt sell one. This is izzackly how you force a customer into another brand. So stupid. How does this get past R n D? I was just experiencing the same frustration and decided to look it up and see if anyone else was having this problem. I guess I'm just going to get a corded one for this job. And I know that Ryobi and rigid are both made by ITC corporation but ... My point is still valid and I'm still pissed and I still want to whine about it so there!!! I have a ton of Ryobi tools and normally I love Ryobi (not the old navy blue tools but starting with the green ones}. The prices have been phenomenal and the product is very solid middle of the road if you watch any project farm videos and in some cases better than average for a lot less money. True, that is changing these days, but still a pretty solid value. So F U ryobi for releasing stupid shite.
@@coppulor6500Ryobi, Ridgid, and Milwaukee are all owned by the same parent company TTI. So you spending more money on Ridgid instead of Ryobi is actually great for them. It's exactly what they want lol.
I have a Makita angle grinder to power carve my wood bowls. I'm going to buy the Ryobi to use strictly for finish sanding. I'm sure it will work great for that. But seriously don't use that little Ryobi for big grinder work. There are lots of options and the Ryobi was not the right one for that particular job.
Tim from Canada hey buddy I have 18 V tools to I have Milwaukee M 18 Milwaukee, M 12 and Ryobi. This makes me a tool expert too, but the only thing is I do not have a channel.
For that type of job. You need a corded 7" grinder with an arrow head diamond blade with at least 10-12 amps of power.You will be out all day with that battery powered and 4.5" blade.
He's inexperienced but learning the hard way he didn't get the right tool for the job it doesn't mean the tool is bad. You don't wear cowboy boots to play basketball it doesn't mean the boots are no good.
"95% of the time I love these tools but because this one random time I found this one specific tool to be slightly inconvenient for the random job I wanted to use it for, now I'm gonna completely ignore all that and instead I'm gonna shit on the entire brand and use the statement DO NOT BUY! in my video thumbnail hoping to dissuade others from buying a Ryobi." Tell me you voted for Hillary without telling me you voted for Hillary.
Tim from Canada because Ryobi is a DIY handyman tool platform. It is not a professional grade tool so people should not classify this as professional. This is handyman to I would classify Ryobi. In the same category. As Black & Decker. And Black & Decker is the lowest form of tool base you can buy. Until Ryobi come along, and now Ryobi is under. Black & Decker.
4:54 Also, you are using wrong cartridges on your respirator. For dust you just need P100 filters, which are much cheaper than activated charcoal ones you are using.
@@MinhvuLy depending how long you been using these cartridges, they may or may not still be good. Usually these cartridges are good for about 90 minutes, but it depends on contamination level in the air. Spray some cologne and if you can't smell it through the cartridges they still have some life left in them.
I STILL DID IT WITH THIS 1 BUT YOU HAVE TO UNSCREW THE HEAD AND FLIP IT AROUND IT CAN ONLY DO A FLIP AND TO LEFT OR RIGHT ANGLE THE TRIGGER WILL BE AT THE TOP AND THE SAFETY WILL BE AT THE BOTTOM I KIND OF LIKE IT LIKE THIS I HACKED MINE WHEN THIS MODEL FIRST CAME OUT CAUSE I HAD THE BLUE 1 THAT ALLOWED YOU TO DO IT. GOODNESS BE WITH YOU
They all made by TTi including Milwaukee.Ridgid owned by another company and tti is contracted to make them. Still doesn't make the tools created equal.
I have a DeWalt cordless grinder, not brushless though and this grinder just eats up battery power. I have an adapter where I can use my Makita 5ah batteries with this DeWalt tool and even those batteries run out of power in no time. I'm thinking that all cordless grinders have this issue, I don't know about the brushless ones because I don't own one .
I just bought a 18V Ryobi grinder and two 16V 4h batteries plus charger for $99 on a promotion deal. It works great for my application thus far. Interestingly enough, Techtronic Industries is the parent company of Ryobi, Ridges and Milwaukee 😄
Face it, this was simply the wrong tool for a specific task. That doesn't make it a bad tool. Your thumbnail needs to be changed. It states "Do not buy". But in the clip you say its just fine for 90% of the tasks. It would be easy to make the case that it is 100% fit for task for people that have no use for a concrete grinder. PS Having recently had to grind down some concrete with a similar disk I would advise anyone not to use a cordless grinder of any description for the task. It is a slow, arduous process, which I am sure would chew through the batteries in no time. This is definitely a task for a corded grinder.
Wow.... DO NOT BUY....???? That's your thumbnail. Do realize the angle grinder was not created for the main purpose of grinding down cement? I would have to say that the majority of people that buy angle grinders are using them in a different manner that the battery is not going to be an issue. It sucks that it doesn't work out for your needs but to tell people not to buy it because of that reason is not even reasonable. A flaw to some but highly unlikely to be noticed by most. I use angle grinders everyday in multiple situations and I can say there would be very few jobs where that issue would arrive. The grinder is almost always elevated away from a flat surface.
I recommend a corded angle grinder or if you use a cordless, then get a big 9AH battery Milwakee or Rigid, don't buy Ryobi cordless. Concrete grinding is very energy intensive and drain the battery quickly.
@@MinhvuLy thanks for the tip! I’ll probably try the Ryobi corded grinder since it’s cheaper. I only have one job I need to complete so I opted to buy instead of rent because the cost was basically the same.
I had that issue when mixing concrete with my power drill and I think it just uses SO much power (I could only mix 4 buckets on each battery). So my guess was that it overheat or the battery just chugged reallllllly hard.
No offense to you but as someone who hasn't been working with tools long I know when it says angle in the description it means just that. Also corded is always better especially if you don't have multiple batteries. 🤷🏽♀️
I don’t think it’s a huge issue but it would be better to get a corded maybe if the grinder has a bevel head and lock it place then it would be flat but I don’t think it’s a bad issue but if someone wants it to be level then get a grinder that is level to the wall or floor you can’t tell when you buy it but I don’t think it’s an issue that should not be a reason to buy unless you want a perfect flat concrete wall and that is fine depending what people want it for.
Pretty sure the guard on it, it lays flat on guard. You really need the guard on there anyway for safety which would account for a slight angle. One wouldn't hold diamond blade flat while griding surface since guard needs to be in place for safety.
I was actually considering this model for this exact purpose.. but I wanted to do my homework before buying. I figured the battery position was going to be an issue. Took you a while to get to the point, but really appreciate this insight. Thanks.
DUDE! I have to level my concrete floor and I was looking at surface grinders thinking they were different from angle grinders. Nope. OK so I have ryobi, cut some poles with it (since its at an angle). So I've been WRACKING my brain trying to figure out how it could do a surface on the floor BECAUSE of that damn battery pack! So now it makes sense...YOU CANT?! I'm looking at the dewalt surface dustless one now.... Sigh! Well, at least I can cut poles at an.......angle
Thanks for taking the time to share assessment of the Ryobi grinder. And kudos for offering up alternatives. You just saved me the time, effort & disappointment of buying this tool to only have to turn around and return it. Very helpful video.
You are using the wrong tools for that job, guy o to a tool rental and rent a damm jackhammer and floor polisher. Retired from 45 years of construction and fabrication
Before you buy any tool, first check Project Farm channel. I tend to buy Ryobi for non commercial and Festool for fine work except for the angle grinder.
You prove that just because you can BUY all those tools, you don't amazingly acquire the skill to USE them. If you're trying to grind concrete with a $50 battery powered 4.5" ANGLE grinder, the problem isn't the tool - it's the "tool" who's using it. Ryobi's previous model allowed you to rotate the battery out of the way. They quickly discovered that "tools" like you were using it to do things no reasonable person would attempt to do - just like you are! They decided to discontinue the feature rather than deal with people doing exactly what you were trying to do! Ryobi makes a VERY affordable 10" 6500 RPM that has TEN amps and is more appropriate for what you want to do. It uses a CORD that plugs into the WALL. Deal with it! Corded tools do BIG jobs. Battery tools do LITTLE jobs. A professional mason uses even BIGGER tools for what you're attempting. The minimum tool (that Ryobi I mentioned) costs a fraction of what you spent on just ONE of those high-end batteries you're so proud of, and actually WORK. Even if you COULD move that battery, you'd chew through DOZENS of those little 4 1/2" grinding disks and maybe burn up the grinder's motor grinding down uneven concrete walkways. At least the home corded version uses larger, thicker and more appropriate discs. To be honest, if your walkway is of any real size, go RENT a big professional grinder. They have places that do that! What's funny is that you call yourself a "power tool aficionado" and spent almost half the video trying to impress us with that little shop (really dude? Have you ever seen a real shop?) and my first thought was "Where are all the big-boy tools? Grown-up kind? There's not even a miter saw, a table saw, a drill press, hell I didn't even see a bench vise (although you moved about quickly). Hell, a radial arm saw would likely kill you. You have the space for far better. The first lesson in ANY tools - use the RIGHT TOOL FOR THE JOB. You AREN'T. BTW those really expensive 9 AH batteries you paid $100 each for? They're for CONTRACTORS who need a tool that runs all day without worrying about finding a plug for recharging - often where they work, there isn't one. These guys just want to carry one, maybe 2 batteries for the whole day. YOU DON'T DO THAT. You work at home where there are a dozen more batteries in the shed! They don't make the tool run ANY better! They just make it run longer. You don't NEED that. YOU WASTED $200 FOR NO REASON. Just my opinion.
On many angle grinders, you can just rotate the head by removing the screws, rotating the head, then reinstalling the screws. Here's another video of a Ryobi angle grinder on concrete. ruclips.net/video/lWOTx-WwDV4/видео.html
Your title of, DO NOT BUY is a bit misleading! Just because it won’t do the one job that you bought it for. This is no reason not to buy it but perhaps you should of done your homework on the product before buying. Maybe not so much of an aficionado after all ?
First off, ryobi is not a pro tool brand. I’m a welder and I needed a grinder to get by, so I went with ryobi, one week of grinding frames for five days later, the damn thing blows out on me. Rant over, the damn thing is called an ANGLE grinder, not a flat grinder
Lol! So you buy a battery machines for doing a job of a 220v, you guys need to know what you need for your jobs, is not the machine is bad, its you dont know what you need for a type a job like that, simple like that
An angle grinder...ANY angle grinder, especially a battery operated grinder, is not the proper tool for grinding down a slab of cement that large. A concrete floor grinder or multi surface grinder should be used instead.
Get a tool that will work for concrete Ryobi is or any of the other ones you have not made for concrete just because you own a bunch of tools does not make you to know what your talking about
Entirely wrong tool and wrong approach - that was your problem, NOT the angle grinder. Think about it this way: if you HIRED a PROFESSIONAL to do this job: WHAT TOOL WOULD THEY USE???? Big hint - NOT a angle grinder. I would take this misleading video down. You seem like a good dude. Next time go talk to the guys at the contractor's desk or the rental desk and ask them if they have something to help you do ______.
Thumbs down for click bait. Which is too bad because you had a good point about it not being good for that particular application. How ‘bout just honest titles/thumbnail next time 🤷🏻♂️

Here's a crazy thought: Buy an extension cord and a real grinder?
Do you ever have an issue with your ryobi grinder overheating or battery cutting out? I am new to this tool and I can’t tell what’s going on with it.
No. I have not had that issue yet. *fingers crossed. I would suggest upgrading to at least a 4ah battery
I had that issue when mixing concrete with my power drill and I think it just uses SO much power (I could only mix 4 buckets on each battery). So my guess was that it overheat or the battery just chugged reallllllly hard.
You can disassembly top and rotate it angle 90 / 180 degree... brushless only 180 and more job in disassembly...
Did not know you could do that
I don't think cordless tools are for big commercial jobs...

First off, ryobi is not a pro tool brand. I’m a welder and I needed a grinder to get by, so I went with ryobi, one week of grinding frames for five days later, the damn thing blows out on me. Rant over, the damn thing is called an ANGLE grinder, not a flat grinder
Get a corded grinder and a 100ft extension cord. It’s cheaper and better than the 9ah batteries.
It's a angle grinder,all the gear yet no idea
Lol! So you buy a battery machines for doing a job of a 220v, you guys need to know what you need for your jobs, is not the machine is bad, its you dont know what you need for a type a job like that, simple like that
Biết tiếng việt ko anh?
Yes
It's a shame that the Ryobi engineers got that wrong.
I have a Ryobi P421. It's fine for what it is: a $30 18 volt grinder. He's using the wrong tool for the job.
Well 1. That's the brushed piece of shit grinder and 2. Smallest grinder I'd use for concrete grinding is a 60v dewalt.
If you want an angle grinder to last more then 6 minutes stick with a corded grinder!
An angle grinder...ANY angle grinder, especially a battery operated grinder, is not the proper tool for grinding down a slab of cement that large. A concrete floor grinder or multi surface grinder should be used instead.
god damn i am having the exact trouble.. u sir is a genius
Why it’s called a angle grinder lol
Thanks for your review. I nearly bought a Ryobi grinder but won't now.
I love Ryobi tools but the angle grinder needs modification.
Get a tool that will work for concrete Ryobi is or any of the other ones you have not made for concrete just because you own a bunch of tools does not make you to know what your talking about
just take it to a machine shop and ask them to turn you a spacer. Problem solved.
Entirely wrong tool and wrong approach - that was your problem, NOT the angle grinder.
Think about it this way: if you HIRED a PROFESSIONAL to do this job: WHAT TOOL WOULD THEY USE????
Big hint - NOT a angle grinder.
I would take this misleading video down. You seem like a good dude. Next time go talk to the guys at the contractor's desk or the rental desk and ask them if they have something to help you do ______.
Thumbs down for click bait. Which is too bad because you had a good point about it not being good for that particular application. How ‘bout just honest titles/thumbnail next time 🤷🏻♂️
Yeah. You are just using the wrong tool for the job.
Pretty poor review. Waisted time showing off your other Ryobi tools, then a review of something the tool is not really made for!
It’s a cheap Grinder
Simple as that
Wrong tool for the job. Your fault.
Get a better disk
Do not watch this video is a much better title
Ryobi chews a$$!
Wtf it's not designed that bud
