Great Cordless Angle Grinder!
Many of my tools were from my dad and have seen better days. I've been upgrading as I can so it was nice to go to a cordless angle grinder from the old corded one that is 25+ years old. Although there is something to say about how stuff was built back then, the cordless feature is really what makes the difference. This Ridgid grinder goes very well with several of my other 18V Ridgid tools. The battery slides onto the bottom of the shaft. The included handle can be screwed onto either the right or left side depending on your preference and job requirements. It seems very balanced and has a good feel in your hands. Performance is great. The brushless motor seems ultra capable with plenty of power. The protective guard around the cutting disc is easily rotated to whatever location fits your needs. Very simple to swap out the cutting discs. The one con I can think of is the on/off switch. It feels a little flimsy and does take some getting used to. But it's not a deal breaker.

Excellent addition to your 18V RIDGID tool chest
RIDGID R86047B 18V Brushless 4-½ Inch Angle Grinder If your invested in the Ridgid 18-volt platform you now have your own winner. This angle grinder, in the paddle switch configuration, does exactly what you need when it comes to grinding, sanding, or polishing your project. The angle grinder is equipped with the tool free spindle nut, this allows you to change the tools disc's just as you would expect, without the need of the ubiquitous spindle wrench. The Ridgid 18-volt angle grinder works and preforms extremely well with any of the Ridgid batteries, from the 3-amp hour up to the 6-amp hour battery. I would dare say this angle grinder is a home run for Ridgid Tools.

Plenty of power with tool-free wheel changes and guard adjustments
As soon as I picked up the grinder, I could tell it is well built. Solid construction, but not overly heavy or awkward to hold. After attaching the side handle to either side of the spindle head, the grinder feels balanced in my hands. Both the side handle and body of the grinder have a gray, rubberized texture surface to provide a secure grip. The grinder has a paddle switch with a small lock-out switch that I can push forward with my middle finger while my hand is wrapped around the handle/tool body. The paddle switch is not a variable speed switch. The grinder doesn’t require any tools for installing or removing the various wheels and discs used with this grinder. There is a spindle lock button and a clamp nut that is tightened by hand. The wheel guard can be rotated or removed using the guard lever. The grinder uses only Type 27 wheels and discs with a 5/8 in. arbor. As for any kind of maintenance, there is a vent cover at the base of the grinder body/handle that snaps off and can be rinsed with water or cleaned with compressed air. I really like this grinder, I don’t have to apply too much pressure, the weight of the tool seems to be enough downward pressure. Applying too much pressure will trip the grinder’s over load protection feature and cause the grinder to shut off. RIDGID recommends using this grinder for grinding, sanding, and polishing. The manual cautions you from using this grinder with a cut-off wheel or using the grinder without the wheel guard installed.

Good Grinder
The Ridgid angle grinder works pretty good. This one has a brushless motor that run strong. I haven’t had any problems with it bogging down or cutting out, when pressure is put on. So I am happy with that. I like the wheel lock down system, since no tool is required to change wheels. It has a paddle switch that is easy to work. Also, the guard is easy to adjust. The extra handle only can be used on the left or right. It would be nice to be able to mount it on the top side as well. Overall it works great for me.

Great Liteweight powerful angle grinder
I started using the Rigid 18 volt Brushless, Battery powered 4-1/2-inch angle grinder last week and I was surprised at the power it produced, no job was too big for this tool. The Rigid angle grinder made short work of sharpening the blades on the six-foot shredder and the light weight is very nice compared to my plug-in grinder, no need to go back to the house to touch up the blades. My rock cutting digging bar needed a touch up and that only took a minute without going back to the house for power, so this tool is going to be a real step saving and time saving grinder. The next day I did some fence work and pulled out a five-foot post with the concrete still on it so I grabbed the grinder and sliced a slit down one side and when I hit the post it just fell off the end, now I can reuse the post without making a bigger hole. The Rigid angle grinder is going to be a real nice addition to my toolbox.

Paddle switch angle grinder sucks
Very inconvenient to have to press the small switch and at the same time press the paddle lever to use, if either one is release the whole thing shut off, big hassle to press both the same time while trying to work.

Lots of power & elEasy to Use
This 18 volt battery powered grinder includes a 4” grinding disc, and thread in in side handle. It has plenty of power with an 18 volt battery, which is not included with this tool. The tool is well balanced in the hand and is easy to hold while using. All Rigid tools, including this one, have a lifetime service agreement, as do the batteries which can be purchased separately.

You can't go wrong with Ridgid
I chose Ridgid 18V Brushless Cordless Paddle Switch Angle Grinder to use on occasion to sharpen blades and cut tile. This unit is packed with power using a 18V Ridgid battery. I like the feel of this grinder, it's comfortable and I am able to get a solid grip on the tool. It gives me complete control over my project. It has an overload protection LED light that flashes if the motor is nearing overload. It's very easy to reposition the guard. The paddle switch is in a comfortable location. When you release the paddle switch, the break mechanism stops very quickly. The grinder feels well balanced. The handle can be attached on either side. A real plus is no tools are needed to adjust the guard or change accessories. Comes without battery, but uses the Ridgid 18v interchangeable battery which builds brand loyalty. You will receive the grinder, grinding wheel, guard, side handle and manual. I found it to perform well. As always Ridgid has exceeded my expectations

Very Nice design
I really like this design it is light easy to handle with one hand and two if you need too. I like the way it feels in the hand I had no problem using it to cut a peice of metal with one hand and taking a picture with the other hand. Aside from easy to handle I like the side handle stright out and you can put it on eather side for ease of use. Then I seen the screen on the back of the handle to help keep out dust from the work you are doing. I found I was able to rotate the guard almost 260 deg. and that was very easy with the quick spring button on the guard it also made for easy removal if you need to. Then the no tool changing of the blades or wheels is just outstanding very easy and you don't overtighten the blade this way. I was able to change from a grinding wheel to a cutting wheel in less than a minuet. For sure a 5 star tool
