Beast of a die grinder
This is a beast and will handle the toughest jobs. It has 4 speeds (10k to 24k rpm) and plenty of power. I like that the collet has a 2 stage lock to get the bit out. Its an awesome tool!

Variable-Speed, Safety-Trigger, Long Lasting
This little handheld die grinder is the replacement tool you have been looking for to work on your automotive, metal, stripping material needs. This variable speed grinder with a 1/4 inch bit opening has enough power and speed to tear through build up and small enough to fit into tight spaces where pneumatic tools and hoses would be difficult to get through. Being one of the Ryobi ONE+ tools there are various battery sizes which can be used with this tool to make it more lightweight, longer lasting and even anytime ready. Love the smaller size (smaller than impact driver or drill tools) and the spring-loaded safety ensures that there is no accidental activation. The oversized leaf spring trigger makes it easy to keep activated as you move around the work area and doesn't tire your hand out from excessive tension to keep the trigger activated. While it rotates in only one direction this is still a tool that can be used inside, under and around areas that have previously been inaccessible, The bright LED light is positioned to still illuminate the work area when gripped and put no load on the battery. Well worth a try and a must have addition for high speed grinding jobs.

Balanced Cordless Die Grinder
Recently, I received an email, alerting me that a Home Depot "Seeds" campaign was open. I opened the email and went to the 'Dashboard" page and started to go through the latest list of items available. I selected one premium item and was told that I was allowed more items for "Seeds" selection. I went through page after page until I saw a Ryobi 18V Right Angle Die Grinder. I selected it because I already had the proper batteries, since I already have other Ryobi tools in my garage. When the tool arrived, it was a lot lighter than I expected and extremely comfortable in my hand. I had charged batteries available, so I plugged one in. I then put a generic mounted stone in the quill, tightened it up and engaged the finger safety switch, as expected, and pulled the trigger. It was exceptionally smooth, deliberate, and variable. I really liked the feel. The grinder was on setting number one, as indicated by the lighted switch position, positioned on the lower front of the tool. Each press of the adjacent button increased the speed of the tool. The number one setting was good for 10K, two was good for 15K, three was good for 20K and four was good for 22K. Also engaging the trigger, lit an LED attached work light, focused on the area immediately in front of the working tool. A nice arrangement and very practical for one that has worked on die grinding in industry. Most of the time, it meant using an industrial light that was too big and bright to do any good. This was perfect. The upper settings are primarily for better balanced mounted stones, rated appropriately. Pay attention to the warning label on the stone. Also Included in the package was a quill wrench to lock the stone in the spindle. Having used my share of industrial tools, this is a great tool, with all the functionality of the more expensive industrial variety with more features at less cost. Highly recommended by me.

Another Great Ryobi 18V One+ Tool
The brushless motor is smooth and not very loud. There are 4 speed settings depending on the die accessory you are using. Speed 1:0-10,000 RPM, Speed 2: 0-15,000 RPM, Speed 3: 0-20,000 RPM, Speed 4: 0-22,000 RPM. The tool accepts standard universal 1/4" shank dies and bits with a max diameter of 2". The collet nut is 11/16" in size and comes with a wrench, there is a lock button to hold the spindle shaft steady for bit removal and also indents in the shaft if not using the lock button. The paddle trigger has a smooth, linear operation and has an integrated safety switch which can be operated one handed. Pressing the switch also turns on a LED work light. The name of this tool can be confusing, this is a die grinder, not an angle grinder, it is just that the handle is an ergonomic pistol grip style at 90 degrees. The tool comes with a 3 year limited warranty. This works with the same Ryobi 18 volt one+ batteries as my other tools regardless of amp hour, battery composition or HP style.

Nice Die Grinder
This is a very nice tool that works very well. It is fairly light weight for a battery-operated tool about 1 lb 9 oz for just the tool and 2 lb 9 oz for tool and a 24 Wh Ryobi battery. It has 4 speed setting modes that you control via the push button on the base of the tool. You can also vary the speed with the trigger. The four settings are spaced about right for anything you would want to do and it is nice to be able to control the speed as you are working with the trigger. It has good power, about on par with my good quality air die grinder, the down side is that it is heavier and bigger so it won’t fit in as tight of a spot. It is very quiet, not near as loud as the air operated one is. The trigger could be a little smoother when trying to control the speed, not bad just not perfect. The collet works nice and has a good feature that with you go to change the accessory you loosen the nut a little until the nut is loose then go a little more and it will push the accessory out of the collet. A wrench is supplied with the tool, but it would be nice to have a place on the tool to store it. I also wish that it had an 1/8” collet. The handle feels good and the balance is nice. It has a work light in the base which does a pretty fair job of lighting up what you need it to, but might be better to have one mounted at the top close to the collet. All in all a really nice tool.

Another great ryobi tool
RYOBI ONE+ HP 18V Brushless Cordless Compact 1/4 in. Right Angle Die Grinder (Tool Only). This is a great tool. I really like the four speed selectable speeds. The trigger has a lock so you can't accidently bump it. It has plenty of power for small jobs. I have used it with a deburring bit and a scotch brite type pad to clean gasket surfaces. Im really happy with this tool.

Another Great Tool
This is another great tool by Ryobi. The LED is very bright and changing the speeds is very easy to see and use. The trigger has a nice feel and reminds me of my other Compressed Air units. It has a nice weight to it and balance. Like all my Ryobi products it feels like it will last a long time and be another great tool to add to my collection. Thanks

Great Title angle grinder !!!
This is a very nice angle grinder with four speeds a work light and a push button shaft lock for changing out grinding stones. Only thing I found wrong with this grinder is a storage space for the wrench. I like the four speed settings for delicate work and fourth speed for heavy grinding. This is a great addition to the 18+ family. This is lightweight and portable to take to any job site.

Good portable grinder!
We got the grinder to add to the other Ryobi 18 volt tools that I have. The grinder is lightweight and easy to use. The 4 speed settings are a good feature, but I use the fastest speed for most of all of my uses. The constant on feature is unique and it took a little time to get use to, but I like it now. Nice little grinder I got for my around the house use. I like it.
