Great Tool for the Home or Business!
I purchased this Dewalt Grinder to assist with sharpening my riding mower blades. I have a lot of Dewalt cordless equipment so I wanted to make good use of the batteries I have already.
First, I will say this grinder has some serious torque. Just by activating the trigger you feel the tool twist in your hand from the torque.
Pros:
Great Power
Ease of accessing tight spots
Ease of changing disc
Grinder guard is easily adjusted without tools
3 year limited warranty
Comes with battery and charger(starter kit)
5 inch grinding wheel included
8000 rpm motor
Compatible with Dewalt batteries
Cons:
Weight of 6 pounds
I used this grinder to sharpen my mower blades and as you can see it did a great job. It was easy to control and the brake for the disc slowed the grinder pad soon after I released the trigger. This will prevent unwanted damage and injury. This is a tool you didn't know you needed, until you don't have it. I have attached photos of the mower blades. This tool is a beast and has multiple uses! If you find this review helpful, I would appreciate giving it a like and helpful check!

By far the worst set up with this battery
I am not sure why this combo is being offered, the battery is horrible with this grinder, it dies SO quickly. You will probably need several 5 AH or higher to make it usable on an actual project.

When my son was young I had a basketball hop installed in our yard. The installer not only cemented the post into the ground he poured cement into the post. I wanted to remove it but couldn't decide which power tool to purchase for the project. I originally decided on a reciprocating saw but decided it wouldn't cut the post as close to the ground as this DeWALT Grinder. This tool did the job perfectly. However, the grinding disc supplied with the tool wasn't quite suitable to the job so I purchased a Rigid Metal Cutting Diamond Blade. This combination was perfect for the project and did exactly what I wanted. It not only cut through the steel but the cement as well. I would highly recommend this tool as well as DeWALT tools as well!

works as intended- slapped the cup grinder on this baby and the mortar magically disappeared...even taking with it the dust after putting on the dust shroud. Simple, easy to use and put together, easy to hold and if you already have a couple 20v batteries this is a great value addition to use with those batteries.
