Good overall, would recommend. Great for pipeline use
The guard is huge, lock button is difficult to use with gloves on. But the kick back brake works very good, the grinder is light weight. Very comfortable to use.

Awesomeness light weight works great
This is the best 7” on the market.Light easy to maneuver, thought was definitely put into the weight and balance. Power is there. I finish a lot of metal and it keeps up with the work load.

Not worth purchasing!!
These grinders are not worth buying. I purchased 2 of them and less than 2 weeks after purchasing they are worthless. They overheat and shut off within minutes of beginning use.

Good overall grinder
Works great for using the 7” wire/grinding wheels. Have had no problems to date. I run it off my Lincoln Vantage 400 welding machine. Only 1 smallhang up: 1 of these grinders plugged into my 3 way extension cord to the machine is fine. A second grinder like this one will kick the machine into high idle, probably because of the green light illuminating from the grinders. At least that’s what I figure at this point.

Best damn corded grinder
Best damn corded grinder I have ever used. I has a completely different sound while using, it's more like a scream. And the feature I love most about this grinder, besides the power and slim body design, is the moment you let off the trigger the wheel ALMOST instantly stops. Really good for people like me that put grinders down while the wheel is still slowing down; then reach over for something and get cut.

Not for pipeline
This may be okay every once and a while around the house but it will not last on pipeline/everyday use. Really sad for the amount they charge for them.

Not worth the cost
Only had for 8months and had issues. Dewalt warranty failed to fix issue.
