I am very happy with the performance of this DeWalt angle grinder. The user manual leaves a lot to be desired, though. However, most of the set up and operation is common sense (at least I felt that way). I used it to strip paint from a house foundation, and it worked very well. I want to emphasize that it's critical that the user wear appropriate safety gear: eye protection (safety googles) and proper respiratory protection (use a face mask that matches the possible particulate contamination that will become airborne and surrounds the user). Very happy to include this angle grinder in my DIY toolset. 4.75+ stars.

I’m partial to dewalt tools so my opinion is biased. That being said it has worked great for my projects. Changing the wheels is easy and it comes in a nice case. You won’t be disappointed in this tool.

The good. More power than you need. The consumables can only handle so much. It is light weight/power balanced and smooth, after a break in period. Running a grinder is never "fun" so having one that can make the least work of it is important.

This Dewalt DWE402 replaces a cheap Chinese 4" grinder that is about to die on me, but you cannot compare these two! This is a pretty amazing tool for the price (often well under $100). Buy it even if you don't think you need it! You won't be disappointed. It's a bit more bulky than a 4" grinder, and it also has a tremendous starting torque which tends to twist it in your hands when you first hit the trigger. Also, the trigger lock is a bit clumsy with gloves. So I dropped it one star in Maneuverability. But having too much torque is hardly a "flaw".

This is my second Dewalt grinder, first one lasted for 10 years. Having a steel sailboat, I put my grinder to heavy use, cutting and grinding steel plates...the main advantage of the new grinder is the design change of replacing grinding wheels/cutting disks with an Allen wrench instead of wrench. Moving the guard doesn't require any tool and the grinder is much more powerful. Been using for 9 months and no problem whatsoever.
