DeWalt DWE402 Angle Grinder Review

Dwe402 is a quite attractive angle grinder. It is yellowing color, on which there is a DeWalt logo which is written with black ink. So it looks quite appealing.

Let me tell you it’s one of the powerful cut-off grinders which feature an amazing motor of 11 Amp. Motor has carbon brushes but the best part is, DWE 402 has oversized brushes. These big brushes provide 2 fold longer motor life than the previous model of DeWalt angle grinder.

Talking about the speed of its abrasive discs, so 11 amp motor produces 11,000 RPM speed. With the help of which you can do your job more precisely and efficiently.

Since DWE402 is a cut-off/grinder that is meant to cut different concrete and masonry so there should be some extra protection features for the internal component. For this purpose, there is an adjustable guard which is there on the top of the abrasive disk so that no stone, dirt or debris can enter inside the tool.

Dewalt DWE402 PriceYou must be thinking that the adjustable guard is not at all a differentiating feature. It’s there in every angle grinder. But what makes the guard of DWE 402 different from the other is its 360-degree rotation.

Yes, it features a mind-blowing One-Touch ™ guard that can be rotated to 360 degrees without using any specialized tool. You can adjust it in your required position without wasting your precious time.

For the protection of internal components of the DWE 402 angle grinder, it has an innovative Dust –Ejection system ™. This innovative system allows the air to enter into the angle grinder and ejects the harmful and harsh elements during the process.

Dust-Ejection system™ is further backed by a unique Airflow system, which allows the outside cool air to enter into the machine just to cool down the internal components.

This way it protects the angle grinder from damage and dust and hence your tool will gonna last forever.

What I don’t like about Dewalt DWE402 Angle Grinder:

Paddle on/off switch is basically meant for the comfort and convenience of the operator. But its paddle on/off switch is quite annoying, especially for those operators who use it daily and wear gloves to use it.

It becomes hard to operate the paddle switch using gloves.

In my opinion, a frequent user of DWE402 angle grinder becomes used to operating paddle switch and hence they should not feel irritating while operating it.
