Design and Features

Let’s talk design. As soon as you look at the device, you will feel the sturdiness of the tool. The specification of the motor is the best size to power ratio any angle grinder has to offer. The device is neither too big nor too small. It is just the right size for precise work.

The DeWalt tool provides you with 1.8 HP motor which more than enough to work. It also provides you with a powerful dust ejection system. It helps to provides durability to the grinder by ejecting damaging dust and debris particles that enter the tool through the various air intake vents. It increases the life of the device significantly.

Inside the box, you get a One-Touch Guard which allows for 360-degree rotation of the guard in a single action. Quite handy, trust me.

The Quick-Change wheel release allows tool free wheel removal without the need of using a wrench. This means you need not carry tons of tool with  the device. A low profile gear case means you easily access tight spaces.

It has a top mounted and protected spindle lock button that helps to maximize the depth of cut without compromising durability.

The paddle switch comes equipped with a safety lock-off system that prevents accidental startup.

The DWE402 packs in an 11 Amp AC/DC motor that can turn your grinding wheel at 11,000 RPM. This is just the right balance of power and size. This makes super easy to use the device.

From the time I bought the DWE402, I haven’t faced a single issue. The dust ejection is remarkable as it helps in keeping the device clean and also free from any debris. It also comes very handy in doing small tasks like sharpening a kitchen knife.

The tool is very simple and convenient to use. I used it for long sessions without any problem. As mentioned earlier the grinder came with a wrench, a threaded locking flange, an unthreaded backing flange, and a case. The box is quite handy for carrying different things around.

Unfortunately, the kit doesn’t contain grinding disks. You need to buy them separately.


Brushes and Gears

Unlike other models, the DWE402 provides an oversized brush. This ensures twice the brush life in the comparison to other brushes. The large spiral bevel gear helps to increase the transmission life of the tool.

All these little modifications helps in elongating the life span of the tool. It is also equipped with a long lasting Paddle Switch. It has a top mounted and protected spindle lock button that maxi-mises the depth of cut without compromising durability.



Quite affordable at $$

Easy to use

Durable and Sturdy build



Doesn’t come with grinding disks

A lower amp model option would be great

Apart from the warranty, the DWE402 comes with 90 days money back guarantee. This means if you are not satisfied with the product you can ask for a full refund.


Customer Feedback

The DWE402 is one of the highest rated angle grinders on Amazon. It has an incredible 4.8 rating from 224 reviews. This speaks a lot about the product.

An Amazon verified buyer says –

“Absolutely best Dewalt 4.5″ grinder compared to other Dewalt grinders. I have 4 Dewalt grinders. All 4 are great tools, but this one is my favorite.

Updated to say; I just ordered 3 more of these grinders. I LOVE the one touch guard!!!! You just bump it against the welding table to rotate it to any position you need….I’m quickly replacing all my grinders with these Dewalts.”


The DWE402 has to be the best 4.5” angle grinder in the market. You can find these grinders being used in all over the industry world and also in schools. The device’s build is quite durable, and the tool will easily last you for years together.

The price is quite low as compared to angle grinders from other companies such as Makita. I have used it for more than 4 hours continuously without any issues.

The only problem I see is the motor. The motor is rated at 11 Amp which is quite high. Unless you need all that power, you may be better off buying a 7 Amp model from Makita or Bosch. This will means less weight and will also help to get into tight spaces. This will also be helpful if you have small hands.
