Model DCG405N comes without a case, while model DCG405NT comes with a case.

A cordless angle grinder with a brushless motor with a useful power of 800 W. The tool is designed to work with abrasive discs and flap wheels with a diameter of 125 mm. The DeWALT DCG405NT angle grinder can be used for cutting metal, cleaning welds, processing chamfers, grinding surfaces and other tasks. The reliability of the tool is ensured by the presence of electronic engine protection and a safety clutch that protects against kickback in the event of jamming of the equipment.

The engine brake quickly stops the disk when the button is released, so this angle grinder is well suited for work associated with frequent switching on and off of the tool. The angle grinder comes with an additional handle and a plastic case for storing and carrying the angle grinder with accessories. The battery and charger are not included. A battery from the DeWALT 18V XR family is required to power the tool.

Model overview based on user reviews  
The DeWALT DCG405N is a highly regarded angle grinder, praised for its power, comfortable grip, and compactness. Users appreciate its quality materials and find it to be a great helper for working with metal, concrete, and tiles. It is particularly beneficial for those who already own DeWALT cordless equipment, as it fits seamlessly into the existing setup. While it lacks speed control, which might be necessary for delicate work, it excels in tasks requiring a reliable and powerful tool. The grinder is simple, convenient, and can be operated one-handed, saving time and effort. However, it does not include a basic strap or attachment point for safety, which could be a concern for preventing falls. Overall, it is an excellent auxiliary tool for small jobs, especially where using an extension cord is inconvenient.

Cons

great model, love it

I finally bought a DeWALT DCG405N 6B90D, this device. I bought it for a variety of jobs, to sharpen it little by little, to cut off a couple of fittings, to quickly sand small areas, to correct tiles, to easily saw off a 50mm steel angle with a 2A battery. A gufchem for small jobs, for which unwinding the extension cord turns into great difficulties. Using it fully as an ordinary grinder is stupid, the tool is exclusively an auxiliary tool for the network tool.
The tool is simple, convenient and one-handed. Saves a lot of time and effort.
There is no basic strap or hole where you can attach the device to the foxes. Let's say protecting a fall from a height or crooked hands.
