DeWalt DCG412 – The Basics


Just like the grinders manufactured by the rival companies, such as Bosch or Makita, the DeWalt DCG412 can also be used for numerous applications. The primary one is, of course, grinding – and it’s something that this unit is very good at. The reason behind this is the presence of a powerful 8,000 RPM engine that is controlled via the variable speed trigger and which achieves a performance that is nothing less but impressive.

Of course, the DCG412 also sports a design featured on all other power tools manufactured by this company – it is, in other words, highly ergonomic and exceptionally easy to handle. Changing the wheel on this grinder is yet another smooth and straightforward operation, as it comes with a quick-change system that allows tool-free wheel swapping. Let’s analyze all of these characteristics in detail:

The Features


The Design


Sporting the signature black & yellow appearance, the DeWalt DCG412 has a look that is quite similar to that of the other power tools of this company. It’s a relatively compact, well-balanced grinder with a rubberized back handle, so handling it is pretty easy no matter how challenging the task you’re working on is.

But even so, DeWalt decided to equip this unit with a convenient 2-position side handle. Its presence provides not only greater control over the grinder, but also makes working with it far more comfortable and versatile. Just like the back handle, it also features a rubber over-molding that prevents slippage while working.

Power


As we said, the heart of this grinder is its strong 8,000 RPM motor, advertised by DeWalt as a high-power engine that provides unmatched performance. This is mostly true since DCG412 is more than capable of assisting the user with the most grinding and cutting applications.

The unit’s speed is controlled through the integrated 2-finger trigger with a lock-off button.

Quick-Change Wheel Release


One particularly noteworthy thing about DeWalt DCG412 is the fact that it comes with the company’s signature Quick-Change wheel release. As the name suggests, this feature allows the user to change the wheel quick and easy, and without the need to use a wrench. This is very convenient and significantly speeds up the swapping process – professional contractors will undoubtedly appreciate this feature.

Warranty


The warranty deal on this grinder is a standard DeWalt one – 3-year limited warranty, 90-day money back guarantee, and one year of free service. The inclusion of a free-service contract is especially significant when we consider the fact that DeWalt has more than 60 service centers all over the United States.

Things We Liked / Didn’t Like

R

Things we liked about it

This grinder’s design is one of the easiest things to like about it – it fits great into hands and is very easy to control. The thing that makes this possible is the presence of two handles, both of which are rubberized and have an ergonomic shape.

8,000 RPM of speed is quite impressive, particularly when we consider how reasonably priced DCG412 is. Although not brushless, the engine of this grinder is quite robust and will provide you with enough power to deal with both light and heavy-duty grinding tasks.

Another thing we liked about this DeWalt grinder is its Quick-Switch wheel release system. As we already mentioned, it allows tool-less swapping of wheels.

Q

Things we didn’t like

What users say is true – this grinder burns the battery fairly quickly. This is our only major complaint about DCG412, although we do realize that its high performance had to come with a price.

We also found the unit’s manual to be quite lacking when it comes to lists and part numbers. Moreover, it fails to describe what wheels are available for this grinder and what their potential uses are.

General Impressions


The majority of users agree that DCG412 is yet another excellent DeWalt tool, and they’re quite pleased with its performance, design, and price. They claim that the unit is quite helpful and that it has enough power for most of their grinding and cutting needs.

However, most of them advise getting extra batteries when purchasing the model – the fact that it sucks through the battery really fast is something everyone agrees on. This is precisely why DCG412 is best for quick cuts – longer sessions are reserved for corded models. 

Conclusion


All in all, the weight, comfort, performance, and the noise level of this grinder are all on the good side. The DCG412 is undoubtedly one of the best grinders in its price category and a real problem for the rivals coming for Bosch, Makita, Black & Decker, Milwaukee, and other manufacturers. A fine addition to DeWalt’s lineup of 20V Max tools, the model is bound to become a favorite of many handymen – consider it for purchase if you’re searching for a branded budget-friendly grinder.
