Style: 20V MAX Cut-Off Tool
As a longtime DEWALT fan, I’m once again blown away by the quality and performance of the DEWALT DCG412B 20V MAX* Lithium Ion 4-1/2” Grinder! DEWALT has been my go-to brand for power tools for years, and this grinder continues to uphold the company’s reputation for delivering top-notch, durable, and reliable tools. Let’s talk about the performance—this grinder is a powerhouse! With its 8,000 RPM motor, it easily tackles even the toughest cutting and grinding jobs. Whether I’m grinding metal, cutting through concrete, or working on DIY projects, this grinder has the power I need to get the job done efficiently. It doesn’t stall, and it stays cool even after extended use, which is something I really appreciate in a tool. One feature I absolutely love is the Quick-Change Wheel Release. As someone who’s used grinders that require a wrench to change the wheels, I can tell you that this tool-free wheel removal is a game-changer. It makes switching out wheels incredibly easy, saving me so much time and frustration. The tool-free guard adjustment is another convenience that adds to the overall ease of use—no need to struggle with a wrench when adjusting the guard position, which makes it so much quicker to move between tasks. DEWALT also thought about comfort and control with this grinder. The 2-finger trigger switch with the lock-off button makes it easy to activate and provides a more comfortable grip. I especially appreciate the 2-position side handle, which gives me more control and comfort, particularly during longer projects. I can easily switch positions to ensure I’m always in the most ergonomic and efficient stance. I also love that this is a bare-tool model. Since I already have other DEWALT 20V tools, I can use the same batteries, which is both cost-effective and convenient. I don’t have to worry about buying extra batteries or chargers, which is a huge plus in my book. The 4.64-pound weight is just right—not too heavy to make it cumbersome but sturdy enough to give me the balance and control I need. The construction feels solid, and I have no doubt this grinder will hold up for years to come. DEWALT always makes tools that are built to last, and this grinder is no exception. Overall, I can’t recommend the DEWALT DCG412B enough. As a DEWALT loyalist, I trust their products to provide power, durability, and ease of use, and this grinder hits all the marks. Whether you’re a professional or a DIYer, this grinder is a fantastic tool to have in your collection. I’m absolutely thrilled with my purchase and will continue to trust DEWALT for all of my future tool needs!

Amazing and convenient! We have always owned an electric grinder... for many years. We always thought it would be more powerful and would never "run out" of battery. We were happily surprised by how much power this battery powered grinder had!! It was able to complete our project, while using it all day long! We were cutting through rebar and thick metal horse fencing this time. I can't say enough about how nice it is to mot have a cord, and be constrained by WHERE we could use our grinder... it is freeing.

This DeWalt 20V Grinder is a great value for DIY or hobbyist use. It has a comfortable grip and works great on most tasks. Its can cut through sheet metal and rebar fairly easily (with a quality cut-off wheel). Also, with the grinder disc, makes it easy to clean off burrs and other jagged edges. It is fairly compact, not as small as corded grinder, but this is offset by the portability.

A little stupid, and not super powerful. It is clearly not a flagship unit, you can tell by how rough and unrefined the torque delivery is. But for me, I rarely use an angle grinder. I didn't need 60v, an XR, or anything over the top. It's easy to handle, and has good ergonomics. It takes material out with absolute ease, my only complaint is how unrefined it seems, very clearly not their primary concern of a tool. Plenty power for me though.

Admittingly, I never owned a grinder before purchasing the DCG412. I had used a small air powered die grinder in the past, as well a larger disc sander. But I never really had a need for a grinder. That is, not until I got this one. As with most of the new Dewalt 20V Max tools I have purchased, I first set out to find out what accessories were available and then acquired them. I had to go through a learning curve to understand why I couldn't use 5/8" grinding wheels on a grinder with a 5/8" shaft (7/8" only), but once I figured that out, I was in acquisition mode. I have an assortment of metal & concrete cutting/grinding wheels, flap discs/wheels, carbide blades, and wire wheels. I found the enclosed top wheel cover and spare flanges/nuts at eReplacementParts. I even found a thin sided wrench on Amazon to tighten the inner nut on the fixed hub wheels. Unfortunately, the wrench wasn't quite thin enough, so I used the DCG412 to take a 1/6" off of each face. Now that's ironic. Everything fits nicely in a 15" Dewalt bag. No use having a powerful tool and then not having the proper $4.00 accessory when you really need it. I have only used this grinder 3 or 4 times for real projects so far, as well as dozen test grinds and cuts on various materials. The results have been better than expected. Still kicking myself for not owning one of these years ago. A multitude of projects that could have been simplified with a grinder and the proper accessory. Be sure to have a spare battery or two handy, as the DCG412 uses a good amount of juice to do what it does. Now I understand why Dewalt does not make any cordless sanders, that often need to run for really long periods of time. Being cord free though, makes the DCG412 a joy to use. Nothing to get tangled while you're changing guards or attachments. And nothing to trip over, allowing you to focus on your work. That's rather important when working with grinder, a potentially dangerous tool in inattentive hands. Safety first.

What a workhorse! I read several reviews for this 'light-weight' grinder, but it ground work to dust! I was grinding a soft, 3mm punched plate to form a cutting edge, and it did the job great. It did go through two batteries to get there, but it did the job and never backed down. I would not recommend this for grinding over 6mm. Great tool and highly recommend but bring extra batts.
