    • Powerful, Reliable, and Convenient Grinder – DEWALT Does It Again!
Style: 20V 4-1/2" Grinder (Tool Only) Pattern Name: Grinder
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! ... show more

    • Well designed.
Style: 20V Brushless 4-1/2" Grinder (Tool Only) Pattern Name: Grinder
So far just used for twisted wire brush on rust, worked great, with little drain on a generic 4Ah battery. Weight is fine, balance good. I like the hex wrench system for tightening the arbor screw; much more likely to be readily available if the provided wrench is lost or forgotten. 6K RPM's plenty adequate for light to moderate jobs. Tool seems well thought out to me. The complaints about stopping with overheating and binding are a little hard to understand given that these are built in safety and longevity features thoroughly covered in the instructions. This is not equal to a plug in tool, as is true of all battery powered tools. I expect if a constant heavy load is put on it the battery will run down quickly, and the motor is likely to overheat given the constraints of battery powered tools. Just physics, folks. If you want 10K+ RPM and ability to do constant heavy cutting or grinding, use something with a cord! ... show more

    • hands down, better than a corded version

Angle Grinder for Carving and Sculpting Wood Once you pick a certain brand of cordless tools, you’ll likely need to stick with that brand to simplify the charging process. It also qill provide you with a few more battery packs at your disposal when you’re using a tool frequently. As you might suspect, I picked DeWalt as my go-to brand and have invested in a few of their cordless tools. The power and reliability are good, and for some tools (like this one), the versatility is a game changer. When combined with a Kutzall carving blade, this tool making it super easy to carve and sculpt hard wood. I’ve been working on Maloof style rocking chairs most recently and accessibility to the deepest corners of the chair is key. Recommend highly, here’s a link to get one for yourself ... https://amzn.to/3yPVWN0 ... show more

    • Reliable Grinder for Various Tasks
Style: 20V 4-1/2" Grinder (Tool Only) Pattern Name: Grinder
This DEWALT grinder feels solid and handles different materials well. The 20V battery provides enough power for most jobs, and it’s easy to control. The tool-free guard adjustment is useful for quick changes. Works well for grinding and cutting without any issues.

I have used this a number of times for cutting steel roof panels and it has worked flawlessly. I wish I would have bought one earlier!

    • Great tool. Terrible Battery Life!
Style: 20V Brushless 4-1/2" Grinder (Tool Only) Pattern Name: Grinder
I love DeWalt tools. I really do. I think almost every tool I own is a DeWalt. And this is a really good grinder. I wasn't even that irritated that it didn't come with a battery or any blades, because the 20v batteries are so interchangeable. The only issue I have is the extremely short battery life! And I do mean SHORT. A fully charged short pack gives you about 5 minutes of use on this thing. Switched it to the thick pack that I use on my chainsaw and that bumped it up to about 15 minutes or use. If you are a contractor or something other than a home improvement DIY'er, this thing would be a serious disappointment! Everything else about it, I love. The grip, the weight... But man, it sucks the life out of a battery! ... show more
