Is this variable speed?
Although the product description says it's ideal for electricians, do you think I could cut concrete if I were to use a 4 1/2 in diamond blade?

Powerful, Reliable, and Convenient Grinder – DEWALT Does It Again!

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!

Awesome Price!

I picked this up on sale for less than $70. Of course, as are all DeWalt tools, it is great! I have never bee a big fan of the yellow and black, but the quality and reliability is certainly worth the little lack of visual appeal.

Guard difficulties

Exactly as anticipated. Guard is a little weird to lock in but you figure it out. Please do not throw away your guard. Not always easy to move but can save you a serious injury.

Nice grinder with a paddle switch

The DCG413B is a nice upgrade from the DCG412B. The upgraded design of both the locking flange and "wrench" makes it easier to mount or remove wheels. The paddle switch feels comfortable to engage. However, the built-in safety release switch that is part of the paddle trigger is kind of annoying. The handle is much thicker than the DCG412B to hold in the hand. With a 5 AH battery attached, its weight isn't cumbersome for me to operate for quick grinding and cutting tasks. Lastly, the brushless and brake stop features were the reason I upgraded.

Tool only experiance

Excellent tool. Brushless motor means no damage from water if operating in a wet environment or sand if dropped in the dirt. Trade evolution offers a tool only experance so I dont have to pay for cheep batteries/2A chargers/ tool bag that I don't need or will ever use.
