This heavy-duty angle grinder from Dewalt is no joking matter. Strong, heavy and powerful, this tool can handle any job you throw at it.

It’s strong, powerful motor delivers blazingly-fast speeds that can make short work of whatever project you have in mind. In addition, it has a few nice bells and whistles to sweeten the deal even further.
WHAT WE LIKE
Easily Adjustable
As you work, the angle of your approach can change. Dewalt recognized this and provided an easy-to-adjust spark guard to help protect you from your work. In addition, the spindle lock button makes it simple and quick to switch out attachments as you need to move from one application to another.

An angle grinder needs to last, and Dewalt makes sure this one will. It comes with external brush caps so it’s easy to clean, and the sealed bearings help avoid any corrosion or wearing of the motor.

Another strong entry in this list is the Makita GA7021. While probably not as well known as Dewalt, Makita has quietly garnered a reputation for building high-quality, reliable tools. This angle grinder is no exception. At first glance it might not seem quite as heavy-duty as the Dewalt, but don’t let that fool you.
WHAT WE LIKE
Built For Comfort
One thing the Makita does well is make itself inviting and easy to use. With an angle grinder, you’re looking at a lot of speed and motion, which can be difficult and uncomfortable to control. The GA7021 has a rubberized soft grip handle that can be adjusted into multiple positions, giving you the ability to work comfortably without putting a strain on your hands or arms. Even more, the wheel guard can be quickly adjusted without the need for tools.

Another solid entry by Makita, the GA7031 is essentially the GA7021, but up one notch. This is the GA7021’s bigger, more powerful cousin. Because of that, you can expect the same great quality and features, all in a slightly sturdier, more powerful package

You can’t go wrong with Bosch, and this 7-inch grinder shows that. Once again, we have a very powerful grinding tool that really cuts through a variety of materials with quick and easy precision. Thisgrinder is every bit as powerful as the GA7031 – but weighs significantly less. You can thank German engineering for that. It also has some other great features.
WHAT WE LIKE
German Innovation
Let’s face it: many of the angle grinders here sport similar features. They boast a comfortable grip or adjustable components. Bosch takes those ideas a step further. It’s patented vibration control helps to reduce movement and vibration up to 50% more than comparable models by other manufacturers, making this the most comfortable grinder on this list.
In addition, the included “dead man’s switch” helps ensure your safety, as the grinder will shut off if dropped or not held correctly. This can help prevent a multitude of accidents. Furthermore, the Bosch 1974-8 even helps to take care of itself, with special service minder brushes that will turn the grinder off when maintenance is required, providing an even longer life for this tool.
PROS
- Powerful and Reliable
- Dead man’s switch for safety
- Service Minder brushes shut off tool when it’s time for maintenance
- Patented vibration control technology makes this tool comfortable to use
CONS
- Automatic maintenance shutdown can be inconvenient when a project is time-sensitive

Buyer’s Guide
When purchasing an angle grinder, there are a few factors to consider. First, how powerful is it, and will that work for the job you have in mind? The angle grinders we’ve featured here are known for their overall performance, but still, some grinders work better than others, and it’s important to know you’re getting the right one for your job.
Second, how easy is it to use? You should be able to adjust the grip, the guards, and the wheels to your liking. Does the manufacturer make it easy to do this, or is it a series of steps that can really slow you down?
Finally, how easy is it to maintain? The grinders featured here all try to keep dust out of their systems, but nothing is ever 100% foolproof. When there’s a problem, how easy is it to detect and fix it? Can you clean it easily?
Conclusion
When putting all of this together, there are some grinders that rise higher than others, but for us, the best choice on this list is the Dewalt Angle Grinder Kiot. Not only is it powerful, easy to use, and easy to maintain, but with the entire kit at your disposal, you’re definitely getting more for your hard-earned money. Enjoy the grinder, and get to work!
