Criteria for Choosing the Best DeWalt Grinders


Perhaps one of the most important considerations while shopping around for a DeWalt grinder is performance. As a rule of thumb, grinders with big discs pack more power than their counterparts with smaller discs. Be careful not to go for one with the biggest disc just because you read about it here.

For optimal performance, ensure the size of the disc matches the job you want to undertake. Also, keep in mind that devices with stronger motors are ideal for extreme, high-intensity applications so for normal, everyday cutting and grinding around the house, consider going with a model with the most suitable motor size. The same goes for speed; leave the really fast options for professionals.


If you don’t want headaches using your device, choose carefully where you commit your money. A dust management system helps keep debris and dust from work area and workpiece, helping with productivity and efficiency. Secondly, consider the physical dimensions. Lightweight and compact options are a lot easier to use.

They keep your hands comfortable and give you hassle-free access to tight and confined spaces. If the handle has over-molding grip and is adjustable, you’ll have superior control and manoeuvrability. If the DeWalt grinder dampens vibrations, that would be better. Another feature is the soft start.


You can discount the significance of safety when using one. A few essential safety features can be the difference between going back home with all ten fingers and ending up in a hospital finger with a severed hand or fingers.

Repositioning the guard and changing discs should be easy and tool-less. An automatic shutdown also comes in handy in case of unexpected mechanical issues and other performance hiccups.

Frequently Asked Questions

Q: What’s the procedure for removing an angle grinder disc?

A: In most cases, manufacturers include a two-pronged fork for turning the drive bolt in an anti-clockwise direction. A second wrench is provided for stopping the fork from turning. There are several other options, too.

Q: Are DeWalt grinders ideal for cutting metal?

A: Yes. They are versatile and cut not just metal but also rebar tile, stucco. You can also use them to polish, clean, sand, and even sharpen various objects and materials.


The aim of the buying guide was to impart on you the knowledge and information necessary for making an independent, informed decision. The best DeWalt grinder is one with most or ideally all of the essential feature to enable you to perform optimally.

Whether you’re a professional or DIY enthusiast, sacrificing quality, construction, ease of use, and practicality will be a costly mistake. The most important take away though is that you should ensure your choice of tool is suited to the project you intend to undertake.
