DeWalt 20V Die Grinder Review

The die grinder is one of the most versatile tools you can have in your toolbox. Despite this, it is not one of the most popular. Unlike a hammer or a screwdriver, die grinders are not used for every project, but anyone working with metal or wood can use it for several reasons. 

Not all die grinders have the same composition. So, if you need an updated version of this tool or want to add it to your collection officially, you need to find the right one. In this review, you can find all you need to know about die grinders and if the DeWalt 20V Die Grinder is the right one for your toolbox. 

The Importance of a Die Grinder

A die grinder is a handheld tool used mostly for metal. Artisans and repair people can also use it for plastic and wood. Overall, it is a rotating device that can remove material from a workpiece. 

Usually, people can replace the attachments according to the project or the workpiece. Depending on this attachment, the die grinder can polish, sand, cut, or grind different objects. It can rework dies, polish metal, remove rust, sharpen edges, and smoothen surfaces. 

While it may not be the most necessary tool for your workshop, a die grinder can add the final touches to a project. 

What to Consider When Buying a New Die Grinder

Die grinders have different features that affect which one you should buy. When browsing through, it is critical to keep your comfort in mind. As with most other tools, a die grinder that is easy to use produces the best results for your project. Here is what to consider:

Collet size: This measurement is, essentially, the chuck size of the grinder. It determines how big or how small the bit is. The most common die grinders have a ¼-inch collet size, or 5/8 inch. 

Power: Being a handheld rotating device, a die grinder must have a power source to operate. However, this is where many grinders differ. The two primary sources of power are electric and pneumatic. Electric is the most popular and most efficient since it relies on battery power. The pneumatic power source often requires an air compressor but tends to stay on the cheaper side. 

Power rating: The higher the power rating, the batter performance. When looking at an electric die grinder, the power usually measures in volts. Typically, they only have 18V or 20V options. For pneumatic die grinders, the power gets measured in HP. So, there is a choice between ¼ HP or ½ HP. The power rating you choose should be based on the heaviness of the workpieces. 

Size and weight: Since it is a handheld tool, a die grinder should be at a comfortable weight for you to maneuver comfortably. One that is too heavy can leave your projects untidy and your arm fatigued. Plus, a smaller tool is excellent for storage and uses in small, compact places.

The DeWalt 20V Die Grinder has an LED light attached to the nose to provide clear visibility while in use. Meanwhile, the handle has a smooth grip that can be held at different angles, supporting user comfort. 

The total item weight is less than four pounds; 3.39 pounds, to be exact. This means that the grinder is easy to wield as you cut, smoothen, and polish your projects. 


As an electric die grinder, the DeWalt 20V Die Grinder performs excellently. Since it is cordless, it is easy to use, and the battery life lasts for a long time. It works well for metal, plastic, and wood- especially for at-home DIYs. 

The LED is a particular stand-out feature. This dramatically improves visibility when locating the material surface. Plus, the light helps ensure that the entire surface is completely smooth, sharpened, or whatever else you want it to be. Not all die grinders have this feature, so DeWalt 20V Die Grinder goes above and beyond others with the LED light. 

There is also a trigger that clearly labels the varying speeds. The different speeds option makes the die grinder even more versatile. As functional as it already is, the DeWalt 20V Die Grinder’s speed options let you choose the appropriate speed of friction for whatever material you may be using. 


Die grinders are not necessarily known to be one of the more dangerous tools in the workshop. However, as a rotating device that can cut and polish, there is a level of danger.
