Top 6 Best DeWalt Angle Grinders Reviewed

  1. DeWalt 20V MAX* (DCG413B) ― Top Pick
  2. DeWalt One-Touch Guard (DWE4011) ― Runner-Up
  3. DeWalt FLEXVOLT ADVANTAGE 20V MAX* (DCG416B) ― Great Value
  4. DeWalt (DWE402)
  5. DeWalt (DWE43116)
  6. DeWalt (DCG412B)

To create this DeWalt angle grinder review, I used feedback from my friends, my personal experience with the brand’s tools, and an analysis of hundreds of online reviews.

1. DeWalt 20V MAX* (DCG413B): Top Pick

Specifications:

  • Brand: DEWALT
  • Material: Blend
  • Item Dimensions: 12.2 x 4.7 x 6 inches
  • Style: 20V Brushless 4-1/2″ Grinder (Tool Only)
  • Power Source: Battery Powered

This angle grinder is probably one of the finest tools DeWalt has ever made. I have been using it in my projects for 4 years for fast cutting and sanding of different materials. This model also has thousands of positive reviews online. It will appeal to home DIYers and professionals who don’t like (or can’t) work with a corded model.

I recommend using a battery with a large capacity (at least 5 Ah) to work for more than half an hour because the tool is very powerful. The speed is 9,000 RPM.

You can use any disc with a diameter of 4.5″. The DeWalt 18 V angle grinder is ergonomic and well-balanced. It’s also lightweight (3.75 pounds) and not too noisy. The manufacturer offers many safety features. E-Switch Protection disables the trigger switch at zero voltage. This prevents the tool from turning on unexpectedly when power is applied.

The kickback brake instantly disengages the grinder and stops the disc when it detects a pinch or bind-up. The brushless motor is another advantage of this model. Such motors last much longer and do not require the replacement of brushes.

Positives:
  • Lightweight and ergonomic; 
  • Has the power of a corded tool;
  • Brushless motor; 
  • Has important safety features.
Could be better:
  • Battery and charger are sold separately.

2. DeWalt One-Touch Guard (DWE4011): Runner-Up

Specifications:

  • Brand: DEWALT
  • Material: Blend
  • Item Dimensions: 4.6 x 15.4 x 6.1 inches
  • Style: Angle Grinder Only
  • Power Source: Corded Electric

This tool has a lot of power, as it works from an outlet. Its 7 A motor allows you to reach speeds of 12,000 RPM. It is an excellent choice for concrete cutting, metal grinding, and other hard jobs.

My friend also successfully uses this model to prepare for welding and cutting rebar, working 5 hours a day. He likes the 4.5″ size, which allows him to get into tight spaces and offers enough power to take on any construction/renovation project.

Adjusting the position of the guard is very simple; all you have to do is turn it. You don’t need to use tools. A wrench is also not required to change the wheel, which saves the technician time. A friend praised the ergonomic design and 2-position detachable side handle.

Positives:
  • Ergonomic design; 
  • You can quickly adjust the position of the guard; 
  • Quick wheel change.
Could be better:
  • Brush motor.

3. DeWalt FLEXVOLT ADVANTAGE 20V MAX* (DCG416B): Great Value

Specifications:

  • Brand: DEWALT
  • Material: Blend
  • Item Dimensions: 13.11 x 6.2 x 4.9 inches
  • Style: Angled
  • Power Source: Battery Powered

My neighbor kindly provided this tool for testing. In many ways, this model resembles my favorite DeWalt DCG413B. But this angle grinder is an updated model. One of the benefits is that you can use FLEXVOLT batteries, which provide up to 54% more power and significantly increase runtime even under heavy workloads.

I’ve sanded cement floors and cut steel with the FLEXVOLT battery. One 6 A battery lasts long enough: I could change at least two 5 A regular batteries in that time.

You can use 4.5″ and 5″ discs with this model. The manufacturer has included features such as a kickback brake and protection against accidental start after power outages. The brushless motor has a longer life and produces 9,000 RPM.

I liked the convenient paddle switch and how easy it is to adjust the guard. According to my neighbor, in two years of almost daily use (he has a workshop in the garage), he had no significant issues with this model.

Positives:
  • Brushless motor;
  • Has important safety features;
  • The FLEXVOLT battery lasts much longer than the regular option.
Could be better:
  • Battery and charger are sold separately.

4. DeWalt (DWE402): Best Dust Ejection System

Specifications:

  • Brand: DEWALT
  • Material: Blend
  • Item Dimensions: 15.63 x 5.94 x 4.81 inches
  • Style: Angle Grinder only
  • Power Source: Corded Electric

Among my colleagues, there are many real fans of the brand. One of them has drills, saber saws, and two DeWalt angle grinders. This model is his favorite, as it allows him to work with applications of different levels of complexity. The 11 A motor is powered by an outlet and provides a high speed of 11,000 RPM.

The handle can be screwed to the right or left, which is convenient since my colleague is left-handed. The dust ejection system guarantees a longer grinder life. The paddle switch is simple and convenient, and the guard easily rotates 360 degrees. Professionals will like that you don’t need tools to change wheels.

The 4.5″ wheels are compatible with this model. Overall, this is a quality product with easy handling that doesn’t stall under heavy workloads. On the other hand, it can be a little uncomfortable for extended use as it is quite heavy (6.2 lbs).

Positives:
  • The ergonomic handle is comfortable for both left-handers and right-handers;
  • Changing wheels without tools;
  • There is a dust ejection system.
Could be better:
  • Big weight.

5. DeWalt (DWE43116): More Disk Sizes to Work With

Specifications:

  • Brand: DEWALT
  • Material: Blend
  • Item Dimensions: 18 x 6 x 5 inches
  • Style: Angle Grinder only
  • Power Source: Corded Electric

This model gives you more options because it is small and allows you to use wheels with a diameter of 4.5 to 6 inches. Many 6″ models are quite large and not as comfortable to use. This has become a versatile grinder for my father and his many home projects. The 13 A motor produces 9,000 RPM, and the dust ejection system is indispensable when working with concrete and wood.

My father noted that although the grinder is quite heavy (5.7 pounds), it fits comfortably in hand. The ergonomic handle can be set in two positions, depending on whichever is more convenient for you.

Positives:
  • Dust ejection system; 
  • Compatible with wheel sizes from 4.5 to 6″; 
  • Ergonomic.
Could be better:
  • Brush motor.

6. DeWalt (DCG412B): Best Ergonomics

Specifications:

  • Brand: DEWALT
  • Voltage: ‎20 Volts
  • Item Dimensions: 13.46 x 5.76 x 4.86 inches
  • Power Source: ‎Lithium Ion

This model has been one of my favorite DeWalt instruments for 8 years now. The quality is so high that I’m sure my grandchildren will get the grinder. Enough power to work on heavy projects.

The maximum no-load speed is 8,000 RPM. I have a lot of batteries of different capacities. If you plan to use the grinder often and for a long time, buy at least two 4 Ah lithium-Ion batteries (the model is also compatible with FLEXVOLT options).

This grinder works with 4.5″ wheels. I also like the comfortable handle that can be adjusted in two positions. Replacing discs and adjusting the guard is simple and requires no tools. I like that this model is powerful but not too noisy. The 2-finger trigger switch with a lock button is very convenient.

Positives:
  • Not too noisy; 
  • Comfortable handle and trigger switch; 
  • Easy wheel change and guard adjustment.
Could be better:
  • Brush motor.

Buyer’s Guide: DeWalt Angle Grinder

When choosing a tool, you should decide on your needs. You should pay special attention to the following points before buying an angle grinder. DeWalt offers decent quality but also a wide selection. Some models may be more convenient for you.

DeWalt Angle Grinder

1. Power

DeWalt offers battery-powered and corded angle grinders. Corded models have more power and provide higher speed (RPM). However, many craftsmen do not like the inconvenience of the cord’s presence. Cordless models are powerful enough to do the same job as corded models.

To work for a long time, you need to have several large-capacity batteries (I recommend at least 4 Ah). FLEXVOLT batteries also provide better performance through longer battery life.

The power potential of cordless models is measured in Volts (V), and corded options are measured in Amps (A). Of course, the higher the number, the more powerful the tool.

2. Size and weight

The size of a grinder is the diameter of the wheel that is compatible with it. Most DeWalt models offer 4.5″ and 5″ models. This common size makes it easy to complete most projects (cutting concrete, wood, grinding metal sheets, and so on).

Weight is a significant characteristic, especially if you need to work or hold the grinder over your head for a long time. Most DeWalt models are lightweight ― 4 to 5 pounds.

3. Switch types

DeWalt prefers instruments with both slide and paddle switches. Therefore, you have a choice if you prefer a particular type of switch. For models of this brand, a slide switch is more common. Both options are quite convenient. However, if you wear gloves while working and want more control, an angle grinder with a paddle switch is a better option.

4. Blade

For DeWalt models, you can use different brands of discs, depending on the application. The most common size is 4.5 inches. It is an excellent choice for most grinding and cutting jobs on a variety of materials. In addition, the smaller wheel diameter is safer at high speeds and gives you more control in tight spaces.

Please note that discs with a maximum allowable speed of, for example, 6,650 RPM cannot be used with grinders that are faster than this value. This can cause part of the wheel to break off and fly toward you at high speed.

5. Safety

If you are a beginner with a grinder, be sure to read the basic safety rules. Many DeWalt models also have additional features to help prevent tool breakage and injury.

The kickback brake function stops the wheel and turns off the motor when a jam or pinch is detected. E-switch protection is also a critical safety feature. This function is activated when the voltage becomes zero. After the power is restored, the disk will not suddenly start spinning for you. To continue working, you will need to restart the switch (first turn it off and then back on again).

FAQ on DeWalt Angle Grinders

This brand makes reliable tools that even professionals prefer. Below are answers to popular questions for those just getting to know DeWalt.

How to change the blade on a DeWalt angle grinder?

Before changing the blade, unplug the grinder from the outlet or remove the battery. Find the special button on the top of the head. Click on it and unscrew the nut that holds the disc. Remove the wheel and install a new one. Fix it from above with a nut. It can be tightened either by hand or with a hex wrench.

What is the best DeWalt angle grinder?

It all depends on your preferences and needs. My recommendation is DeWalt Angle Grinder 20 V MAX* (DCG413B). This model is also the brand’s bestseller on Amazon and is preferred by professionals and home craftsmen.

What grease for the DeWalt angle grinder?

It’s best to use DeWalt’s factory specialty grease, as different experiments can break the grinder. In addition, you do not need to lubricate the parts too often and abundantly, and the universal grease is suitable for most tools (regardless of power source and brand).
