dewalt angle grinder review

It is easy to come across angle grinder tool reviews that frequently speak about the best brands to achieve the best performance. What nearly all of these reviews have in common is the frequency of reviews that mention DeWalt grinders and this is with good reason.

A DeWalt tool is defined by its stellar performance capabilities and durability with its line of angle grinders receiving frequent praise. DeWalt grinders are consistently evolving to increase durability and performance capabilities with new motors and RPM components appearing frequently.

In this DeWalt angle grinder review and buying guide, we will take a look at some of the best DeWalt grinders as well as additional accessories that come with the various models.

Overview

DeWalt’s company slogan is “Guaranteed Tough”, and tough and durable are definitely guaranteed when it comes to this brand’s line of angle grinders. DeWalt is one of the gold standards within the power tool industry, with several manufacturing facilities that prioritize innovation and user comfort.

DeWalt grinding tools are professional grade pieces of equipment where the size of the blade, the motor, and the variations of RPM speed are frequently calibrated to create both large and small projects effective and simple. Increased variations in motor brushes and dust ejection systems are also hallmarks of this brand’s grinding tools.

Key Features

Some of the most common features of a DeWalt model include:

  • DEWALTs Perform & Protect line is designed to provide a high level of control, dust containment, or low vibration, without sacrificing performance
  • A high power 4.7 HP (maximum motor HP) 8,500 rpm motor with some models scaling up to 11,000 RPM
  • A dust ejection system increases brush life and protect the motor from damaging particles entering the air intake
  • Many models feature an anti-vibe trigger handle that reduces user fatigue caused by vibration
  • A quick change guard that allows a user to quickly adjust the guard to redirect sparks

Performance

Speed, accessibility, comfort, and overall design are some of the standout features of a DeWalt grinding tool. All DeWalt models have a wide range of rpm speeds, which makes them ideal based upon the type of job you are needing to get done.

But the real standout of a DeWalt model is the incredible output and technology that is in place to increase the life of the motor. Another standout feature on most models is the Power-Off Advanced Electronic Overload Protection that shuts the tool off before it reaches overload or burn-up.

With a DeWalt model, you not only get the best features when it comes to grinding but you are also getting the commitment from a company that makes their products durable and long-lasting.

Value for Money

Value for money is also a big selling point when it comes to the grinders from this brand. Not every model is as good or as long-lasting as some, but if you stay within the parameters of what the model is designed for, you will find that your Milwaukee grinder lasts for a long time indeed, which is pretty impressive for a cordless grinder.

Long-lasting performance translates to good value for money. Most models are incredible in their durability, yet you may need to go through a few different discs if you run the grinder at a high speed consistently.

Overall, no matter the price, this brand represents excellent value for money.

Dewalt DWE4599N (9-Inch): (Editor’s #1 Pick)

This model is our number one choice because it is designed to provide a high level of one or more of the following: control, dust containment, or low vibration, without sacrificing performance. This unit has a high power of 4.9 HP (maximum motor HP) with a 6,500 rpm motor that provides overload protection giving higher operating speeds under load.

It also features an E-Clutch System that shuts the tool off when a wheel pinch is detected, which helps in reducing kickback. The anti-vibration side handle reduces the user’s exposure to vibration, and the power-loss reset prevents accidental re-starts following a power disruption when the tool is left in the “on” position.

DeWalt Angle Grinder Buyers Guide

DeWalt has a reputation in selling itself based on high popularity, but keep these key points in mind before buying:

  • Always consider the disc size. DeWalt strives to make most of its models accessible with the industry standard of four and a half inches, which can be used for many smaller projects and most standard grinding and cutting projects. For larger projects, consider using a 6-inch disc. Some models may have a grinding wheel or paddle switch included, therefore, just be sure the model you choose can support the task you wish to accomplish.
  • A high rpm equals better performance. A DeWalt model is almost always going to have some of the best variations in terms of speed and motor efficiency. Just be sure to select a disc or wheel that can handle the speeds that the model is capable of giving.
  • Don’t overdo it. DeWalt is an excellent brand, yet there can be some slight problems with motor performance if you grind for too long. This is fairly common with any brand out there but especially common in models that have higher RPM capabilities–which is most DeWalt brands.

What Does a DeWalt Grinder Do? What Do Customers Say?

When it comes to manufacturing the best angle grinders, DeWalt is a trusted name and for good reason. Some notable features of a DeWalt Angle Grinder include:

  • Spindle Lock Button – This feature helps tighten and loosen the wrench. This means you don’t have to worry about using two wrenches to change disc/wheels.
  • Dust Ejection System – The angle grinder features a dust ejection system that ensures workplace cleanliness. The dust ejection system ensures the durability and longevity of the product since it ejects all the ground material away from the internal mechanisms of the machine.
  • One-Touch Guard – This feature offers 360-degree guard rotation with a single action. This ensures the durability of the machine.
  • Powerful Motor – Most DeWalt grinding tools feature a powerful motor that powers at 11 amps AC/DC. This allows you to operate the grinding wheel at 11,000 RPM. This guarantees good power, weight, and size.
  • Quick-Change Wheel – Handymen can conveniently change the wheels of the grinder with ease without using any high-end tools and equipment.
  • Small Gripping Surface – A DeWalt grinder is comfortable because of its small gripping surface. The small gripping surface allows people to use the tool without experiencing fatigue. This prevents your hand from getting tired from extended usage.

I strive to offer only the best and most accurate information when it comes to power tools, but sometimes, it is important to hear what other users have to say about a product. The quintessential DeWalt DWE402K has an average of 4.8 out of 5 ratings on Amazon with a large majority of positive customer reviews.

This indicates that the majority of customers were pleased with the product and left positive reviews. Most customers agreed that the product was worth every penny and delivered promising results.

While the DWE402K is not as powerful as the 21,000 RPM variants out there. It is more comfortable to use than most power tools in the market and offers less fatigue.

This also prevents you from over-using the machine to the point of causing damage. The power is strong enough to get the job done while you have complete control of the machine. While the machine is not as powerful as other high-end angle grinders in the market, it is suitable for most jobs.

A customer wrote they experienced no issues with the product and that the RPM power was perfect for a wide range of tasks.

A customer wrote the angle grinder can cut through steel like butter. You can also use it to cut through small boat anchors, trailer bolts, doorknobs, or anything else.

As for the spindle lock button, the angle grinder is a top-mounted, well-protected piece of equipment that maximizes cutting depth when you are using the machine. The angle grinder features oversized brushes that have a longer brush life compared to other products in the market.

The grinder features air vents that keep the machine clean and prevents debris from entering inside. As far as the downsides are concerned, the machine does not feature discs and they have to be purchased separately.

Additionally, one Amazon customer claimed the grinder is uncomfortable to hold and is not as ergonomic friendly as compared to other angle grinders in the market. Customers agreed that the product may be difficult to use if you do not have a worker’s build or do not have experience with using bulky machines.

Most negative reviews were related to isolated, incompatible concerns with the lack of additional accessories.
