DeWalt DWE401 Angle Grinder

The DeWalt DWE401 angle grinder offers more raw power than 99% of the angle grinders on the market. It boasts 11,000 RPM (no load), with enough power to cut and grind any material you need. It has a quick-change release that allows you to swap out grinding and cutting wheels with no hassle. It also has a one-touch guard that lets you adjust where your guard sits on a full 360-degree arc.

 

If you’re experienced with angle grinders, you’ll more than likely notice that the body on the DeWalt DWE401 is a bit larger than most other angle grinders. This is a slight negative because it makes it more difficult to hold and get into very tight spaces. It is a minimal issue, but here at Wonkee Donkee, we want to give full balanced reviews.

 

However, DeWalt has altered the design to combat this. The addition of an adjustable side handle and the narrowed hand grip help with ease of use and comfort. The dust ejection system is also very practical, as it helps remove debris away from the device and user quickly.

DeWalt Angle Grinder Buying Guide

We hope we’ve helped you to make your mind with our review of these DeWalt power tools as well as recommendations for which tool is best for different jobs. The good thing about buying DeWalt power tools is that you know you’re getting quality. At Wonkee Donkee we have just tested all DeWalt angle grinders to allow you to pick the best of a good bunch.

 

What we try to do is to utilize our experience to give out buying advice for beginners. If someone doesn’t have any experience of buying an angle grinder before it can be confusing to make your way through the different specifications and knowing exactly what they mean. Our goal is to end this confusion and if you read on, you should get plenty of actionable information from this angle grinder buying guide to help you make the right decision for your particular needs. If you are interested about knowing about other angle grinders from different power tool manufacturers then you should check out our best angle grinder review to find out more.

 

Let’s start by breaking down the main components of an angle grinder, what they mean and why they are important.

Battery

If you’re not used to using power tools, the battery might not seem like an important component to worry over, but it is always the first on our list. Starting right back at the beginning for a second. There are two types of angle grinder: cordless and corded. In 90% of situations, having a cordless angle grinder is so useful. This is because you can literally take it anywhere with you, without having to plan ahead what power sources are available and where you will be plugging it in. Then there’s the additional practicality, cordless angle grinders allow you to get into tight places and get the perfect angle whilst operating. In contrast, these areas and positioning would be difficult to reach with a corded angle grinder option.

 

But the minute you have a cordless angle grinder, it all becomes about the battery. They used to be pretty poor really, as such a high power output required high-quality batteries that just didn’t exist at the time. In previous years, the cordless was secondary to a corded angle grinder, only used for small tasks or difficult angles due to its inability to be operated for long periods of time. Thankfully, technology has now advanced and the cordless angle grinder has become a stonewall power tool in most contractors arsenal. Now that batteries are far more powerful and last so much longer, the roles of the two different types of angle grinders have reversed. The cordless angle grinder is now the mainstay, with some professionals having a bigger corded angle grinder as a secondary tool to deal with large weld projects, to polish larger surfaces.

 

The key thing to look out for is that the battery is lithium-ion. One of the main reasons for this is because they are much lighter than old school batteries. You have to bear in mind that you’re holding the angle grinder for extended periods of time, or holding it at unusual and uncomfortable angels. So after using it for a while, you’ll realise that weight really matters. The other benefit is that they charge so much quicker than other batteries. Once your battery is dead, the quicker you-charge it, the quicker you can get back to work and get the job done.

 

When it comes to DeWalt batteries, they are designed to be compatible across a wide range of their power tools. This means you don’t need to buy a battery for every tool, and then have the headache of trying to ensure they’re all charged. You can charge 1 or 2 batteries for all the tools and clip them in and out of each power tool as you need to use them.

Weight

We’ve spoken about weight already when talking about batteries. But the weight of the tool, without the battery, is equally as important. The reason you buy a cordless angle grinder is that you want to be able to take your angle grinder with you and not have to worry about power sources. You also want to be able to work at different angles. So, it would be utterly counterproductive to have a heavy tool you struggle to hold for extended periods of time.

 

A good angle grinder shouldn’t weigh more than 5 lb (just under 2kg). At Wonkee Donkee, we think that any angle grinder does, then it is probably too heavy. To add to this is will more than likely mean that it doesn’t have the latest technology, and you could be losing out on performance and battery life too.

Motor

From our experience of testing and reviewing power tools, we have found that the majority of DeWalt angle grinders will use brush motor technology. That’s because brush motors are a cheaper technology to implement, which ultimately means that DeWalt is able to create more affordable angle grinders.

 

Here’s the deal with brush motors. They’re a little heavier and not as easy to maintain. They’re also louder. They are inferior to brushless motors. There’s no escaping that. However, it all comes down to what you can and can’t afford.

 

Simply, if you use the angle grinder a lot, its an important tool for your work and you can afford it, go for a brushless angle grinder. They’ll last a little longer and you’ll appreciate the comfort and usability benefits that come with it being lighter. But the reality is, if you don’t really need an angle grinder week in, week out, then we’d suggest going for the cheaper brush motors.

 

Similarly when talking about your budget. You’re not suffering by having a brush motor, they are great motors and can complete the same tasks that a brushless motor completes. You also can afford to have a slightly heavier motor, if overall it’s not a particularly heavy angle grinder. Finally, you’ll be fine with a little extra noise. After all, we’re all used to noise with power tools.
