Angle grinders are super-handy tools that’ll come in handy in a wide range of projects. From sanding to shaping to buffing and polishing, an angle grinder will be your best friend in and out of your workshop. But like any power tool, it’s not a good idea to pick one up without doing the research or… you know… relying on the research done by others who have a bit more knowledge and have a lot more time on their hands.

In this article, we’re going to compare two angle grinders produced by two of the world’s most well-known manufacturers – the BDEG400 from BLACK+DECKER and the DWE402 from DEWALT. Each of these products has received an overwhelming number of thumbs ups from their customers. So which of the two should you pick up the next time you’re shopping onlineLet’s find out together.

Motor Power

BLACK+DECKER BDEG400
The strength of the motor is an indicator of what the angle grinder can do. A higher amp rating is directly related to versatility – stronger motors for grinding and shaping metal, whereas weaker motors are used typically for wood and plastic. The B+D features a 6-amp motor, making this tool great for removing rust and even sharpening metal tools.

DEWALT DWE402
This DEWALT angle grinder is a beast of a tool that comes equipped with a beefy 11-amp motor. With this much power, this tool can grind and shape hard metals as easily as it can sand wood and buff the body of your car (use the appropriate attachment, please).

Conclusion: The B+D’s 6-amp motor doesn’t make it weak by any standards, but if you’re looking for something that can do everything an angle grinder is designed to do, the DEWALT is the tool to go with. With nearly twice as much power as the B+D, this too will perform admirably in all cutting and shaping applications on any material imaginable.

Disc Size

BLACK+DECKER BDEG400 and DEWALT DWE402
One of the most important considerations to make before picking up an angle grinder is the size of the disc. Both of these angle grinders are designed to use 4-1/2-inch discs which are on the small side of the disc spectrum. A 4-1/2-inch disc is ideal for adding finishing touches on metalworking and woodworking projects as it offers the user much more control. This is also great for making intricate cuts in smaller workpieces. However, this is not the most efficient size when it comes to buffing large metal sheets and car bodies.

Speed

BLACK+DECKER BDEG400
The speed at which the angle grinder’s disc rotates is of the utmost importance when it comes to working with different materials and what sort of projects you’re doing. For instance, grinding welds can be done at high speed, but polishing metal to give it a shiny finish is best done at slower speeds. The B+D operates at a maximum of 10,000 RPM but does not come with variable speed controls.

DEWALT DWE402
The more powerful motor allows the DEWALT to work at a higher speed than the B+D. This tool has a speed rating of 11,000 RPM. It’s important to note that a 1,000-RPM difference beyond 10,000 RPM is immaterial when looking at the larger picture. And just like the B+D, this unit doesn’t come with a speed control option.

Conclusion: The lack of speed control hampers these tools’ overall versatility. Your only option is to grind away at your workpiece at their maximum speeds. This can be troublesome for users who are just learning how to operate an angle grinder. It can also cause problems when working with new, never-before-used materials.

Dust Management

BLACK+DECKER BDEG400
Angle grinders are notorious for producing copious amounts of dust which can be hazardous to your health. This is especially dangerous when working with metal as shrapnel can pierce the skin and lead to infection. The B+D does not come with any onboard dust extractor or ejection port so any dust and debris that finds its way into the tool can cause severe damage to the motor.

DEWALT DWE402
The DEWALT doesn’t have the same problem as the B+D. Instead, it features a proprietary dust ejection system with an internal fan that separates debris from the suctioned air, blasting away dust and metal grindings out of the back-end port. This feature should extend the life of the tool far beyond the manufacturer’s 3-year warranty.

Conclusion: It goes without saying, but any dust extraction feature is better than nothing at all. And the best thing is that DEWALT’s dust ejection system is that it works. No more clogging inside of the motor’s casing which can cause it to sputter and die prematurely. It’s a shame that the B+D angle grinder doesn’t have any such system.

Durability

BLACK+DECKER BDEG400
A big part of an angle grinder’s overall durability is its construction. Like most angle grinders on the market, the B+D has a metal housing that encases its motor. The handle is made of plastic which we found to be quite durable and able to withstand falls without cracking. Unfortunately, that’s all that the B+D has going for it.

DEWALT DWE402
The DEWALT’s several safety features protect the tool from a premature death, making it arguably one of the best angle grinders available today. Like the B+D, the motor sits within a metal housing, and the handle is made of durable plastic. Besides, the motor comes with larger brushes which extend the life by up to two times before replacing. The tool also comes with an auto-off feature which kills the unit when the brushes become too worn out.

Conclusion: If you’re looking for a tool that’ll last much longer than its warranty while also providing the same performance quality as the day it came out of the box, the DEWALT is the closest you can get. With the assortment of safety features, this is arguably one of the most durable.

Wheel Guard

BLACK+DECKER BDEG400
The wheel guard is the semi-circular piece that rests around the grinding disc. It protects your hand and fingers from accidentally making contact with the spinning disc. It’s important that the wheel guard can be locked into place to prevent it from spinning and bumping into your hand or workpiece. Unfortunately, for many customers out there, the B+D’s wheel guard is too loose to be reliable. It’s almost impossible to lock in place.

DEWALT DWE402
The DEWALT’s wheel guard does not have this issue. The one-touch 360° guard rotates smoothly and locks into place without the slightest hitch. The way the guard is repositioned is by pulling it slightly or even hitting it against your work surface. After being nudged, it’ll automatically lock into place.

Conclusion: So basically, the DEWALT is a much more reliable tool than the B+D in regards to protecting the user. The B+D’s wheel guard is too loose and often spins on its own accord, whereas the DEWALT locks into place but is also extremely easy to shift positions.

Wheel Change

BLACK+DECKER BDEG400
Being able to swap out wheels is what makes an angle grinder such a versatile tool. There are sanding discs, buffing pads, metal-grinding wire pads, and any attachment for a wide range of different applications. The B+D comes with a spanner wrench which users use to tighten and detach the flange. For some reason, the spanner wrench is made of plastic and will undoubtedly warp in shape within the first couple of uses.

DEWALT DWE402
The DEWALT doesn’t require the use of an external tool to swap out wheels. No longer will users need to fumble with spanner wrenches to loosen the flange and swap blades. Instead, the DEWALT comes with a quick-release button that detaches the wheel.

Conclusion: The convenience of changing blades without a spanner wrench makes the DEWALT a tool for pros. Most angle grinders use some sort of tool to detach the wheel, so the B+D isn’t bad just because swapping wheels requires a spanner wrench. But what is disappointing is the quality of the spanner wrench.

Handle Positions

BLACK+DECKER BDEG400
Most angle grinders come with a detachable side handle which can move from left to right depending on your preference or how much clearance you have on either side. The B+D goes one step beyond and has a center position where the handle can be mounted. An upward-facing handle might seem laughable until you find yourself working in tight spaces.

DEWALT DWE402
The DEWALT belongs to the 99.9% of angle grinders with left and right ports where the side handle attaches to. There’s nothing special about the DEWALT in this regard.

Conclusion: The center position of the B+D’s detachable handle can come in handy on several occasions, especially where you’re workspace does not offer much horizontal space and movement. In these very specific situations, the B+D would be the optimal angle grinder to use.

Verdict

In our humble opinion, we feel that the DEWALT DWE402 is the better angle grinder compared to the BLACK+DECKER BDEG400 by a rather sizable margin. These two angle grinders use the same disc size, but the DEWAT’s motor is nearly twice as powerful as the B+D’s. There are also several nice features that are either absent in the B+D or are inferior compared to DEWALT. The only thing that the B+D has that’s not available in the DEWALT is the vertical handle port which, if we’re honest, is not the most important feature to have. Take it from us: the DEWALT DWE402 is the much, much better angle grinder.
