DEWALT DWE6423K Random Orbit Sander Review

Whether you work on wood or metal, nothing compares to having a high-quality orbital sander in your tool box. This handy device allows you to smooth out almost any surface with ease, and because it is hand-held, you can work on virtually any project without interruption.

If you’re in need of an orbital sander and you’re looking for the best option out there, then I would highly recommend the DeWalt DWE6423K Random Orbit Sander. This device sets the gold standard for sanders and will help you get the job done, no matter what it is.

Let’s take a look and see what this machine can do for you.

DEWALT DWE6423K Random Orbit Sander

Who Needs this Device?

When it comes to different sanders, you have a lot of options from which to choose. Random orbital sanders, however, are ideal for woodworkers. The reason for this is that you can get a smooth surface in an incredibly short amount of time without leaving any marks or swirls on the finish. Also, because an orbital sander has holes, it picks up debris as you work so that you aren’t covering everything in wood dust.

These sanders can also help with metal finishing if you want to create a smooth polish without leaving scuff marks. Overall, if you work on large, flat pieces of wood or metal, then this is the machine for you.

High-Speed Motor

Part of the reason to use a power sander is that you can work faster and get the job done more efficiently. In this case, the DeWalt DWE6423K comes with a 3.0 amp motor that operates between eight thousand or twelve thousand rpm. That means that you can get a pristine finish in much less time, thus making your workshop run at peak efficiency.

Compact Design

What makes this device so convenient and versatile is its size. It’s large enough to help you cover surfaces quickly, but it’s also small enough to do some detail work if need be. In fact, this sander only weighs four pounds, making it one of the lightest models you can find.

Another benefit of the compact design is that it’s built to reduce vibration. If you’ve used a power sander before you know how it can make your hand tired after a while, which forces you to take breaks to recover. Fortunately, the DeWalt Sander is insulated with rubber to reduce fatigue so you can work longer without interruption.

Built-in Dust Bag

As I mentioned above, the reason that orbital sanders are so popular with woodworkers is that it picks up the dust as it’s generated. Eight holes on the device suck up all debris while you work so that you can spend less time cleaning and stay more focused on the task at hand. Everything is collected in a proprietary dust bag that is vacuum sealed so that nothing will get out.

Best of all, you can attach and remove the bag with one hand, making it much easier to empty and clean out when the time comes. Also, if you have a hose attachment that fits the device you can hook it up to a vacuum directly so that you can work longer. Finally, the on/off switch for this sander is protected against dust, so you don’t have to worry about keeping it clean.

Adjustable Speed Settings

As I mentioned, this sander operates between eight thousand and twelve thousand rpm. To adjust the speed, there is a knob on the top. The placement of this knob is ideal for working quickly. You can move up or down with your thumb, making it much faster to work overall.
