Sanding is overrated, and hand sanding, just plain sucks!

I recently took the DeWalt 5-inch variable speed random orbital sander DWE6423K into my workshop to evaluate.  As a remodeling carpenter who also enjoys woodworking, I can attest that when you need a smoothly sanded surface, or need to remove finish between final finish coats, nothing beats a random orbital sander. When used with long, sweeping strokes a random orbital sander gets the job done quickly, and leaves behind very few sanding and mill marks.  It allows you to sand with the grain, or across it with outstanding results.

There are two major things that you need to know about this sander;  first it is part of the DEWALT’s Perform and Protect line.  This means it was designed to control and contain dust and provide lower vibration to the user, without sacrificing performance.

Reduction in vibration

To reduce vibration, this sander has a separate internal counterweight that provides less vibration, allowing the user to have more comfort and control. Additionally a nicely designed, comfortable, over-mold handle increases hand comfort during sanding applications.

DeWalt designed two methods to collect dust;

  • Attached dust bag
  • Built in shop vac connection

Additionally, an innovative rubber skirt, minimizes dust escaping from around the sanding pad. The dust collection port has a one handed locking dust bag that works with all DeWalt dust extractors and universal connectors system.  I found it  connected nicely to my shop vacuum, and was extremely efficient at collecting dust.

concordcarpentertoolreview-58Size and Power

This orbital sander has a low profile design, which allows you to get into more compact spaces, in closer to surfaces and it weighs only 2.9 pounds, making it easy to weild.  It has a 3 amp motor which delivers 8000 to 12,000 rpm on a 3/32″orbit.

This sander uses 5-ince [125mm] hook and loop, sanding discs with an 8-hole dust extraction pattern.


I have only used the sander a handful of times.  The only negative I have with it, is that the cord is too short.

How’s it Perform?

The DeWalt 5-inch variable speed random orbital sander DWE6423K worked exceptionally well.  I loved its size, power and immediately noticed that the tool vibrates way less than my older model sander.
