  • 3.0 Amp motor spins the pad at 8,000 - 12,000 OPM
  • Shorter height minimizes the distance between user and work piece
  • Design reduces vibration and the rubber over-mold in critical areas reduces user fatigue
  • Dust-sealed switch for dust protection for longer switch life
  • Dust bag has one-hand locking system

The Dewalt DWE6423K is an electric random orbital sander. It is neither the cheapest nor the most expensive product in the market, but offers a solid solution for your sanding needs, with a variable speed control and dust collection bag, it comes packaged in a neat little carry case.

Dust & Abrasives

The DWE6423K is supplied with a 5” backing pad with a standard hook and loop surface for quick and convenient switch out of abrasives. Backing pads are replaceable, but moving to a larger one would offset the position of the vacuum holes, potentially leaving them inactive. As it stands, the backing pad supports 8-holed circular abrasive discs.

The sander is designed to work with either a dust bag or it is able to connect to a vacuum dust removal system. If you wish to attach it to a vacuum system with a 1.25” hose, you will have to additionally purchase a Dewalt universal quick connector. When you buy the sander though you are provided with a dust bag that connects securely with a one-handed locking mechanism.

Power & Speed

To turn the device on and off, a front mounted switch is located right below where your index finger would rest. The switch is dust sealed to provide a longer switch life. Adjustment comes in the form of a rear mounted dial and allows one to transition between finishing and stock removal, with overlap.

At 120V, the device will draw up to 3A, which lets the motor spin between 8,000 and 12,000 OPM. In general, we find that for really smooth finishes a slower speed is more preferable, although most jobs can probably be completed at 8,000 OPM. Going full speed though, the device will happily grind away at any material. To help reduce the vibration of the tool, Dewalt have implemented a separate counterweight, making it more comfortable to use and reducing fatigue.

Size & Ergonomics

At just 2.9lb, the Dewalt DWE6423K is one of the lighter electric random orbital sanders on the market. At just over 10” in length, and only as wide as its backing pad, a good tool is provided in a small package. A small design means it’s easier to get into the corners, although it can sometimes impact the ease of handling of a tool. To counter this though a large palm grip is located above the sander. The grip has a rubber over-mold to improve sanding comfort, and make it easier to hold.

A defining feature of this tool is its shorter height. At only 5.5” tall, it allows users to get closer to the workpiece. This helps from a stability perspective as the potential for lever action to upset grinding pressure is reduced, improve force distribution of the abrasive, leading to a more even and regular finish, both when removing material, or finishing.
