The DEWALT DWE6421 5-inch random orbital sander is the tool to reach for when you need a clean, smooth finish on wood, drywall, or painted surfaces. With a 3-amp motor spinning at 12,000 OPM, it removes material quickly while the separate counterweight keeps vibrations low. The compact, shorter body lets you work closer to the surface, and the rubber overmold grip feels secure in your hand.
The single-speed 12,000 OPM motor is a sweet spot for finish sanding: fast enough to make progress, smooth enough to avoid swirl marks. The 5-inch hook-and-loop pad holds sandpaper firmly and makes swaps a breeze. For dust control, the included dust bag collects the mess, or you can connect the sander directly to a DEWALT DWV010 or DWV012 dust collector for almost dust-free work.
Over time, the hook-and-loop surface wears out. To replace the pad, unplug the sander, remove the center pad screw if equipped, pull the old pad away, and press a new 5-inch interface pad into place. Tighten any screws, and you're ready to sand again. Keep the sander's air vents clear and empty the dust bag regularly for consistent performance.
The separate counterweight system dramatically reduces vibration compared to older designs, which means less fatigue during long sanding sessions. The rubber overmold wraps the critical contact points, and the improved dust-sealed switch resists particle ingestion for a longer switch life. Whether you're prepping for paint or finishing a project, the DWE6421 gives you professional results without the arm numbing.

A 5-inch random orbital sander is the go-to for medium and final sanding on flat surfaces. At 12,000 OPM, it removes material efficiently and leaves a uniform finish. Practice on scrap to get the feel for applying even pressure.
Use sanding discs with the same 5-inch hook-and-loop backing. Choose a finer grit for finish work and a coarser grit for rough sanding. When the pad's hooks are worn, replace the entire pad to keep discs secure.
You can use the included dust bag for quick cleanups or connect the sander to the DEWALT DWV010 or DWV012 dust collector. A dust collector creates better airflow and captures more fine dust, which is better for your lungs and keeps the work area cleaner.
The low-vibration design and rubber grip reduce hand fatigue. To get closer to edges and corners, the shorter body gives you better control. Keep a light touch and let the sander do the work.
Unplug the sander, remove the center pad screw if equipped, pull the old pad off the backing, align the new 5-inch hook-and-loop pad, and tighten. Check the manual for the correct orientation and screw location.
Yes, you can connect a compatible DEWALT dust collector like DWV010 or DWV012, or use the included dust bag.
No, it's a single-speed model at 12,000 OPM, which is a sweet spot for most finishing work.
Use 5-inch hook-and-loop discs. Choose coarse grit (60-80) for material removal, medium (100-150) for general sanding, and fine (180-220+) for finish work.
Smooth and powerful.
This sander is very easy to control. It leaves a fine finish. The dust collection is effective.
I've been sanding drywall and wood with this sander. It has a 3-amp motor that doesn't bog down under pressure. The 12,000 OPM is plenty for fast material removal. The hook-and-loop pad holds paper securely. The dust canister is a bit small, but I connect it to a shop vac and it's nearly dust-free. The vibration is minimal. It's a well-built tool. I'm very pleased.
It gets the job done. The hook-and-loop pad is convenient. It's a bit noisy, but that's expected. Good value.
I use this to refinish furniture. It's smooth and doesn't leave swirl marks. It's comfortable to hold.
I've had other sanders and this blows them away. The motor is strong. It's well balanced. The dust collection works well. I recommend it.
I'm not a pro, but this sander is easy to handle. It's not too heavy. The paper attaches easily. I sanded my deck with it and it worked fine.
I do custom cabinetry. This sander gives a flawless finish. The low vibration is a plus for long days. It's a keeper.
Great for my small projects. It's light and easy to control. The dust box is handy. Highly recommend.
It works, but the dust bag is flimsy and detaches often. The sander itself is fine. I'd prefer a stronger dust collection. It's acceptable for the price.
