Product Description
The DWE6421 5-inch Single Speed Random Orbital Sander with hook and loop pad has a 3-amp motor that delivers 12,000 OPM. The separate counterweight reduces vibration and along with the rubber overmold grip provides comfortable sanding. A shorter design allows users to get closer to the work surface and the one-handed locking dust bag attaches securely to the sander to aid in dust collection or the user can attach the power sander directly to the DWV010 or DWV012 dust collectors.

This orbital sander is powerful. I used it to sand (the ends of) plywood with 3M sandpaper* (80, 100, and 220) and sanding was quick and easy. The filter works great, but be sure to empty it every so often for best results. The only thing I didn't like about this sander was the on/off switch, because the rubber protection cover was probably made for a larger switch, and the switch is a little hard to find (no jokes please). Very minor complaint for me.
*Do yourself a favor and use 3M sandpaper.
I believe I bought this on sale and at the price I got it at (if I recall correctly ~50) I would definately recommend it, but it is worth more than that (I'd buy it again at a non-sale price, now that I know it's good) - I scored on the Amazon Prime sale for sure! I received no compensation for this review.

5.0 out of 5 stars Fácil de usar
Color: MultiVerified PurchaseSuper, yo lo ocupo para trabajos en casa y esta genial, el contenedor para el polvo ayuda sigue botando pero en menor cantidad. Se calienta un poco después de cierto tiempo de uso, aunque supongo es normal, lo he tenido varios meses (6 meses aprox) y con un uso constante y hasta el momento funcionando al 100.

5.0 out of 5 stars Makes sanding almost enjoyable!
Color: MultiVerified PurchasePicked up one of these random orbit sanders when Amazon had one of their woodworking sales, as I've wanted one for my hobby woodworking projects for a while. As I'd expected having owned quite a few Dewalt tools over the years this sander is great, I'm really pleased with it.
I was a bit sceptical of the dust bag, generally on sanders they never seem to do an awful lot - I've been pleasantly surprised how much dust this one collects! I'd say it's about as good as a sander is going to get dust wise anyway. Big improvement over my old B&D 1/4 sheet finish sander!
The dust bag is fabric, attached to a plastic 'socket' - this pushes onto the dust port and twists to secure so it's not going to fall off. There's a lot of airflow through the dust port (switch it on without the dust bag and you'll see what I mean).
The hook and loop sanding discs stay in place well, there's plenty enough power whatever your sanding task. This sander isn't light, and isn't overly heavy - just the right kind of weight, and the weight is also nicely centred over the sanding pad so I've found you don't need to apply as much pressure as with other sanders I've tried - so much less tiring on the hands and wrists.
The body of the sander is the usual black rubbery finish so it's nice and grippy, even when covered in sanding dust. Shape and size I find very comfortable. In the box you get the sander, dust bag and owners manual. That's all, no bag, no sanding discs or anything. I've been using Dewalt branded discs in 240 grit, and Bosch for 80 and 120 grit. All have performed well on this sander and last well.
Overall really pleased I got this sander, it's made sanding almost enjoyable and noticeably easier and quicker - I'd happily recommend this to anyone looking for a mid-price orbital sander. I looked at various different ones from other big brands which were about $30-$100 more than the price of this one, and couldn't really see any benefit to spending double. Glad I got this and saved my money.
My only gripe - Dewalt don't be so cheap, please put a few sanding discs in the box...
Hope that helps.

1.0 out of 5 stars Extremely Disappointing!
Color: MultiVerified PurchaseI regret purchasing this item. It broke on the very first day while using it for its intended purpose. To make matters worse, it does not come with a UK plug or socket—it’s imported from Brazil and has a USA plug instead! Now, I have to go through the hassle of requesting a refund.
I even bought a UK power adapter separately, thinking it would solve the issue, but the product failed on its first use. Absolutely unacceptable quality. Avoid this at all costs
