I give it four stars because I have only had it for four days. The variable speed is amazing for the serious wood worker. We restore 4-6 pieces of furniture a year here at the house. Also take a short break every 15 minutes to let belt cool off. And that was with the 80 grit sanding belt that comes with it.

The BLACK+DECKER DS321 was our preferred 3 x 21 Inch Belt Sanders. That being said, there are several other fantastic alternatives when it comes down to 3 x 21 Inch Belt Sanders. We have a breakdown of them here.

Next up is manufactured by WEN which is a very respectable tool supplier. WEN's Belt Sanders are no exception. It was fantastic to try out the 6321. I was very satisfied using this tool!

This Belt Sander is just $43.18. That is an exceptional deal for a superior Sander like the 6321 by WEN. If you not sure about our number one selection, I'd check out the WEN 6321 next. It's a first class tool at a terrific price.

The Makita 9903 and the PORTER-CABLE 352VS are worthy of a look as well. Both Makita and PORTER-CABLE are considered a couple of the leading producers of premium Sanders. Both these tools are highly rated as well. Users awarded the Makita an score on average of 4.6/5 stars. Contrast that to the 352VS which holds an average rating of 4.0/5 stars.

The 9903 by Makita has a couple of features you might not experience on other similar Belt Sanders. For example Powerful 8.8 AMP motor; only 85dB. The PORTER-CABLE 352VS however, is hard to beat featuring Variable-speed belt sander with cloth dust bag; variable-speed dial 850-1,300 SFPM and even Belt and gear drive system transfers power from the motor to the sanding belt.

I would be eager to suggest both of these 3 x 21 Inch Belt Sanders

I just bought a house and it needed to be redo my back patio. For the price, all things considered, this is a good value. I am a finish carpenter and use my sanders constantly. If I had to choose one I'd take the Makita over this model. Great value vs similar, more expensive belt sanders.

It is very maneuverable and the dust catcher works great also. The brushes are replaceable in the event that they wear out. All the others died completely after about a floor and a half. I will have no problem buying from this seller again! Pair with the new 9ah batteries it's well worth the money.

I got some replacements and within a week they were arcing. He must be happy for he has been in the shop for hours! It's light, easy to hold, and gets into tight corners. I use it a lot for flattening hardwood panels after glue up. I've since used it myself and was please what it could do.

I'd certainly recommend this powerful and well priced sander. Tracks well and doesn't tend to wander like some of old. However it has two things that makes me rate it 4 stars. Make sure the belts moves the same directions as the wood grain. I recently used it to sand rough cut 2x4 and 2x6 pine.
