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.

It's true that the BLACK+DECKER DS321 was the 3 x 21 Inch Belt Sanders that we ranked at the top. With that said, there are a few other superb alternatives when it comes to 3 x 21 Inch Belt Sanders. We have the best of them in this article.

The Makita 9903 and the 352VS by PORTER-CABLE are worthy of a look as well. Both tool brands are popular for their premium Sanders. Both tools are highly rated also. Users awarded the 9903 an average rating of 4.6/5 stars. Contrast that to the 352VS which boasts an average rating of 4.0/5 stars.

The 9903 by Makita offers some very choice features like Powerful 8.8 AMP motor; only 85dB. The PORTER-CABLE 352VS however, is very competitive 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 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.

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.
