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 graded the highest. With that said, there are a number of other fantastic options when it comes down to 3 x 21 Inch Belt Sanders. We have them for you here.

Besides the option we covered already, I would definitely take a look at the Makita 9903 and the 352VS by PORTER-CABLE. Both Makita and PORTER-CABLE are considered two of the premier producers of quality Sanders. Both these tools are highly rated also. The Makita advertises a user rating of 4.6/5 when contrasted against the 4.0/5 star rating given to the 352VS by PORTER-CABLE.

The 9903 by Makita provides some truly choice features including Powerful 8.8 AMP motor; only 85dB. The PORTER-CABLE 352VS although, is tough to beat with Variable-speed belt sander with cloth dust bag; variable-speed dial 850-1,300 SFPM plus Belt and gear drive system transfers power from the motor to the sanding belt.

Both of these two options make an exceptional option if you're shopping for 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.
