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 undoubtedly our number one 3 x 21 Inch Belt Belt Sanders. However, there were several other very premium 3 x 21 Inch Belt Belt Sanders we wanted to showcase here that just barely missed first place.

Next up is built by WEN which is a very trusted tool brand. WEN's Belt Sanders are no exception. I was excited to try out the model 6321 and I was not let down!

The model 6321 Belt Sander by WEN, at $43.18 is a particularly great Belt Sander for the price. The WEN 6321 is definitely a sound alternative. Of you are uncertain about our number one choice, I'd advise to opt for this Belt Sander.

The 9903 by Makita and the 352VS by PORTER-CABLE are worth looking into as well. Both these tool manufactures are thought to be a couple of the leading manufacturers of premium Belt Sanders. Both tools are top rated also. Real customers gave the Makita an score on average of 4.6/5 stars. You can liken that to the PORTER-CABLE 352VS which boasts an average score of 4.0/5 stars.

The Makita 9903 comes with a couple of features you might not get on competing Belt Sanders. For example Powerful 8.8 AMP motor; only 85dB. The 352VS by PORTER-CABLE although, is very competitive offering 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.

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.
