I got some replacements and within a week they were arcing. With the WEN, I don't hesitate to even sand thin veneers. The WEN really showed it mettle, though, removing stock. I compared several other units and decided on this one. Unfortunately, did not work well on the deck I bought it for.

The BLACK+DECKER DS321 was undoubtedly our preferred 3 x 21 Inch Belt Sanders. Having said that, there were several other truly premium quality 3 x 21 Inch Belt Sanders we wanted to show you here that only just missed the mark.

Next on our list is manufactured by WEN known to be a very highly regarded tool manufacturer. WEN's Belt Sanders are no exception. It was great to test the 6321. I was very satisfied with this tool!

This Belt Sander is merely $43.18. That is an exceptional deal for a high quality Sander like the 6321 by WEN. The WEN 6321 is really a solid option. Of you are uncertain about our number one pick, I'd advise to select this Sander.

Apart from the selections we already included, I would definitely have a look at the Makita 9903 and the 352VS by PORTER-CABLE. Both Makita and PORTER-CABLE are regarded as some of the best suppliers of high quality Sanders. Both of these two options are rated highly as well. Genuine customers awarded the Makita an average rating of 4.6/5 stars. You can compare that to the PORTER-CABLE 352VS which holds an average rating of 4.0/5 stars.

The Makita 9903 comes with several features you wont get on other similar Belt Sanders. For example Powerful 8.8 AMP motor; only 85dB. The 352VS by PORTER-CABLE by comparison, 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.

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

May not last forever but I won't use it all that often anyway. The belts track well with minor adjustments to the knob. However it has two things that makes me rate it 4 stars. The sander works very well and the price was reasonable. This is not a light weight, cheap tool, but a well made tool.

It is very maneuverable and the dust catcher works great also. I can't believe how well it works for the price too. Also you can choose 13 different speed for better control. I received this product for free in exchange for this review. I recently used it to sand rough cut 2x4 and 2x6 pine.

I bought this to work on a table I built for a friend. After it lost the roughness I bought 3x18 belts from Walmart. This one is heavy duty compared to my little round one. The sander works very well and the price was reasonable. And that was with the 80 grit sanding belt that comes with it.

The glue that held them up was impossible to sand off by hand. But at the end of the day I'd take a good look at the TACKLIFE. All the others died completely after about a floor and a half. Otherwise, the nose wants to rise up off the work piece. Reminiscent of the old worm drive porter cable sanders.

The glue that held them up was impossible to sand off by hand. About a half hour of effort after identifying the problem. I paused it for short periods when it showed signs of slowing. This is equipped with a cord much longer than necessary. I used it for the better part of 2 hours with no issues.

This is very similar to my old one with a few differences. After it lost the roughness I bought 3x18 belts from Walmart. I did it in my yard to i don't really care about dust. Also take a short break every 15 minutes to let belt cool off. It's sander that you have to apply a lot of hand pressure to.

It is very maneuverable and the dust catcher works great also. Tracks well and doesn't tend to wander like some of old. I am a finish carpenter and use my sanders constantly. I received this product for free in exchange for this review. Pair with the new 9ah batteries it's well worth the money.
