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 really our number one 3 x 21 Inch Belt Sanders. Even so, there were a handful of other very premium 3 x 21 Inch Belt Sanders worth showcasing here that just barely missed the mark.

WEN is an additional top maker of Sanders. They produce the tool next up on our list. WEN's Belt Sanders are no exception. I was eager to have a go at the model 6321 and I was not disappointed!

This Belt Sander is only $43.18. That is a fantastic deal for a premium Sander like the 6321 by WEN. The WEN 6321 is really a sound option. Of you are uncertain about our number one pick, I'd suggest you opt for this Sander.

WEN 6321 Features

7-amp motor rotates the belt at over 13 feet per second

Compact design weighs in at a mere six pounds to limit the fatigue of the user

Includes a detachable dust bag to minimize clean-up

Lock-in safety feature allows for continuous sanding without requiring a constant grip on the trigger

Backed by a two-year warranty and a nationwide network of skilled technicians

In addition to the option we covered already, I would definitely evaluate the Makita 9903 and the PORTER-CABLE 352VS. Both Makita and PORTER-CABLE are famous for their top quality Sanders. Each of these particular tools received great buyer ratings also. The 9903 boasts a score of 4.6/5 as compared to 4.0/5 star rating received by the PORTER-CABLE 352VS.

The Makita 9903 offers a few really premium features such as Powerful 8.8 AMP motor; only 85dB. The 352VS by PORTER-CABLE however, is hard 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 couple selections make a superb choice if you're in the market for 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.

It is very maneuverable and the dust catcher works great also. I'm handy enough to modify and improve the parts so no biggie. Also you can choose 13 different speed for better control. I compared several other units and decided on this one. This is not a light weight, cheap tool, but a well made tool.
