    • Another De Walt Quality Tool.
Most (95%) of my hand tools are made by Dewalt and this unit replaced a cord and plug connected belt sander (not a De Walt) that I overheated to the point where it is unusable. I have not used this new De walt belt sander much, but the little that I have used this unit, and not having a cord is wonderful and operates smoothly and while I have been told that it eats batteries, I really don't care because I have plenty of Dewalt batteries in my workshop. So, in my opinion, this is a wonderful unit that is made well and was worth the money and it operates very quietly. ... show more

    • No cord, no cord, no cord
No cord, No cord, No cord! First ever cordless belt sander for me and now am selling all my others. The cord was always in the way and I've had to replace several cords because of that. This unit is plenty powerful and with only a 4Ah battery ran for nearly an hour of start/stop cabinet work. The lack of a cord gives unprecedented maneuverability and no surprise cord-pulls during sanding strokes. Would like to see Dewalt make these a bit quieter as they seem noisy for such a small unit. ... show more

    • comfortable to use but battery live far too short
Battery live is short Works well. Good for small projects at home where the use is within 10 to 12 minutes at a time. good weight and comfortable , dust collection excellent. What's the use of the variable speed?

    • This is the 3rd belt sander I bought, gave away the other 2 and kept only this one!
I had two older belt sanders, both corded and the same 6" belt, but always had problems with the cord getting in the way and have several electric tape fixes on the cords. Wanted a powerful belt sander for sanding down the wood siding our our roof deck (Lion wood), to re-seal it with IPE oil (made a mistake and used Spar Varnish and it just peeled off). This tool worked great, I have several DeWalt batteries so as one ran out could just swap it out for another 20v battery and keep on going. Only bad thing is it's heavy, so working on a flat surface is easy, but holding it up on the wall was a bit tough, but liked the dust bag, caught most of the dust I created (still ware a mask), but easy to empty and good capasity. I like the tool, would recommend it especially if you have other DeWalt battery tools! (I have 3 DeWalt drills, and cordless saw). ... show more
