Rated 3.8 out of 5 by 56 reviewers.
Rated 4 out of 5 by Great Product I purchased this unit after my older unit developed some issues. This new unit is so much better in many ways. The balance on this unit is great and the variable speed is extremely valuable. The extra long power cord is a real plus. I have used it now for about a total of 5-6 hours and I am extremely pleased with it. The one negative is the continuous run button ( allows you to run the unit with out holding the switch trigger) is too small, it is very difficult to activate. Great product. May 19, 2011
Rated 5 out of 5 by Powerfull this is the most powerfull 3x21 in beltsander i have ever used, its heavy but so what all heavy duty tools are. November 18, 2009
Rated 3 out of 5 by ridgid products Good powerfull sander but a little heavy and cumbersome. You think Ridgid would come up with something better April 17, 2008
Rated 4 out of 5 by Mostly good I purchased this sander while I wait for parts to fix my beloved Bosch 1274 DVS, (discontinued, why?). I live in Hawaii and was not able to purchase this product even online. I had to get my sister to purchase it for me online in PA. Even my cousin in CA couldn't purchase this sander but I like the specs and it has a lifetime service contract that they will honor here in Hawaii, but you must purchase the sander through the Home Depot. I've been remodeling homes for 25 years and I can tell you this is the most powerful and smoothest 3x21 belt sander I've ever used, I really like it. Now here are the negatives. 1. I just completed my first project with it, a set of stairs. All the wood had to be milled and sanded so it was a fair amount of work but my Bosch did half the work before the toothed sprocket wore out. Now I already I have to replace the timing belt (drive belt) on this sander. I can't believe it wore out so quickly, I hope this isn't a constant problem with the tool. 2. I thought the top of the sander was flat so that I could use it upside down on my workbench, but it is slightly domed, so close to a perfect design but no, fail. 3. The dust collection is great when it's hooked up to my shop vac but without a vacuum, the air vent for the motor blows right in your face. I guess engineers do their best to think of everything before production but they blew it, so to speak, on this one. Now it's in production and I guess it's too expensive to do a redesign so soon. Maybe that's why it's so cheap. It's obviously a heavy duty sander and I suspect it will last me for the rest of my life. February 8, 2014
Rated 5 out of 5 by Belt sander This is a real nice belt sander and the price was great. A popular magazine reviewed some belt sanders and said that the only thing stopping this one from getting a five star rating was not having variable speed. Well these new ones do. I first tried it out on an old chopping block that was probably as old as I am and was coming apart due to glue failure. I was able to pry all the pieces apart without damaging the wood but the dried up glue needed to be removed and I was amazed at how easily this new belt sander got down to fresh wood. I have bought a number of Ridgid brand tools over the years and I think I'm going to be as happy with this new belt sander as I am with my other Ridgid tools. November 20, 2013
