The DEWALT 20 in. Variable-Speed Scroll Saw helps you create accurate, detailed workpieces and has a user-friendly configuration with easily accessible controls, reduced vibration design and variable-speed performance. Featuring a double parallel-link arm design for accurate cuts, the arm pivots from the back to the front, shortening the distance the arm moves for smoother, quieter operation. Easy to handle with variable-speed control for application-specific performance, the on/off switch, speed control, blade-tensioning lever and flexible dust blower are all located within easy reach of the front upper arm. The dependable 1.3 amp motor delivers 400 to 1750 SPM for plenty of power, while the compact design makes portability around your jobsite or workshop a breeze. Durable for years of reliable use, this saw has a cast iron table that bevels 45 degrees to the left and 45 degrees to the right for versatility and also provides excellent support.

Rated 4.5 out of 5 by 55 reviewers.
Rated 4.0 out of 5.0 by Good saw for the money Such an upgrade from the Ryobi which I would tell anyone looking to buy a scroll saw to stay away from and invest the extra money in a Dewalt!!!! Almost "NO" vibration. Makes excellent cuts. The blower keeps the dust out of the way. Blade changes are a breeze. However, I have to tap the side sometimes to get it to the dialed in speed when I turn it on. Other than that I would highly recommend this saw to anyone. Wish I would have pay the extra from the start. January 27, 2015
Rated 5.0 out of 5.0 by 99% Dust free I've been waiting for sale on DeWALT scroll saw. It was a good chance to buy it. But I didn't know there were lots of dust. I don't like to wear a mask while scrollsawing. So, I made this. Now, I'm really satisfied with it. Next time, I'm going to post some pictures again that it is 99.9% dust freee. September 15, 2013
Rated 5.0 out of 5.0 by Good purchase Great saw , easy to operate and use! The only thing that needs to be done to improve this is to have a lock on the arm to hold it up for changing the blades. I use a 4x4 x4 wood block to hold the arm up to change the blades, it works good. This is a great saw ! December 23, 2014
Rated 5.0 out of 5.0 by Works fabulous! Great Scroll Saw! This scroll saw is amazing! This would be good for a hobbyist or professional. We started out with a cheap model elsewhere to see if we would continue scrolling and decided an upgrade is in order. Wish we would have gotten this sooner! The quick blade changing has made pieces that took 40 minutes only take about 10- maybe less. We turned it on and put a nickle on it's side. Great scroll saw!!! July 3, 2014
Rated 5.0 out of 5.0 by Very happy with my new Dewalt scrollsaw. I had won a perfect score, two first places, and two second place ribbons in a local woodworking contest over the last 5 years, without my Dewalt scrollsaw. Scrolling over 15 years and after 4 other scroll saws, I see now that I should have purchased this scroll saw 5 years ago. There is much less vibration and of course, it has a deeper throat. Maybe, I could have placed all perfect scores. Thanks for a very good product. April 26, 2013
Rated 3.0 out of 5.0 by Solid machine but could be better Super easy to set up and get going. I took many people's advice and purchased Flying Dutchman blades and have been very happy with the overall quality of the saw and the cutting performance. Places where improvements need to be made are in the guide. I am constantly fighting with it as it doesnt stay in one place, plus it is too far away from the blade to hold the material down sufficiently. I put the guide in a vice and bent it considerably and now it rest on either side of the blade and that has helped a bit but it still moves around. I used a rockwell saw in the past and the guide was much more rugged and came right down tight to the blade. Point number 2: The blower does a great job of keeping the cutting area free of sawdust... until you cut really slowly which you need to do for some things. At slow speeds the blower doesnt work well at all. The other thing you need to fight with is the blade attachment screws. As you tighten them the blade tends to rotate with the screw... you really need to pay attention to get the blade straight up and down. My other suggestion would be to get TWO lights for the saw... one one either side of the blade. Otherwise you get an annoying strobe effect as the blade goes up and down. Make sure you bolt the saw down to a solid workbench or table to reduce vibration. Overall though, I am happy with the saw. May 16, 2013
