          Great cuts
          [This review was collected as part of a promotion.] I bought this saw, used it to make a small shed. It was handy to use to cut 2x4's along with the ply wood siding and roof.

            Sometimes you need a tool
            I had to have this tool to cut out some subfloor, my circular saw was not going to work for the tight spaces I needed to cut it. I probably could have used a jigsaw or something else, but this would give me the best outcome. It works great for that, I have also used this to cut the bottom of a wooden gate so it swings better over grass and to adjust a gate that wouldn't close properly. When you need it you need it, but not much use outside of that. I think I have used it 3-4 times in 5 years.

              Precise and lightweight
              This is an excellent tool for a diy-er. The cuts are very precise and the tool is relatively lightweight. I used the wood blade to remove hideous 90s ceramic border tile and was able to cut right along the grout line and keep the non-border tile intact. The only significant limitation is that I couldn’t get close to the corners. Replacement blades are a bit pricey but the tool saved me a tonne of time!

              Light weight, true cut, very portable
              [This review was collected as part of a promotion.] To be honest I had purchased a different brand saw, was not all happy with it. Purchased the Dremel, no comparison. Great for any size job, and the blade assortment is a big plus for all types of jobs.

                Multi-use Ultra Saw
                [This review was collected as part of a promotion.] I needed a saw for cutting and fitting in close quarters ant the ultra saw was the best tool of choice. I used it to cut kitchen counter tops for sinks and have taken down entire bulkheads when kitchen remodeling.

                  Nice for cabinets Mixed materials
                  [This review was collected as part of a promotion.] Loved how smoothly this little saw worked through wood and pvc. It made the project look very smooth. I made my sewing station with this saw alone. This isn’t an artisan’s work but for someone like me that just wanted a sewing station that was sturdy, this saw got it done.

                    Tough, well built tool!
                    I bought this a couple of months ago, initially in connection with some deferred maintenance on my log home - debarking, trimming back knots and so forth. It performed very well, particularly with the flush wood cutting blade. More recently, I used it in an unrelated project in which I really pushed its limits - and it again performed superbly. I have a low end Craftsman table saw with narrow miter gauge fence channels cast into the aluminum table. I bought an Incra miter fence and noticed that the table channels were nonstandard and too narrow for the Incra fence. The remedy was to enlarge the channels. I set up my ripping fence and, registering off that, cut the channel with this saw using the metal cutting blade. I found that a little WD40 on the cut kept things from getting too hot. Here are two pics - one showing the saw in use and the other showing the result. Fantastic!

                      Depth guessing & sawdust snowing
                      I just received the Dremel ultra saw for my bday from my 14 year old son. I was SO excited to finally save up the $ to purchase this saw that I have wanted for aVERY long time. I unpacked it from the box assembled, added the wood blade and got ready to make my first cut. I was EXTREMELY, I mean EXTREMELY, disappointed to find that there was absolutely NO measurement markings on the saw to adjust the exact depth for cutting. ARE YOU GUYS SERIOUS?! How the heck am I supposed to set the depth for my cuts, exactly?! Am I just supposed to GUESS?! Am I supposed to just hold my breath and hope it doesn’t cut down too far or not far enough?!?! I own SEVERAL Dremel tools and this is the very first tool from Dremel that I have purchased and have been so disappointed in. Y’all really, REALLY let me down on this one. I’m a single mom and first time homeowner and over the years I have gone out of my way to purchase DREMEL tools ONLY because honestly, I think they’re the BEST! As a single mother I need to save and save my $ to purchase “one Dremel tool at a time”, to be able to accumulate a garage full of Dremel tools to do work on my very first house. Unfortunately, I’m not super “skilled” enough to just guess how deep to cut and not ruin what I’m cutting. I don’t have the xtra $ to go out to buy more material because I cut too deep either. I would assume not all of your customers are “professionals” as well and trying to guess the depth can be time consuming having to cut a little, stop to make sure it’s not too deep then cut a little more, stop and check, over and over etc I really have no idea why y'all wouldn’t put measurements like the saw max has. I hope you add them on future ultra saw models. Also another really big disappointment is the dust accessory isn't included with the purchase of your ultra saw. It’s kind of silly, maybe even a little greedy, to sell this accessory SEPARATELY just to make a couple more bucks because without the dust accessory this thing makes a COLOSSAL MESS!!! After being so excited, looking forward to purchasing this and spending MONTHS to save up for this, I am truly, very sadly disappointed with this particular DREMEL tool. :(

                        I've bought this product on 4/29/19. I used it two or three times. Now, it won't restart. I called the Dremel customer service. I was told to send it it to Wisconsin. What a piece of junk! I wish I've bought the Roto razor as advertised on TV ( but I did not want to wait!)

                          Almost perfect tool for floor cutting job
                          I bought the ultra saw for a diy flooring project, it works great for cutting hardwood floor tiles. The dust is super fine when cutting and gets in the way of the sight line. I looked for the dust port adapter online so I could hook it up to my shop-vac and couldnt find it anywhere. Asked customer service where could get it and the rep (Byron W) said he was unable to find it either, including Dremel’s own website. I’m very unhappy with this saw because of this issue.

                          We are very sorry you have had trouble with sourcing the dust port adapter. Please be sure to contact Dremel Customer Service at 1-800-437-3635, M - F, 8 AM - 5 PM, CST, and they can help you get that adapter.
