All good

The instructions were thorough and the parts installed very well. I needed to widen the fence slightly to accommodate the rubber boot. Not a problem, just a comment. Since installation, I have cut 60 plywood parts at both 90 and 45 degrees and estimate it collects 90+ percent of the dust compared to 50% with the stock system. I'm very satisfied with its performance.

Awesome

Dust collection is greatly improved, pretty good design. Two sticking points for me are that the flexible tubing included in the kit could be longer in order to get the connection point off the top/back of the saw. Also, the 3D printed material did not weld properly on my unit, and the surface of the interior was rough with a nest of errant strands of material that had to be sanded away before use.
Cameron C.
Simple install and works great with the festool dust extractor.
Jared
So much better than the factory dust collection. While this does bit catch 100% of the particles, it is a HUGE difference. I did notice that cut soeed does play into the amount of dust the shroud is aboe to collect, slower = better.
Daniel F.
Love the design and how well it collects dust. Not so thrilled about the material its constructed out of. I use my sliding miter saw to install stair banisters 5 days a week. I started using this shop nation dust collection port 18 months ago, and I am now on my third one. They crack and chip very easily due to small cutoff ejections and accidental colliding of the fence and dust port. At $62 delivered every 9 months Im not sure if I will keep buying them. I think the proof of concept is there and I would love to see them injection molded or possibly 3d printed with a shock resistant material.
Nathan
100 times better. This is what should come stock with an miter saw. Outstanding piece of equipment. Highly recommend this product.

On March 7, 2026 I ordered a dust collection chute. It arrived on March 16, 2026. Easier to track on USPS website than the SHOP app. No written installation instructions included. Installation video is too fast and hard to follow. New dust collector is a slight improvement from old. I have a new DeWalt DWS 780 with a new 100 tooth 12 inch blade hooked to a 3 hp vacuum.
Thomas w.
It's a big improvement from the original and I am satisfied with the purchase. Installation was a breeze while watching the video.
Tom G.
Dust collection compared to stock is way better with this kit. Install was easy and tutorial video helped. I should not have procrastinated on upgrading long as I did.
Don F.
I misread the number on my Dewalt 790. I heard the instructions on the installation video to check the number, and installed the rubber flap on the part with the four screws. When it wouldn’t fit, I contacted customer service who was very polite, but said since the rubber flap had been damaged by the screws, it probably wasn’t returnable. My fault entirely. I asked if there were plans to make one for the 790 so I could enjoy the product. She wasn’t aware of any plans to make that model.
I should have made sure before I ordered and installed. Lesson learned. Still think it’s a great product. Just can’t use it.
Dennis W.
The only hang up was at the post office. The label printing was incomplete as the the first column was mostly missing so I'd check your printing. I was able to do a re-delivery and picked it up this morning.
Joe L.
Overall I like the product, at first glance I was skeptical however upon installation and operation I like it.
I have a zero clearance fence so that affects it drawing in more dust than I believe it’s capable of but it’s a noticeable improvement from the oem option and other simple mods I had used. One thing I would suggest is a tighter lock on the adaptive couplers, mine has unlocked and come apart numerous times in a short span of operation, it’s not a deal breaker as nothing more than tape, adhesive or other to hold it more permanently, it easily remedied in shop.
That’s the one thing that held me back from a five star rating.
I’d buy more products and recommend Shop Nation anytime.

I haven't even connected the shop vac yet due to a hose size problem, but I can already see the difference. It is awesome watching the saw dust stream out of the adapter hose rather than blowing all over the place with the production solution from Dewalt. They ought to license your solution.
randy w.
I have only used this a little so far. It seems to work good and was easy to install. It showed up in a timely fashion too.
Tom W.
Everything was great
James W.
Installation instructions were easy to follow, and it works as advertised. I now look forward to using my miter saw instead of dreading the post use cleanup. Awesome addition to any miter saw!! I will suggest this to all my friends and colleagues that have a need for dust collection on their miter saws!!
Steve H.
This attachment has really made a difference in the amount of sawdust collected in my vac.
For the kind of cuts I make most of the time (3/4” flat on the table of the saw) it is amazing how little dust is left on the saw. I have been cutting some thicker material lately and I would say the amount of dust collected goes down as the thickness increases. But even with that, it’s a great improvement over the original dust chute.
Ken R.
Fits the saws well and does a good job collecting sawdust.
Jamie W.
Recently installed the dust upgrade component from shopnation for my Dewalt dws780. Extremely easy to fit and an easy video to follow for those needing instructions. The parts supplied all feel of a good quality and everything built together very nicely. The hose of my Festool midi fit snuggly within the port. For those expecting to completely eliminate mitre dust this is not for you. However it is a huge improvement on the dewalt standard set up. I run a few test pieces of 18mm ply and pine 2x4 on fitting the upgrade and was immediately impressed. On cutting at a slow speed you can clearly see possibly 90% of dust is being drawn through the extraction piece. For anybody unsure whether to buy one of these as an easy example, I'm a tradesman and keen DIYer - hobbyist. I work in a very small space in my garage and normally i would be cleaning the saw every 10 cuts to avoid the dust. With this upgrade the cleaning looks like it will just be at the end of the day from now on
Kevin H.
It's way better than what was on my DeWalt 780. There's a couple of things in my setup that I need to do that will contain the little amount of dust that is left.
Jan C.
Easy to install and does a great job.
William M.
It's works a little better than stock but not much. The cost doesn't seem to outweigh the benefit. Not sure if I can totally blame the device as I'm not using the recommended vac system
Richard G.
Had high hopes for this system. It does work better than the original but I’d say it gets about 60% of the dust. I would buy it again though.
Dan B.
Works great!
Chris V.
Works much better than the OEM design
Matt I.
Could not be more happier with the results of the dust collection!!! I would say more than 95% reduction in the amount of dust into the air and onto the miter saw table. Like the difference between night and day! I added the extra long flexble hose and routed it thru the table to the vacuum below the table. I also added a switch that turns on the vacuum when I turn on the saw. In my case, that allows even more dust collection because I'd forget to power-on the vacuum. I'm doing a restomod on the miter saw table and this dust collector is like icing on the cake!!
Dana W.
easy replacment, results were night and day, would recomend for any brand
Jackson P.
Love it. 90% or more dust collection!
John F.
Great product. Vey easy to install
Robert L.
It works great. Thank you.
James F.
Works great cuts at least 90% of the dust compared to without it.
Robert S.
It works well! I had put my saw in a small Rockler paint tent with a vacuum on the OEM dust collection tube, so I've never had huge amounts of dust to clean up since most would fall in the tent. But I get much less in the tent now, and I won't have to vacuum out the tent as much anymore.
Rory N.
Works as advertized...
Graham H.
Outstanding bit of kit. Really well designed and fits perfectly. Easy to install and works so well. Thank you for doing this it makes a real difference to home Dudes like me
Phill W.
Arrived quickly, installation was very easy, and it works great! So much better than the factory dust collection. Highly recommended!! Great product.
Tony M.
It leaves more of a mess than I had with the original.
Larry P.
Have used it and it seems to catch most of the chips and dust.
Timothy R.
Huge improvement over the stock dust collection on the DeWalt. I wish I had done this years ago.
ERIC C.
This works great and was very easy to install. The only draw back is it interferes when changing blades, the blade slot should be a little wider.
Christopher H.
Dust collection is great. However the screw that go through the rubber and into the fitting could use a different fastening system. Screw stripped rubber torr almost immediately. I bought small bolts ,nuts , and washers. Seems to be a better option.
Bill
Didnt fit and i did ordered it wrong but cant return it
Steve S.
Super easy to install, and it is far superior to the stock dust collection on my Dewalt DWS779. Well worth the price!
Nicholas S.
easy install and works great!
Charles W.
This made a massive improvement in my miter saw’s dust collection. Well worth the money and a simple installation.
Thomas W.
It does capture more of the dust compared to the oem dust chute.
Ron S.
Fits perfectly and really works well. We’ll worth the small cost.
Jason S.
Was a bit concerned upon receipt as I saw that the housing was 3D printed. But the piece is solid. Scanned the QR code, watched the video and waltzed right through simple assembly steps. It only took a few minutes to complete the swap. Tested with my dust collection rig and am VERY impressed. A great improvement at a reasonable price.
GERARDO G.
This thing is slightly better than the OEM dust shroud; 8 of 10 opposed to 5 of 10... Once you go through the board, the dust gets pushed down, rendering the unit less effective as it moves with the blade. I am still happy with the purchase and would buy it again.
Tim K.
The dust collection system was straightforward to install. It works great in conjunction with an attached vacuum, but not that great when cutting without a vacuum attached (i.e., outdoor workspace). A bit pricey for what it includes.
Zachary R.
Works great! Very impressed !
Kip R.
Great product, fit perfect!!!!
Bobby B.
The well designed dust collectors works very well! Much better than the one that comes with the saw. Well made and the owner's video does a good job of showing how to install. An idea to ease the installation of the rubber part into the channel: add an adhesive to the channel to hold in place when screwing and use slightly larger screw. The 2 outside screws were difficult to get in correctly. Note to user: CHECK YOUR FENCES when pushing the saw back towards them. If too close, they can bend the rubber part a lot. This is NOT an issue with the part but in my case with the user :)
Michel K.
just like the video, perfect fit and explenation.
Marty W.
works great
Collin F.
This was easy to install and is truly an upgrade. The factory only catches about 60% of the sawdust and this one catches 95% of the sawdust .
Kyle D.
The materials seem to be of a good quality, and I think they’ll hold up well over time.
However, I do have have two complaints. There were two flexible rubber dust shoes included, I wish at least one of them had come in a longer size. I can see how a longer one might get caught between the blade and the wood if you’re cutting thicker stock, but I cut a lot of thinner material (3/4” or less) and there is plenty of room for a longer rubber shoe that would (I think) dramatically improve the dust collection. I’m seeing quite a bit of dust escape between the wood and the bottom of the rubber shoe that I think would get sucked up if it were being diverted upward. So my suggestion would be to include different sizes of rubber material and a guide for which one to use depending on the thickness of what is normally being cut.
Second complaint is that when swapping blades the blade has to be pushed against the 3d printed portion and flex out past the arbor to remove the blade. You can still do it, but I think a little more thought could’ve gone into allowing enough clearance for easy blade changes.
Kent K.
Installed in 45 minutes and wow!, what a difference in the amount of dust. So much less and easy to connect the dust collection hose.
Kile W.
Great upgrade from the stock dust collection.
Lindsay G.
Works great. Easy to install.
Jerry W.
Well designed and easy to install.
KOH I.
Works great! Install video was exactly the correct amount of info, no excess or omissions.
JUSTIN C.
Definitely an upgrade to the original dust collector. Very easy to install and has allowed me to bring my work back in the garage without destroying it with dust. Would recommend it to anyone who has the DES780 or DWS779.
Cliff A.
This helps with dust collection so much. I am very impressed. I’d say 75% boost to the poor dust collection of the stock part on the DS-780.
Stephen G.
It fit well and install was easy. I am pleased with how well it collects dust when I use the saw in a chop motion. I am not too pleased when I use the saw out on the rails. The rubber collection piece catches on the saw and hits the blade. I have already ruined the first rubber piece . 2 were included. I may have to see if I can order more.
Doug K.
Fits perfectly on my Dewalt 779. Easy to install and the actual sawdust collection is at least 80 - 90% better than the stock Dewalt system. Shop stays cleaner and I'm not shedding as much "Man Glitter" at the end of the day!
Pete B.
Works great but the amount of emails this website sends is unreal.
Charles F.
Very easy to install. The video was very helpful I like the flexible hose. It makes connections really easy. Well worth the money
Nathan B.
Love the improved dust collection! A lot of functional design and creativity went into building it. I will be back for other products.
Corey
Absolutely recommend this product. Great fit, durable product, works very efficiently and effectively. Would recommend every single time, and already have sang your companies craftsmanship and product. 5 out of 5 stars. No more dusty dewalt dust collection!!!! YES!!!!
Pat G.
Generally really good. However on the 1st test run I had the fence pretty narrow and the saw cut the replaceable rubber funnel. At least 2 came with it and I need to be careful with the fence.
Daniel V.
Don't want to review.
dan k.
just got it installed. great instructions and quality product!
ray k.
The new dust chute did not work any better than the original dust chute for my DW 780.. So, I tried the add on vacuum connection and it work 100% better than anything that I have, So I am always going to use my vacuum anytime I use my DW780 Miter Saw.
William H.
The dust collection system is better than the original DeWalt collector, but in my instance it is not as good as I thought it would be. It works great on straight cuts. On miter cuts and thicker boards there is a lot of dust bounce-back off the rubber “catcher” which makes quite a mess. Overall it is okay, but not great.
Steve H.
Works as advertised. I don’t have sawdust flying everywhere now
Scott W.
easy to install and works great
Stephen K.
Product was easy to install with provided YouTube instructions and dust collection significantly improved.
Rayford M.
installed easily and worked as described very satisfied.
Stephen B.
Very pleased with this kit addition on the Dewalt miter saw. Huge improvement in dust collection. Strongly recommend.
Marty W.
Works Nice
Daniel M.
It really reduced the sawdust flying around compared to the original design.
I really like it and it was easy to install.
Thanks
patrick d.
Worked well until it didn’t. Injection molding failed in two places seemingly simultaneously after about 18 months of very intermittent use. I am a hobbyist that volunteers building sets for a theater company and I build household projects, I use the miter saw maybe a couple times a month. The failure was pretty catastrophic and the rubber skirt got caught up in the blade. Worked well enough I’m coming back to get another one though!
DAVID T.
The order can in on time. The product was so easy to install, with the aid of the video
Danny R.
The item solved my miter saw issue
Douglas W.
Game changer, for sure! I not only have your dust collector on the saw connected to a Shop Vac, but I also have a collection pan under the saw connected to the stand that is hooked up to my shop dust collection system. Whatever isn’t caught at the blade, is caught in the pan and sucked away. 4 Stars!!
Steven M.
Nice design, works much better than OEM, but I wish the collection flow area inside the printed plastic collector was smoother so dust would not collect there. Install was easy and instructions clear.
ROBERT S.
Was a challenge to remove the old parts and install the new one, but it was worth it. The dust is now greatly reduced.
Michael S.
I like the DC mod much more than what came on my Dewalt saw, Im sure I will like it more when I get a chance to hook it up to my dust collector system.
Sanjay D.
Some dust but added a dust collector funnel and that cut dust even more.
Alec P.
Works beautifully! Very quick and easy to install this beauty. Thanks Shop Nation!
Jerry W.
Amazing how much dust collection improves with the kit. 3 days of remodeling rooms with T&G and I was able to clean up the office furniture with a little dusting.
Mike D.
Today was my first time using the saw since I installed the dust collection shield. I'm still seeing more dust than I was expecting to see. I'm aware it was never stated that it would collect all the dust, but I still see a lot of dust collected around the saw but this shield does prevent a lot of the dust from being sent several feet beyond where the saw sits.
Both the amount of saw dust is less and in a much smaller foot print than before.
At this point in time I would recommend buying this it does cut down on amount of saw dust.
Travis L.
I bought this with high hopes that initially were lived up to. Clean up after projects was minimal compared to before and the product worked well. At that point I would've given it 4 or 5 stars. Less than a year after purchase the plastic casing by the blade was cracked significantly where the flap is screwed in (seen in picture). Being that I bought this less than a year ago I reached out to ShopNation about the warranty, and I was informed they only warranty the product for 30 days (which tells me what the company thinks of their own product). To be clear, woodworking is a hobby not a profession for me. I may use my saw for 2 or 3 projects in a couple weeks, then might not touch it again for 2-3 months. My point is I don't put it under strenuous work loads. There is no reason it should have broken this soon with this little use.
Lastly if you are working with trim or boards that have a high vertical under the saw the rubber shield will fold up into your blade, there is no avoiding this. The good thing is they do supply you with a couple, but be prepared to replace often depending on the type of cuts you frequently make.
Tim B.
Great directions and it's a huge improvement in dust collection!
Stephen F.
This dust collection upgrade is well worth the time and money. It dramatically reduces the miter saw dust.
Excellent product!!
Bobby B.
The part and order/shipping/communication were all excellent! The part works well, however, could use a couple of minor tweaks for improvement. I can share those with the creator directly if appropriate.
Richard D.
Simple to install, so much better dust collection. Going to be a much cleaner shop.
David C.
This dust collection accessory is a great and welcome system over what the miter saw comes equipped with, which is hardly worth connecting to a shop vacuum. Helpful instructions available via a QR code were a nice touch, much appreciated.
