DeWalt DWS779/780 Sliding Miter Saw Dust Collection

Great value, I got what I hoped for. Amazing price, good product. Thank you

Excellent product

Installs easily on the saw. At this time it works fair to good but not a big change in the amount of sawdust. I will try it on a larger full size vacuum to see if there is any improvement. Currently on a smaller shop vacuum. It helps with the larger dust particles but leave a fair amount of fine dust.

Broke my leg haven't used it yet

easy to install and does a better job of collecting dust than the dust collector that came with the DeWalt saw.

Shipping was longer than I expected Must be removed in order to replace the saw blade

Great product. Easy to install and much better dust collection.

it helps but I tore the rubber out by pulling the saw on angle. I would like to buy even bigger sheets of that rubber boot Thank-you charlienaab@gmail.com

Excellent product

So far has done everything it was advertised to do. Easy install. Just a a Hobby Shop so we will see as I do more complicated work with saw and collection over time.

I ordered wrong item

Confirmed this fits an older DWS709

It works great as advertised. Thank you.

fits great

Easy to install and MAN, does it work!! I should have gotten this sooner!! Thank you for a great product!!

Easy installation. Works so much better than the original.

Fits like a glove and looks like it will keep the shop much cleaner!

I purchased your dust collection for my Dewalt 780 it is by far light years better than the stock sytem. I have it connected to my vac and I'm very happy with it. Thanks and keep up the great work.

Great product! I've used on my previous Dewalt saw and recently added it to my new DWS780. Easy to install and the design is very clever. Thank you for keeping my shop cleaner!

The flex tube I managed to get it on the saw part but I cannot get it in the vacuum piece. Vacuum piece is a female, not male like in video and it just won’t go in. I’ve tried needle nose pliers to stretch thru to no avail. Do you have one like in the video with external threads? Also my hose is the same size as the fitting. No adapter acts like a coupling. Please advise. Thank you .

Works great. Thank you

This is a well-designed and nicely constructed kit, and installation was pretty straightforward (though personally I'd really value a non-video option or, barring that, a video that was a bit slower so it'd be easier to pause while working through it - I had to do a lot of scrubbing to get back to my intended place). The main reason I'd only give this three stars is that while it does A TON better than the built-in dust port, it still leaves enough dust that I suspect I'm going to build a dust-collection shroud for my mitre saw, and I'm skeptical that - if I have to do that anyway - this is worth the hassle and purchase.

This dust collection upgrade is exactly what I was looking for. It's greatly reduced the amount of dust left behind after each cut. I highly recommend it!

I have been extremely pleased with the dust collection! The installation was easy and very clear to follow. I would recommend this to anyone that uses a miter saw. Thank you for making a great product!

I used to have tons of sawdust behind, underneath, and all around my saw. I even have a dedicated sawdust collector sitting below it, but it was always a mess. Now the sawdust has been cut to maybe 25%, which is outstanding! Great product and the how-to video was appreciated! BTW, for all the safer officers out there, the clamp is just so I could film.

Fit well and works well, only issue I've encountered is that the two fasteners securing it to the saw must be removed and the unit shifted to the left in order to change the blade. Perhaps some additional blade clearance on the left side would remedy this.

Helps with keeping the dust down.

Easy to install. Did my own test and it definitely grabs more sawdust than the original.

It’s overpriced, it doesn’t work, your return policy sounds great, but it’s moot because once you install it, you can’t return it. Customer service was a bot that kept promising to help, but never did.

This is a great dust collector. We recently mounted a Dewalt miter saw to a bench in our shop and besides not actually collecting dust, the original design limited how far back we could set our saw. This attachment fit perfectly, the mouth of the collector is much larger and we're able to connect our dust vacuum on the top, instead of the rear, of the saw. Besides that, it was delivered quickly once ordered. I'll definitely purchase from them again.

Easy to install and it seems to do a great job

Works great for dust collection!

Pretty good, it has cut the amount of dust from my miter saw down significantly. Small pieces have a habit of getting caught in the chute. I had to take it off to remove the pieces.

This was exactly what I was looking for. This saw is so deep, the factory dust port connection was worthless. Shop Nation came up on my social media and checked it out. He had me in the first 2 minutes of the development video. I love to see fellow engineers coming up with innovative ideas. I dont have mine fully connected to my collection system nearby yet, but I can already tell the improvement in the space. This is a great solution. Installs exactly as the video said.

Easy to install and works as advertized

It is better than Dewalt's at removing dust. If the goal is 100% dust removal and ease of use, I'd like to suggest the following. I have other videos and suggestions I'd like to share. Suggested product improvements. 1. Make the right inside of the dust entrance port/cavity larger/deeper, all the way down to the interior screw mount surface. It's better at removing dust on the left side of the blade. Dust ricochets/bounces out on the right side. 2. The top exterior of dust collector blade channel is too narrow. I couldn't remove the saw blade without loosening/removing the dust collector.

Much cleaner

So far very impressed

Install was a cinch. And I really like the additional room I have compared to the factory version. Has forced me to use my vac system, which I should have been doing all along.

Easy to install, catches about 75% of the dust

Claims of 75% reduction of dust is vastly overstated; I found virtually no difference between this product and the system inherent in the saw which, as claimed by this company is generally very bad. Claims also of easy returns is very misleading. The only way it is easy to return is if you send it back immediately upon receiving it, and then, it still costs you $5.00 and shipping costs. If you install it to see if it does what they claim it does, you cannot receive a refund as it cannot be used or altered in any way so, you can't use it to see if it works; and it doesn't! Lastly, it is terribly overpriced for what it is: worthless! Not happy at all with customer support as well. Buyer beware!

This dust collection system is well made and was easy to install on my DWS779 miter saw. It does allow for shop vac to capture more sawdust than using the OEM collection system. I still use my miter saw tent to capture sawdust that radiates away from chute opening. Glad I made this upgrade to my saw.

awesome!!!

Great product, works as advertised, installs in 15 minutes!

I thought I had just about every possible screwdriver made. However, a T 20 and T 30 driver are not in my collection. I’ve now removed the DeWalt dust collection system, but can’t remove the screws for the next step until I make a run to Home Depot 45 minutes away. For a couple of dollars more, I suggest you add the necessary drivers with your kit or at least give the option to purchase with the unit. I’ll update this when I actually get the dust collection system installed. So I went to Home Depot and purchased the necessary drivers. I have the DeWalt 780. It took an impact driver to remove the 2 T30 screws unlike your video which made it look so easy. The blade guard did not hold the unit in place temporarily. I needed another set of hands. Although you stated that some of the parts may look different than in the video, having the threads on the inside for the back attachment is really poor planning. Very difficult to attach compared to the front where the threads were on the outside. As far as how efficient it is, I’d say maybe a 60 to 70% improvement in dust collection. So not bad, but I wish I was happier. I have a Ridgid vac so I needed to take some extra steps to attach it. See the attached picture. The enclosed extra parts didn’t work with this vacuum.

Wasn't as easy to install as the video showed. It seams to work okay. I haven't used it much yet.

Ordering was easy as was the installation. Works better than expected.

It was quick and easy to install on my DWS709 (scaled-down version of the 779). Install was a little different than the video for the 779 and I installed washers as spacers for the metal arm for the blade guard. Works great. With the vacum hose moved now, being able to put the saw against the wall now is a space savings bonus.

Seems to collect more dust than the factory dust system did. It was a little slow to ship though.

Big improvement!

I appreciate the QR code linked to the easy to follow video. I installed it without a hitch and it works very well with the hose to the shop vac. Very well designed concept and product.

Dust collection works great! Easy to install.

Very easy install, fits and works perfectly. First cut was just like watching a product video, which we all know never happens.

Great Product

Easy install and collects so much mow dust. Definitely a good investment.

Well, everyone knows miter saws are the worst dust producing machines in the shop, your device definitely reduces that dust far better than dewalt’s worthless system, but I was expecting better than it actually performs. I made 3 cuts across a piece of hickory shelving 8 inches by 1 1/2 inches and had significant saw dust in a circle around the machine aft of the fence 20 inches in diameter. The suction hose was connected to a Festool CT 36. All said I’m still satisfied. As I stated at the beginning, short of an enclosed hood, probably not going to get anything better.

Significant improvement. Not perfect but worth the money. The installation video made installation easy.

Install was simple. Haven't tried it out yet but looks like its far superior over stock

Instructions (video via QR Code) was easy to follow and dust collector was not hard to install. Just take your time. It works better than the OEM installed. Adapts to my Fein Turbo II vacuum.

Installed very easily, very pleased

.

Product work excellent, drastically cut the dust distribution. In combination with my cyclone dust collection zero dust. Thanks for the awesome invention.

Nice, better than expected… Wish I can up with the idea..?

Dws780 it mounted to the saw good looks good only tried a couple cuts and worked good. Can’t wait to start a project and put to a true test.

Perfect fit!

Went on just like the video. It is a first.

It isn’t grabbing dust any better than it was before I installed this. I have it hooked to a STRONG vacuum, I have tried my Festool 36 CTE, my shop vac and my dust collector, results were very underwhelming to say the least.

Perfect fit and works very well to reduce the amount of dust in the air. Very happy to have found this product because everything else that we had tried so far did not work.

The part was easy to install, followed the instructions video makes it easy for anyone. I haven’t had the opportunity to utilize it with my dust collection system but that will happen soon. It’s the first part of my dust collection system, that is in the building mode.

Good service. The item i need. Thx!

Easy installation. Works great!

I will not be purchasing anything else, ever, from you guys. I asked yall a question regarding the install and crickets.... noone said a word. Service after the sale is important to me.

Works much better than the original!

Way better than the stock set up and my wet/dry vac coupled with a 20x20 inch box fan and furnace filter behind the saw. I also purchased the Inspire Woodcraft zero clearance throat plate. I hope its not overkill. I still plan on using the fan w/filter, just relocating it. I realize that I will have to swap out the zero clearance throat plate in order to make bevel cuts but that should be rare. I really appreciate the fact that my shop will be much cleaner as well as a healthier place to hang out.

Meh…not as effective as I had hoped, and not much improvement over the existing set up (dust hood with 4” down outlet to 2.5” hose.) Already cut the rubber skirt twice. Would not buy again - the hype didn’t deliver the help in my scenario.

Easy installation.

Although it’s better than the stock set up it’s not a “huge” difference as others have mentioned. Not sure I would have paid 50$ for it if I’d known the outcome. I will say, if you had made the dust boot much bigger, this would work a lot better.

I have been following your channel almost since day 1. I watched all the segments on your development process of the Miter Saw Dust Collection (I too am a recovering Engineer ). I built a mobile folding arm miter saw station with a 10" fixed Saw but wanted to wait till I upgraded to purchase the dust collector. I recently purchased a new Dewalt 780 Sliding Miter Saw and ordered the Duat Collector the same day, I cut a few pieces prior to the new parts arrival and spewed dust everywhere in my basement (I live in Michigan too cold outside) - Installed the new dust collector parts upon arrival and very pleased. Is it 100% dust free No didn't expect it to be. Is it a 95% dust collecting improvement Absolutely! Love this upgrade!! Dust is limited and not spewing all over

At first I had trouble figuring out “how” the dust shoot connected, but your Customer Service and Tech Support team were helpful. Everything fit nicely and works better than both the factory dust collection system and my DIY modifications.

Fits great and works great!!

Went on my saw perfectly in a very short time. Hooked it up and although it didn't get all the saw dust but it got a lot more than I really exspect. I am just elated with the dust collection which helped my clean up time greatly.

Why did I wait! Installation was a breeze following the video. Works better than expected. Saved me so much time cleaning up and, due to size constraints in my small shop, can keep it closer to the wall. Gets 98% of the saw dust. Very happy with this purchase!!

I wonder if I can swear? Because oh boyhowdy I swear this dust thing works great!!! Bitches

Upside: 1. Install is easy, 3 bolts and 2 zip ties. 2. If using a vacuum / dust collector then this is a very good upgrade. Does good “pre-work” for those that are neat freaks. Downside: 1. No install instructions, must watch a video on YouTube. Inconvenience if you “disconnect” in your workshop like me. 2. After installing, you must use a vacuum or dust collector, otherwise you will get more build up than OEM collection point when cutting. Overall, good value, easy install, major upsides, minor downsides.

great product and helpful installation video

New saw to me and have it calibrated yet the “factory” dust collector did not work. I had a hard time getting one of the original screws out and I had to spread the fence to allow the new dust collector to work with no interference. Yet, the fence probably was supposed to be set anyway. Works great! My shop vacuum slides right in with no adapters. Great product.

It Sucks!!!! Exactly how the OEM system should have. Dewalt fell short when the created that vented tube of an excuse. This is a simple design that looks OEM and functions above expectations.

As advertised, works great and at least 80% reduction in blow back saw dust. Couldn’t be happier.

Game changer

Was as expected works great

After many years of dust, dust, dust, this was truely a welcome improvement. Although coming from a plastic molding company, I am sure that the purchase is roughly 75% profit for the seller.

I don’t think I’ll need to build a hood now as it works great!

I haven't had the chance to install it yet but it looks like it is very durable and should work just fine. I do not have a heated shop and it has been really cold here.

It was easy to install. And when I had an issue, customer service was great.

I was disappointed in the quality of the 3D printing. And no instructions that the attachment to the flex hose was reverse threaded.

I watched the install video and proceeded. Removing the OEM dust collector was more difficult than shown in the video, but once removed, the installation was very simple. I bought the extension hose and am able to hook it up to my Dust rite collector. Well engineered, perfect fit.

Second time I had to purchase after a long wait from the first purchase due to frustration and unit seemed brittle and did not hold up after 5-10 uses. Took a shot and repurchased and this time it's perfect and as advertised.

After testing, the out of the box collection port on the saw hooked up to a dust collector works better than this. The inlet hole is smaller than the Dewalt inlet so that might be the issue.

Simple to install. Most certainly collects far more dust than the original!

Doesn't seem to work any better than the DeWalt version.
