DEWALT Circular Saw Dust Collection Adapter, DWE575/DWE575SB Compatible (DWE575DC), Black

Fits a dcs590 perfectly and does a good job collecting dust.

Does a decent job keeping sawdust at bay. Doesn’t catch everything with the open circular saw as you’d expect. Fitment was great on my dewalt saw. Vacuum hose fits right up to it as well.

A bit expensive and is a bit difficult to install .. Appears to work reasonably well but not perfect.

I bought both the DCS578 (Type 1) and this adaptor in Dec 2022. This adaptor went on the saw like...well, like it was made for it.No cuttingNo grindingNo screwing it together before putting it onNo need for an offset screwdriver eitherPerhaps the other reviewer didn't have the hand strength to squeeze the front and back halves together and hold them as he put the screws in. We'll never know.Put the back half on first, hooking the notch onto the bottom rear as the directions state (you're going to read the directions, right? Just don't let anyone see you doing it).Then put the front half in place. The front half doesn't exactly match the saw until the screws are tight, I guess that helps keep it firmly in place once correctly installed without hacking it up.Squeeze the adaptor together as you put the screws in. When the screw are a few turns in, they get tight, and there's a 1/6"-1/8" gap between the 2 halves. I guess that can make some people think it won't fit, but fear not my friends!Gather some inner fortitude and maybe a 1/4" impact driver with a phillips bit (that's what I used) and drive the front screw in. Now don't go nuts on it, just screw it in until the 2 halves touch together. Any more than that and you'll crack it, wasting 12 hard earned dollars.The back screw has to be screwed in on a angle. I happen to have a 6" long phillips bit for my impact, so I used that and went slow so it didn't strip out the head of the screw. If you don't have a long phillips bit that'll work, sucks to be you. You just spent $12 for a dust adaptor you don't need, why didn't you waste a few bucks on some long 1/4" bits for your impact? Up to you on how you're going to tighten it, I'm just leading you to the water.They also give you a new lower guard handle and screw. It's offset (bends outward, away from the adaptor), I guess other saws have a straight lower guard handle. My saw already had the exact same offset handle and exact same size (length) screw they provided with the adaptor, so you know what I did? I removed the brand spanky offset handle and screw from my brand spanky saw and replaced it with the exact same brand spanky handle and screw included with the adaptor.I'm going hang onto the original handle/screw so if the day ever comes that I bend or break the handle on the saw, I'll have no idea where the original parts are and will never find them.

Having a dust collection port on my circular saw is very good thing. This really captures the sawdust from the blade. It can't imagine not having this now. I'm not covered in dust when I use my circular saw.

I hope this finds all 2021 and 2022 Dewalt Flexvolt 60V 7-1/4" circular saw (DCS578) owners looking to buy this product.UPDATE: I took a dremel to it and got it to fit. It's a simple cut/grind it to match the curvature of the upper blade guard. Attaching it to the actual blade guard is a bit of a pain. You have to screw the sides together before installation unless you have a very short offset phillips. There's less room than a standard 1/4" hex bit's length. The screw by the dust port needs to be fully screwed in and the further one half screwed in. Spread it apart wide enough to get the pin and the dust port tab to seat and press it down. Then finish screwing in the upper screw. It ends up being a secure fit and don't forsee it moving.The Dewalt DWE575DC at some point in time must've fit the DCS578. I know this based on the older reviews as well as the shape of the product pictures. I received one with a code of "2021 19-47-52". So at some point Dewalt had redesigned the product without changing the product number.As you can see in my pictures, there is a major change in the back plate vs the product pictures. The tab style as well as the flaring has changed. Because of these changes, it does not fit the DCS578. The tab location has been moved and will interfere with the gear case assembly. The old style back plate also had a flare that followed the contour of the gear case. It also has a tighter curvature to it which interferes.For the cost of $11, I think I'll try taking a dremel to it. I will lose the tab and rely on the front pin and the 2 housing screws to hold it onto the saw.

Exactamente como lo espereraba

LONG STORY SHORT:When looking for a dust collection adapter for my "DEWALT 20V MAX 7-1/4-Inch Circular Saw with Brake, Tool Only, Cordless (DCS570B)" it was really difficult to figure out IF there was even adapter for it. THIS ADAPTER FITS even if it's not listed as one of the saw options in the description. Works great!PROS:-Fits perfectly on my DCS570B circular saw. No issues, gaps, jerry rigging....it was made for this saw as well, it's just not listed as one of them.-Ribbing/Ridges on the back of the port connect great with my Cen-Tec adapter system (as shown in photo). Holds them on tight.-Side port allows for dust to shoot downward instead of backward...if not using dust collection. Making the saw still function as originally designed.CONS:-Figuring out what (IF ANY) dust collection adapter would work with my DeWALT circular saw was a chore. It's not listed as one of the "options" in this description, nor is Dewalt's website helpful in the matter. I had to make an educated guess based on information I'd seen...and it worked out.-I wish there was a little sliding door on the side vent, so you could close it, when you're connected to a dust collection system. Not that it really seems to make a big difference, but it's hard to tell, and would be a nice option. However...any moving parts and pieces are liable to break...which is probably why they didn't bother.CONCLUSION:Buy. Fits perfectly on my DeWALT cordless DCS570B circular saw, and is incredibly effective (with my Cen-Tec system) in greatly reducing the amount of dust in my woodshop.
