Full port and fit detail for this tool
The DeWalt DWS780 is a 12 inch double bevel sliding compound miter saw. The XPS light shows a shadow line so you cut right where you want. A saw this size throws a lot of chips and fine dust with every cut.
The saw has a tapered dust port on the rear. It is not a straight round port, it gets wider toward the lip. Our PETG adapter is shaped to that taper on one end and takes your shop vac hose on the other end. No tape. No clamps.

DeWalt DWS780 Dust Port: What Fits It
The dust port on the DWS780 is tapered, not straight. It gets wider toward the lip. Our adapter is shaped to that taper, so it grips on the slope.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. Neither one fits this port on its own. The dust bag that comes with the saw catches very little, so most chips end up on the floor.
A GulpDust adapter is printed to match the saw taper on one end and your vac hose on the other end. Pick your hose and we make the part to match.
How to Connect a Shop Vac to the DeWalt DWS780 Miter Saw
First, pull the dust bag off and look at the tapered port on the rear of the saw. Wipe out any sawdust so the adapter seats clean.
Press the tool end of the PETG adapter into the tapered port. It is a friction fit, so it grips on the slope with a firm push. Then press your shop vac hose onto the other end.
Turn the vac on before you cut. A miter saw makes big chips fast, so a strong vac keeps the bench and floor clear.
Best Vacuum and Cyclone Setup for the DeWalt DWS780
A miter saw this size throws a high volume of chips. A plain shop vac fills up fast and the filter clogs.
Add a cyclone separator between the saw and the vac. The separator drops the heavy chips into a bucket so your vac filter stays clean and your suction stays strong.
Keep the hose short and straight when you can. Long, kinked hoses cut your suction and let dust settle inside.
DeWalt DWS780 Dust Collection FAQ
Will a GulpDust adapter fit the DeWalt DWS780 dust port?+
Yes. The port is tapered, not straight round, and our adapter is shaped to match that taper. The other end takes your shop vac hose.
Does the DeWalt DWS780 work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose does not match this tapered port. The GulpDust PETG adapter fits the saw port on one end and your vac hose on the other.
Do I need clamps or tape to attach the adapter?+
No. The adapter is a friction fit. You push it into the port and it holds. The same goes for the vac hose end.
Is the small dust bag enough on the DWS780?+
No. The bag catches very little. A shop vac on the port catches far more of the chips and fine dust, which keeps your shop and lungs cleaner.
Do you sell the design file?+
No. We sell the finished part. Each one is printed to order in PETG and ships from the US.
Does the same adapter fit other DeWalt miter saws?+
Sometimes. The DeWalt DWS779 and the DWS713 have close ports, but each saw is a bit different and this one is tapered. Each tool page has the adapter made for that saw.
