DeWalt DCS355B Oscillating Multi-Tool Dust Port Size and Vacuum Adapter Guide
The DeWalt DCS355B is the 20V MAX oscillating multi-tool. It runs on the DeWalt 20V battery and cuts, sands, and scrapes in tight spots. The blade makes fine dust right where you are working.
The tool has a dust port on the front, and it is a proprietary shape. DeWalt sells its own dust shroud for it, and there is no confirmed aftermarket size yet. So measure your own port with calipers before you buy. A GulpDust PETG adapter is sized to your port on one end and your shop vac hose on the other end. No tape. No clamps.

DeWalt DCS355B Dust Port Size: Proprietary Shape, Measure to Confirm
The dust port on the DCS355B is a proprietary shape, not a clean round port. DeWalt makes its own dust shroud for this tool, and there is no confirmed aftermarket size yet. So the safest path is to measure your own port.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. They do not fit a small tool port like this on their own. That gap is why dust drifts up into your face as you cut.
A GulpDust adapter is printed to match your tool port on one end and your vac hose on the other end. Measure your port first so you order the size that seals tight.
How to Measure Your DeWalt DCS355B Dust Port
Look at the front port on the tool. Because it is a proprietary shape, write down more than one number. Wipe out any dust so your reading is clean.
Close caliper jaws around the OUTSIDE of the port at its widest point. Then take the inner reading the same way. Note the width and the height if the port is not round. Those numbers tell us the shape so the adapter can be matched to it.
How to Connect a Shop Vac to the DeWalt DCS355B Multi-Tool
First, look at the front port on the tool. Wipe out any dust so the adapter seats clean.
Press the small end of the PETG adapter onto the port. It is a friction fit, so it holds with a firm push. Then press your shop vac hose onto the other end.
Turn the vac on before you start. A clear cut line helps you stay on the mark in tight spots.
Why Dust Collection Matters on the DeWalt DCS355B
A multi-tool often works up close to your face, at eye level on walls and trim. The fine dust it makes goes right where you breathe.
Pulling that dust at the port keeps it out of the air and off your work. You see the line and you breathe clean.
Any shop vac works. Keep the hose light and out of the way so the tool stays easy to steer in tight spots.
DeWalt DCS355B Dust Collection FAQ
What size is the dust port on the DeWalt DCS355B?+
The port is a proprietary shape with no confirmed aftermarket size yet. DeWalt makes its own dust shroud for it. Measure your own port with calipers before you buy.
Does the DeWalt DCS355B work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose is too big for this small proprietary port. The GulpDust PETG adapter fits the tool port on one end and your vac hose on the other. Measure your port first so the fit is tight.
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.
Can I print this adapter myself?+
Yes. You can buy the printed PETG part shipped from the US, or download the STL file and print it at home. We suggest PETG with 3 walls and 25 percent infill.
Does the same adapter fit other DeWalt 20V MAX tools?+
Not always. DeWalt 20V MAX tools use different ports. The multi-tool and the jig saw use proprietary shapes, while the DCW600B router has a verified round port. Check each tool page for its verified port size before you buy.
