The Milwaukee 2731-20 is the M18 FUEL 6-1/2 inch circular saw. It cuts fast and runs on the M18 battery. Like most cordless saws, it throws a lot of sawdust when you cut.
The saw has a round AirLock-style dust port on the rear. Our adapter fits it. A GulpDust PETG adapter is sized to the port on one end and your shop vac hose on the other end. No tape. No clamps.

Milwaukee 2731-20 Dust Port: What Fits It
The dust port on the 2731-20 is round and sits on the rear of the saw. It is an AirLock-style port, and our adapter is printed to fit it.
Dust pickup matters on a circular saw because the chips spray out the back and cover your line. When the line is buried, the cut wanders. A vac at the port pulls those chips away so you can follow the mark.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. They rarely match a saw port on their own. A GulpDust adapter is printed to match the saw port on one end and your vac hose on the other end.
How to Connect a Shop Vac to the M18 FUEL 6-1/2 Inch Circular Saw
First, look at the rear port on the saw. Wipe out any sawdust so the adapter seats clean.
Press the tool 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 cut. Let it run for a second after each cut so the hose clears. This setup catches most of the dust at the blade instead of on your bench.
Best Vacuum and Dust Extractor Setup for the Milwaukee 2731-20
Any shop vac works. A vac with an auto-start outlet is even better, because it turns on when the saw turns on. You do not have to remember to flip a switch.
If you cut a lot, 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 longer.
Keep the hose short and straight when you can. Long, kinked hoses cut your suction and let dust settle inside.
Milwaukee 2731-20 Dust Collection FAQ
What size is the dust port on the Milwaukee 2731-20?+
It is a round AirLock-style port at the rear of the saw. Our adapter is built to fit it. You pick the hose end you need.
Does the Milwaukee 2731-20 work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose does not seal on the saw port on its own. The GulpDust PETG adapter is sized to the saw port on one end and to 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.
Will dust collection slow down the saw?+
No. The adapter only routes the dust the saw already makes. It does not touch the blade or the motor. The saw still spins at 5,000 RPM.
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 Milwaukee M18 tools?+
No. Milwaukee M18 tools use different dust outlets. This saw uses a round port, the jig saw uses its own shroud, and the 5 inch sander uses a proprietary collar. Each tool page shows the adapter that fits it.
