Milwaukee 2648-20 M18 Sander Dust Port Size and Vacuum Adapter Guide
The Milwaukee 2648-20 is the M18 5 inch random orbit sander. It runs on the M18 battery and smooths wood and metal fast. A sander like this makes very fine dust, the kind that floats in the air.
The sander does not use a clean round port. It uses a proprietary collar built into the dust outlet. There is no confirmed aftermarket size for it yet, so measure your own collar with calipers before you buy. A GulpDust PETG adapter is sized to your collar on one end and your shop vac hose on the other end. No tape. No clamps.

Milwaukee 2648-20 Dust Port: A Proprietary Collar, Measure It
The 2648-20 does not have a plain round port you can size at a glance. It uses a proprietary collar built into the sander. There is no confirmed aftermarket size for it yet, so do not trust a guessed number.
Community adapters exist that bridge this collar to a shop vac hose. They work, but they do not publish a verified tool-side size. Measure your own collar and order to that.
A GulpDust adapter is printed to match your collar on one end and your vac hose on the other end. Measure first so the adapter seats clean and seals both sides.
How to Measure Your Milwaukee 2648-20 Dust Collar
Close caliper jaws around the OUTSIDE of the collar. That gives you the outer diameter in millimeters. Round to the nearest standard size if your number falls between two.
Next, slide the inside jaws into the collar and open them out until they touch the inner wall. That gives you the inner diameter. The inner is what the adapter slides into; the outer tells you how snug the fit will be.
How to Connect a Shop Vac to the M18 5 Inch Sander
First, clear any dust out of the collar. A clean collar gives the best seal.
Press the small end of the PETG adapter onto the collar. 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 sanding. Dust collection on a sander is not just about a clean bench. Fine sanding dust is the kind that hangs in the air and gets into your lungs.
Why Dust Collection Matters on a Random Orbit Sander
A random orbit sander makes very fine dust. That dust floats. It does not fall to the floor like saw chips do.
Pulling that dust at the port keeps it out of the air. It also keeps the pad clean, which helps your sandpaper last longer and cut better.
For the smoothest finish, run a steady vac while you sand. Any shop vac with the right adapter does the main job.
Milwaukee 2648-20 Dust Collection FAQ
What size is the dust port on the Milwaukee 2648-20?+
The sander uses a proprietary collar, not a clean round port. There is no confirmed aftermarket size for it yet, so we will not guess one here. Measure your own collar with calipers before you buy an adapter.
Does the Milwaukee 2648-20 work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose does not seal on the sander collar on its own. The GulpDust PETG adapter fits your collar on one end and your vac hose on the other, once you measure it.
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.
Why does this sander need dust collection so much?+
Sanders make very fine dust that floats in the air. That dust is the kind that is bad to breathe. Pulling it at the port keeps the air clean and helps the sandpaper last longer.
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 Milwaukee M18 tools?+
Not always. Milwaukee M18 tools use different dust outlets. This sander uses a proprietary collar, the jig saw uses its own shroud, and the circular saws use a round port. None of these sizes are confirmed yet, so check each tool page and measure before you buy.
