Milwaukee built the M18 platform with dust extraction in mind. Most M18 FUEL tools share one dust port, and it sits on the 1-1/4 in. port hub. That is close to most standard shop vac hoses. In theory you can plug your shop vac hose directly into the tool.
In practice, the port geometry rarely matches the hose exactly. The hose end may be too loose or too stiff. The adapter solves this by matching the port ID on the tool side and the hose OD on the vacuum side.
M18 Tools With Dust Ports
Here are the M18 FUEL tools with integrated dust collection:
| Tool | Model |
|---|---|
| Circular Saw | 2731, 2732, 2737 |
| Rear Handle Circular Saw | 2830 |
| Jig Saw | 2737 |
| Random Orbit Sander | 2648 |
| Detail Sander | 2570 |
| Oscillating Multi-Tool | 2836 |
| Compact Router | 2723 |
Every tool on that list lands on the 1-1/4 in. port hub. One adapter covers all of them.
Shop Vac Compatibility
A standard shop vac with a 1-1/4 inch hose connects directly to most M18 tools. The most common small-end hose sizes are:
- 1-1/4 inch: most 2.5 to 6 gallon shop vacs; fits M18 ports directly with a light adapter
- 1-7/8 inch: most 8 to 16 gallon shop vacs; needs a reducer to match M18 ports
- 2-1/2 inch: central dust collection and large extractors; needs a reducer
Festool and Bosch Extractor Compatibility
Many serious Milwaukee users run their M18 tools on a Festool CT or Bosch VAC extractor. The hose adapters for these extractors are not the same as shop vac hoses. Festool CT hoses use a 27mm hose end. Bosch VAC hoses use 35mm.
To connect an M18 tool to a Festool CT hose (27mm): use the reducer built for the 1-1/4 in. port hub on the tool side.
To connect an M18 tool to a Bosch VAC hose (35mm): use the step-up built for the 1-1/4 in. port hub on the tool side.
The M18 FUEL Drywall Cut-Out Tool
The M18 FUEL drywall cut-out tool (2627) is a special case. It has a shroud that connects around the bit opening, similar to a router. The shroud itself needs to attach to the tool before you can connect the hose. Milwaukee includes a basic shroud with the tool. Third-party PETG shroud extensions are available for longer bit reach.
How to Get the Best Capture Rate
Three things affect how well dust collection works on M18 tools:
- Filter quality. Standard shop vac filters blow fine wood dust back out. Use a HEPA filter bag inside your shop vac.
- Hose length. Every extra foot of hose reduces suction. Keep the hose as short as practical. Coiled hose is worse than straight hose of the same length.
- Adapter fit. A loose adapter pulls in ambient air instead of drawing dust from the port. The adapter should friction-fit snugly with no wobble.
M12 Dust Collection
Milwaukee M12 compact tools are smaller and have smaller ports. Most M12 cutting tools do not have a built-in dust port. A few M12 multi-tools and sanders have a port, and it is smaller than the M18 one. These need a different adapter than M18 tools.
