Jigsaws are tricky for dust collection. Unlike a circular saw where the blade throws chips backward, a jigsaw's blade moves up and down. The cut zone is open at the front. Dust blows forward, upward, and sideways all at once.
A dust port on a jigsaw does not capture everything. But it captures most of it. The difference between using a shop vac hookup and not using one is significant.
Where the Dust Port Is on a Jigsaw
Most jigsaws have a small round port at the rear of the tool body, near the blade clamp. It is typically smaller than the port on a circular saw. The size changes with the brand, and every one we cover has a page on the port size hubs.
Some jigsaws also have a front blower nozzle that blows dust away from the cut line so you can see the line. This blower does not connect to a vac. It is separate from the dust extraction port.

Find your jigsaw on the port size hubs and the adapter follows from there.
What Shop Vac to Use with a Jigsaw
Any shop vac with a 1-7/8 inch (47.6mm) hose will work. You need an adapter that goes from the jigsaw's port to the vac hose. The jigsaw port is smaller, so the adapter reduces down.
If you run a cordless system, a small cordless vac is ideal. The Milwaukee M18 FUEL 0882-20 drops straight onto a Milwaukee jigsaw. The DeWalt DCV517B uses a 1-1/4 inch hose and needs a tool-side adapter.
A Festool PS 300 EQ works best with a Festool CT MINI or CT MIDI. The 27mm Plug-it hose connects directly to the tool. No adapter is needed within the Festool system.
Tips for Better Jigsaw Dust Capture
Keep the base plate tight against the workpiece. Gaps under the base let dust escape before the port can catch it.
Use a steady cutting speed. Racing through the cut throws more chips. A controlled feed rate keeps dust in the port zone.
For dusty cuts in MDF or plywood, wear a respirator even with a shop vac. A jigsaw port captures 60 to 70 percent of total dust, not 100 percent.
If your jigsaw has a blower nozzle, turn it off or minimize it. The blower pushes dust away from the cut line, which helps you see the line, but it also blows dust away from the extraction port.
Corded vs. Cordless Jigsaws for Dust Collection
Corded jigsaws often share a port size with their cordless twins. The Bosch JS572EB (corded) matches the Bosch GST18V-LI (cordless). The Milwaukee 6268-21 (corded) matches the 2737-20 M18 FUEL. Both pairs show up together on the port size hubs.
This matters because your adapter for a corded saw will also fit the cordless version of the same brand. You do not need two adapters.
Installing the Adapter
Push the adapter into the jigsaw port. It should be snug but not require force. Then push your shop vac hose into the other end of the adapter.
With the vac running, make a short test cut. Hold your hand near the cut line. You should feel almost no airflow escaping from the cut zone. If you feel strong airflow, the connection is leaking.
