Bosch makes cordless and corded tools in many lines. Tool makers change port sizes between models, and a tool port may not match the size of a US shop vac hose. Do not trust a chart. Measure the port on the tool you own.
Measure Your Bosch Tool
- Look at the dust port. Is it an opening, or a stub?
- If it is an opening, measure across the inside with calipers or a ruler. If it is a stub, measure across the outside.
- Measure the end of your hose the same way.
Give us the two numbers and we print the adapter to them. The size guide shows how. You can also see our Bosch page. For a starting point, the 35mm size page shows what we print at that size.
Bosch to a Standard Shop Vac
The end of a small shop vac hose may be too small to seat in a tool port. An adapter takes the port to the hose end. It seats in the tool port on one end and grips the hose on the other. If your shop vac has a larger hose, the part is printed to that hose end instead. Measure the one you own.
Bosch to a Festool Extractor
The Festool hose end may be smaller than your tool port, so the adapter steps down to meet it. This is a common cross-brand setup: Festool extractors are popular and plenty of shops run Bosch tools.
Suction from a mid-size Festool extractor is good enough for sanding, routing, and circular saw work.
Bosch Dust Extractors
Bosch also makes dust extractors. Even if the tool and the extractor are both Bosch, measure both ends. Do not assume the two share a size until you have checked.
Connecting to a Central Dust Collector
If you have a fixed dust collection system with 4-inch duct, you will step down a long way to reach a hand tool. The best approach is a reducer at the duct drop, then a flexible shop vac hose to the tool with an adapter at the tool end. Measure each connection and print to those numbers.
Other Brands in a Mixed Shop
If your shop mixes brands, measure each tool separately. Two brands can look the same and still differ by a few millimeters.
