Connect a Bosch CM10GD miter saw port to a Festool D32/22 antistatic hose
How to join a Bosch CM10GD miter saw port to a Festool D32/22 antistatic hose, and what stops it leaking dust.
Not a direct fit. Joining the Bosch CM10GD miter saw port to a Festool D32/22 antistatic hose needs a 1-1/4 in to 22 mm step reducer.

Shop notes
Measured across the joint between the Bosch CM10GD miter saw port and the Festool D32/22 antistatic hose, the port socket (32 mm) is 10 mm larger than the hose tip (22 mm), so the hose tip rattles inside without gripping. A 1-1/4 in to 22 mm step reducer closes that 10 mm step so the two hold together instead of leaking at the gap.
A 10 mm mismatch feels close enough to force, and it will hold for a minute before it works loose under airflow. Fit the step ring rather than trusting friction on a gap this size.
