Shop notes

The port measures about 36 mm and the hose about 35 mm, only 1 mm apart, so the port seats inside the hose as a friction fit. No reducer is needed for this pairing, so the Festool KAPEX KS 120 miter saw port and the Bosch VAC024 35 mm hose connect directly.

It is a push fit, not a lock. Seat it fully and check it has not crept loose after a few minutes of vibration before you trust it on fine dust.
