Shop notes
The port measures about 27 mm and the hose about 28 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 Bosch 27 mm tool port and the Makita 28 mm anti-static 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.
