Shop notes

Found on: Fein oscillating and compact tools built to the 30 mm connection.

Fein small tool ports are 30 mm, a hair smaller than the Bosch 35 mm standard, which is why a Bosch or generic 35 mm cuff does not grip a Fein port without a step. The Fein Turbo hose itself is 35 mm at the vac end.
