Shop notes
Found on: Bosch sanders, multi-tools and compact tools built to the 27 mm extraction connection.
Bosch splits its extraction line at 27 mm for small tools and 35 mm for larger ones. The 27 mm port takes a 27 mm hose or steps up to 35 mm, and because 27 mm matches the Festool D27 tip it crosses to Festool hoses too.
