What are the different hose diameters for?
The D27 hose works on all tools but the HL850 planer and on all cleaning sets except the Industrial cleaning set. The D36 hose is recommended for the router, planer and cleaning sets but will not work on the sanders or the Industrial cleaning set. The D50 hose is used on the Industrial cleaning set and can be connected with other hose diameters to create a longer hose.
