M18 Random Orbital Sander Vacuum Adapters

Milwaukee M18 Random Orbital Sander Direct Hose Adapter

Description

Update: I now have an M18 sander to the Festool 36 mm (1.4″) vacuum hose. Thanks to Bill McLean for asking about and testing the new stl file.

M18 Sander to Festool Hose

I have posted several adapters to connect to the dust post of the Milwaukee M18 Random Orbital Sander (model 2648-20). These adapters were created in Fusion 360, so unfortunately I cannot share any useful models.

I have included 3 different STL files:

Milwaukee M18 Random Orbital Sander 1_375 inch Left-Hand Wrap Hose Adapter
1-3/8″ Left-hand Wrap Hose Adapter
Milwaukee M18 Random Orbital Sander Indirect Hose Adapter
M18 Compact Vacuum (1-5/8″ Left-hand Wrap Hose) Adapter
Milwaukee M18 Random Orbital Sander Direct Hose Adapter
M18 Compact Vacuum (1-5/8″ Left-hand Wrap Hose) Direct Connector

Files

Printer: Prusa i3 MK3
Slicer: Cura Slicer
Material: Inland PET-G
Resolution: 0.2mm with a 0.4mm nozzle
Wall Lines/Perimeters: 3
Infill: Minimum 10% Gyroid. The higher infill percentage the stronger the part.
Notes: No supports should be necessary.

Instructions

To attach these adapters to the M18 compact vacuum hose, you need to remove the nozzle. The hose is left-handed, which means the wire is wound in a left-handed direction, opposite of the normal right-hand direction that you are used to with most threads.

M18 Compact Vacuum Hose Nozzle

To remove the nozzle, turn it clockwise until the glue breaks, then the nozzle will screw off. Then screw the new adapter onto the hose counter-clockwise.

  1. Nice Job, I printed the direct connect file hoping it might fit on my Festool hose. it does not, a little too big, but the sander side is perfect. any chance you would modify the file to have a smooth inside round end with a ID of 1.4 inch.

  2. Wondering if you would be willing to send over a file to hook up directly too the Milwaukee wet vac hose without having to screw it on.

    Thanks

    1. That black adapter that comes with the sander shown in some of the photos above should work. It works with my M18 lunchbox vacuum (the not Packout wet/dry vac).

      1. Are you talking one of the adapters you posted? My orbital sander did not come with a black adapter. I did measure the outside diameter of the nozzle that is connected directly to the wet dry vacuum and it’s 32.8mm or 1.291″.
