This is a osVAC M32 adapter for the Einhell TE-OS 18/1 oscillating sander. It is secured with 3 screws. The inner diameter is 28.8 mm, maybe it fits on similar tools.
You'll also need:
I recommend to first drill holes for the screws with a 1 mm or 1.5 mm drill before screwing the screws in.
To attach it with a installed o ring, i needed to chamfer the edge of the output pipe of the sander with a cutter knife a little bit. Then use quite a good amount of force to push it in.
The last photo shows it with the dust collector of the Bosch GEX 12V-125 attached. The power of osVAC. :)
The Model is based on the great osVAC neo project by TOKENIZER.
