M18 Oscillating Tool (OMT) blade adapter


Recommended Posts

I recently purchased a Milwaukee M18 oscillating tool, and  since this is my fifth OMT and the first cordless one, I rounded all my OMT blades from over the years and see if they all fit on this OMT and I am having trouble with those made by Rockwell, I think they are often referred to as "First generation" or "original" Rockwell blades.  These blades have a 12 sided star shaped mounting hole.




In referring to Milwaukee's own user manual, there is an adapter for it, and I have this adapter.








This is the OMT with the adapter added.  You can tell the adapter is exactly the one in the manual.




I then tried to put some blades on it, and the fitment is poor and loose.






Is the Milwaukee documentation wrong, or is there another adapter for these blades?


Thank you.

Just a quick follow up, I also contacted Milwaukee's customer support and their reply was the adapter I need is part number 48-03-2526.  This is the adapter I have already, so not sure why they would suggest that to buy an additional wrong adapter.

So now I am on this back and forth with Milwaukee customer service and I would like some suggestion on how to get to someone on Milwaukee's side that is technical enough to understand my question.


My first inquiry to their customer service / technical support is via their online contact form.  I basically include everything I typed in the first post, with detail explanation and pictures.


The first reply I got back after a few days is to get part number 48-03-2526.


So it appears they did not even read my email carefully. I replied back and said 48-03-2526 is indeed the adapter I have in my hand, and the adapter I showed in the pictures, the adapter that is not working, and the adapter referenced in the user manual whose picture I also included.


The second reply was "can you send us pictures of what you have?"  So I sent in the pictures again, of the OMT, the adapter, the blades I have, and the fitment issue, all of those were in the original inquiry.


The third reply was I need to buy part number 48-90-0000 and that is the adapter I need.  I called around locally and one Ace hardware has it in stock.  I went there and bought it and it didn't even fit on the M18 OMT.  I then did a search and even on Milwaukee's own site it says that the 48-90-0000 "The Milwaukee Multi-Tool Adaptor allows for all Milwaukee Multi-Tool Blades to be used with Porter Cable, Black & Decker, and DeWalt brand multi-tools" so it's designed to allow mounting of Milwaukke brand blades onto other OMTs, not an adapter to fit other brand blades onto the M18 OMT.


I replied back to Milwaukee that this didn't work.  But I guess I cannot rely on Milwaukee's CS to help solve the problem they either didn't understand what I was asking or worse yet didn't care about wasting my time.  I don't know if there is another department like product engineering or whatever that may know the answer but so far Milwaukee hasn't been helpful at all.

BUMP.  Anyone knows if there is a way to escalate my support request since the general support staff seems not equipped to handle my question (or fully understand what I asked) as they kept asking me for pictures of this and that, information and pictures that were submitted with the initial inquiry.
