Hey everyone! I'm trying to find out the exact spline size for the Milwaukee Quik-Lok system. I inherited a Ryobi power head with some attachments, but I really want to stick with my Milwaukee tools. I've heard that the Ryobi attachments are decent, but I'd rather not buy new ones if I can avoid it. I think I heard it might be a 7-tooth spline, but I want to confirm the exact size since I can't measure it myself. Also, if anyone knows the shaft diameter in metric, that would be super helpful! Thanks!

It’s confirmed to be a 7-spline system, and the size is approximately 7mm. I just took a measurement with a caliper to double-check!
Thanks a ton for confirming! Any chance you could also measure the outer shaft diameter for us?
Make sure to keep us updated! I'm in the same boat, as I have a bunch of Echo attachments I might want to adapt. Let us know what you find out!
Will do! I plan on updating this thread with what I buy and any modifications I make.
I was about to measure mine too, but you got to it first!
