I have a few mills that take NMTB-50 tool holders. Obviously changing tool holders there is a PITA. I also have many Universal Engineering Kwik-Switch 300 tool holders I bought for a Bridgeport mill that never arrived. I’d love to be able to use the Kwik Switch holders in an NMTB-50male/Kwik Switch 300 female If I could find such an animal. Were any made?

A more involved project would be somehow adapting a Kwik-Switch 300 spindle to NMTB-50 outside profile. Those spindles are available. Here’s one so u can see profile. Does that look feasible?

search the for sale posts for Kwik switch 200 spindles. They are miss identified, and are actually Kwik switch 300 spindles. have the bearing diameter ground to a common end Mill size and then run them in an end Mill holder.
 
I've got at least one 50 to 300 with maybe 20 holders I'd take $500.00 for all of it. There's some collets in there too
