How much too big are the carbide cutting tools? BTW, yes they are carbide commonly called cemented carbide. It would be a good idea to ask him what grade they are. From that you can find out what material they are designed to cut.
on edit. Actually all you have to do is look at the side of the cutting tools to determine the grade. It should be stamped on and include RH hand or LH.
I recommend making a holder for your quick change tool holder that will hold these tools assuming your friend will continue to supply them. That way you only have one item to mill instead of multiples over time.
