3/8 dovetail end mill angle

[Killitgrillit]

Howdy all
Yes I'am going to cheat and use a mill to cut some dovetails.
Question is what is the most commonly used angle I've seen mills listed that where 45deg and 60deg.
anyone?????
Thx Killit

60 deg., same as a triangle file...

At the same time I would cut one in some scrape metal. To make sure that you will get the fit that you want. Or a lot of VERY carefull measuring.
