I'm looking to create a slot for a fastener to allow movement, I can't find an end mill with the proper 41 degree chamfer (82 deg fasteners heads). I've tested using our 1" shanked countersink for these short slots and have success cutting with these in Aluminum and Brass. I'm being challenged now by management doing this due to an operator error and the question come to why we are doing it this way. I've machined slots this way with slow feed rates with no issues, wanted to see if anyone else have done the same before. These slots are 2" long.
It is fine that it appears here but I was surprised to see it. I notified my tool maker and he will be happy to get a call. Good luck Bryan.
