I need a 3" radius end mill based on a 1.1875 or 1.25 (1" shank) end mill. My tool maker that normally does the work tried to put a 3" radius on a 1.1875 cutter and can't do it. Can someone tell me who might could handle this for me? My tool maker said he had gone totally to CNC for his grinding and he could get the machine to do that large a radius.
For all I know, there is some stock endmill with a 3" radius at least that large on a 1" shank tool but I haven't found anything.
Any help/suggestions would be appreciated. The job is 6061T6 aluminum.
The cut is very shallow.
Thanks in advance.
