I have been using 4 flute drill/mills but now that I am moving this job from my Kitamura to my new Brother I need one that is free-er cutting. This has been on my list for years but I have not found what I need and want to make sure it doesn't exist before getting a custom tool made. I use this tool to profile the ends to length on 1/4"x1" 6061 bars then chamfer the ends to fit a dovetail on mating parts, as can be seen in the photo. The chamfer is .155" long, hypotenuse, or .09" rise and projection. I really want the chamfer on the end mill to be helical ground vs flat. An endmill then chamfer tool will not work as I need a clean transition from the chamfer to the vertical wall that the chamfer ends at. I do enough of these parts a year and will be doing them as long as I want that price isn't much of a concern for the right tool.
