Need to know best way to machine a chamfer READ

cool. So will it look the same if I use a 4 flute 1/2" ball mill on the ends and a 45º cutter for the sides?

No, the shape would be much different with a ball end mill because it's an arc, not a straight line like a chamfer cutter.

If you have a CNC mill, then you could use a ball end mill and profile the shape as a 3D profile and it would come out correct.
 
Ok, check this out. I got a brand new USA made 4 flute 1/2" ball nose endmill in the mail this afternoon. So I grabbed up a piece of DOM from the scrap pile and milled a 3/8" slot in it followed by the 1/2" ball mill. I can definately live with that. I should have went about .020" deeper and it would be exactly .500 wide.

Thanks y'all
