Profile milling ASTM A514 using a Mitsubishi 2.5" button cutter with VP15 JS chipbreaker at 2200 rpm and 165 ipm. Axial cut 1/4", radial .1 to .2. The endmill was a 1" x 4" loc regrind from Mountain Top Sharpening. Paramaters were 2.05 axial, .025 radial at 2200 rpm and 88 ipm. The endmill was taken from the "needs resharpening box" and was quite dull. Cutter life was excellent for both.
