Nice finish, fits very well in my mill ISO40 taper spindle. I could not measure any runout using my 0.01mm dial indicator, but I measured 0.03mm runout on the face mill which was mounted on the 22mm arbor. I did not try to figure out if this tiny runout was caused by the arbor or the face mill. I guess the face mill. Nevertheless, the result of some test milling on steel was excellent!
