Dear #CNC#Metalwork#Lazyweb, if you had 100 aluminium enclosures with 1.6mm thick end-plates that you'd planned to mill some openings into (1x rectangular, 6x round) but you've discovered that the alloy is some part-aluminium-part-cowdung rubbish that stretches rather than cuts (even drilling a hole with a twist drill is a horrible experience), what could you do. 4-flute endmills don't even cut, they just bulge the metal. A 4mm 1f endmill is the least awful (so far).
