I wanted to put a groove in either side of a level I am making. Just to be able to grip it better. Not having a ball end mill on hand, I decided to try a ball end carbide burr.
Put the burr in the collet and just nipped it up to check if I had enough clearance.
Set it all up very carefully and proceeded to start the cut. The burr was cutting wonderfully, then I realised my groove was running downhill. ID10T machine operator forgot to tighten the collet properly. GRRRRRR.
