  It is not recommended to drill with cylindrical milling tools. Theoretically it is possible, but because of possible problems with chip-congestion the tool can easily break.
  
  When milling small grooves, the chip must be able to clear the groove. It is essential to start each milling process with a 'ramping' process (an X or Y movement when lowering the tool into the material). This will ensure that an angled groove will be created to reach the working depth at a point where the milling process will begin.
  
  Never plunge or drill at the beginning of the process.
  
  Milling IOL lenses at normal temperatures:
  The feed should not exceed spindle speed (RPM) divided by 1000.
  
  This results in a feed per revolution of maximum 1µm.
  For example: at 40,000 RPM the XY feed must not exceed 40 mm/min
  
  Milling IOL lenses at freezing temperatures:
  The feed should not exceed spindle speed (RPM) divided by 300.
  
  This results in a feed per revolution of maximum 3,5µm.
  
  For example: at 60,000 RPM milling at 200mm/min. is possible.
