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.
 

規格特點
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.
