Hello,
I have unfortunately done some damage to the mini CNC machine this afternoon: the drill went into the CNC bed. The bit I was using was T23, which would probably need to be changed. @Federico already replaced it with a new one. The CNC is still usable.
I am happy to cover the cost necessary to restore the machine to the initial state.
Sorry for messing this up, should have been more thorough in measuring the thickness of my wood.
Here is a photo of the damage done to the bed:
