So....
Another machine not working till morning.
That's what happens when the engineer knows a bit how to operate the machines but doesn't have a grasp on how cutting tools work...
Replacing 60€ tools every 4 hours that should last a week is not profitable.
When so many tools are spent that there's no more in stock.
Also manufactor has cutting parameters for a reason... Making the tools work 3 times faster or deeper does not mean profit, means damaged machines and tools.
As comparison, think over clocking a cpu to 7000hz and pushing it to the max 24h a day...
