Ok, so I just broke a tap in a blind hole. Before tapping the hole was blown clean and greased up afterwards, tap did not look worn. Just bad luck.
What's the best common practice? I am considering logging how many holes I tap and then throw the tap away at a given number of cycles irrespective of its apparent condition. It was a "high end" Carmon M6 tap (chips up).
If I reduce the feed drastically, would it work to drill it out with the 5.1mm TC carbide drill ot will I just break the drillbit? I see that milling is recommended, but that means a bit of work setting up and programming. I'd rather break a small drill than a more expensive end mill.
Thanks. Still a rookie on my second year of CNC machining..
