For those engaged in high-mix, low-volume machining, versatility (mostly) rules
Aluminum one day, titanium the next, low-carbon steel the day after that. When you have no idea what’s coming down the pike, it's obvious that you need cutting tools able to survive whatever you throw their way. But is survival enough? Is it better to sacrifice some modicum of performance to avoid switching to a material-specific cutting tool, or to keep the tool crib inventory to the bare minimum by going to a more general-purpose grade of carbide and tool geometry?
