1. Reduced batch change over time using tooling kits
Quicker tool changing 
- External turning (5 to 10 mins)
this increases when using shank tools with high pressure 
coolant.
- Internal turning (5 to 15 mins)
with boring bars it takes longer time than a shank tool with 
center height and internal coolant setting.
- Driven tool holders (5 to 20 mins)
standard driven tools are either ER collets or face milling. 
ER has a limited tool diameter allowing only end milling 
(max dia 25 with ER40). This means either low productivity 
or 2 separate driven units are needed which increases the 
setting time and investment.
