External parting and grooving
When choosing the appropriate parting tool there are some things to keep in mind.
Depending on the material range and spindle size of the machine, tools of different styles 
should be selected with care.
From 1.0–13 mm diameter  
– CoroCut XS tools are the ideal choice as they have been made to a high degree of accuracy 
with holders and inserts all precision ground. The component tolerances, therefore, are bet-
ter maintained and the sharper inserts produce a superior cutting action. CoroCut XS hold-
ers can also be used as a stop for the bar material.
