Application
Operation Stability • Does the threading machine have good or bad stability?
The possibility of increasing tool life, especially when the threading process is unstable, can be expedited by
positioning and clamping the insert into the pocket of the holder. ISCAR’s recommendation for interrupted
machining, expected vibrations, etc., is to use a more rigid clamping system. For external threading,
you can use the table below, whereas for internal threading, contact an ISCAR consultant.
