Turning tools \ ISO clamp holders for internal machining
PTFN boring bar, negative, steel
For longitudinal turning using TN indexable inserts

Application: Advantage:
For longitudinal turning using TN 60° indexable  three-edge geometry lowers costs per cut
insert  negative body geometry ensures good stability and
Execution: absorption of force for large cutting depths
 precision-manufactured steel boring bar, T type,
90° pitch angle, 60° tip angle, 0° clearance angle
