PDUN boring bar, negative, steel ( DIN 8024 )
for copy and longitudinal lathing with DN indexable insert

Application:  Ident. No. 051–076: precision-manufactured steel
For copy turning and longitudinal turning using DN boring bar with clamping surface, D type, 93° pitch
55° indexable insert angle, 55° tip angle, 0° clearance angle
Execution: Advantage:
 Ident. No. 001–046: precision-manufactured steel  very slim geometry, optimised for contour turning
boring bar, D type, 93° pitch angle, 55° tip angle, work
0° clearance angle  negative body geometry ensures good stability and
absorption of force for large cutting depths
Ident. No. 001, 011, 021, 031, 041
