S50U DDUNR Boring bar – Right-hand, for DN--1506 indexable inserts (Teknik Makina)

A S50U DDUNR boring bar designed for precision internal machining with right-hand cutting and a 350 mm overall length.

• Right-hand boring bar, 93° cutting angle
• 50 mm shaft diameter for stable clamping
• Compatible with DN--1506 indexable inserts
• Total length 350 mm, solid construction

Stability and accuracy for repeatable internal bores

The solid design and substantial mass provide vibration damping that supports precise boring operations. With a 50 mm shaft and a body diameter of 63 mm, the tool resists deflection under load, which reduces bore runout and improves surface finish. The 93° cutting angle positions the insert for effective metal removal while maintaining bore geometry. Use of standard indexable inserts simplifies replenishment and ensures consistent cutting performance across production runs.

Higher uptime through predictable wear and quick insert changes

Equipped for indexable tooling, the concept focuses on efficiency: insert changes are swift and economical, leading to shorter downtimes and steady cycle times. The 65 mm cutting height allows robust engagement with the workpiece while preserving insert life through favourable cutting geometry. Right-hand cutting direction supports conventional lathe setups and predictable chip evacuation, contributing to reliable throughput and cost-effective tool management in series production.

Ease of set-up and workshop integration

The 350 mm overall length and the ISO-style designation make integration into existing toolholders straightforward. The tool is identified by its ISO code S50U DDUNR, which helps matching with holders and clamping systems; the specified clamping holder designation is 15, aiding quick procurement of the correct fixture. At 5.153 kg the assembly delivers stabilising mass for medium-duty internal turning tasks without requiring special balancing, while compatibility with DN--1506 inserts standardises spare-part stocking for maintenance teams.
