S50U DDWNR Boring Bar — DDWNR for DN-- 1506 indexable inserts (Teknik Makina)

A sturdy S50U DDWNR boring bar engineered for internal turning operations, compatible with DN-- 1506 indexable inserts and optimised for right-hand cutting.

• S50U DDWNR ISO design for secure insert clamping
• Compatible with DN-- 1506 indexable inserts
• 50 mm shank diameter for stable machining
• 350 mm overall length for deep bores

Precision and stability for internal boring

The S50U DDWNR holder combines a rigid 50 mm shank with a long, 350 mm profile to reduce vibration during internal turning. That rigidity translates into a more consistent cutting line and improved surface finish when working in confined bores. The relatively high cutting angle of 62.5° helps to distribute cutting forces, which reduces chatter risk and extends insert life. For machine shops requiring predictable repeatability, this design offers a practical way to increase process stability without changing machine setup.

Compatibility, insert handling and machining efficiency

Designed for DN-- 1506 indexable inserts, this DDWNR-style holder supports efficient insert changes and secure clamping for stable cuts. The right-hand cutting orientation and the ISO-style configuration mean the tool fits common turret and toolpost arrangements without modification. Explaining technical terms: an indexable insert is a replaceable cutting tip, so only the tip is renewed when worn, reducing toolholding costs and downtime. The combination of 350 mm overall length and appropriate insert geometry enables access to deeper bores while maintaining control over chip formation and heat at the cutting edge.

Durability, workshop integration and practical benefits

At a weight of 5.298 kg, the assembly signals a robust construction suited to industrial usage where tool stability matters. The nominal 63 mm body diameter around the cutting zone helps maintain alignment under load, which supports repeatable tolerances in batch production. For engineering teams, the primary benefits are reduced rework and longer intervals between tool changes; for maintenance staff, the ISO-style holder simplifies inventory, since the same DN-- 1506 inserts can be stocked for multiple tool types. Overall, the design is intended to integrate smoothly into existing turning workflows while improving process reliability.
