S40T DDUNR Boring Bar — for DN--1506 Indexable Inserts, ø50 mm, right-hand

A S40T DDUNR boring bar engineered for right-hand cutting applications, optimised for external boring with DN--1506 indexable inserts and a compact overall length for workshop versatility

• Right-hand cutting geometry
• Compatible with DN--1506 indexable inserts
• 50 mm outer diameter, 300 mm overall length
• Shank Ø 40 mm for standard toolholders

Increased stability for reliable external boring

This boring bar delivers notable stability through its substantial diameter and balanced mass, which is especially valuable when long overhangs are required. The combination of a 50 mm outer body and a shank Ø 40 mm means that bending is reduced and vibrations are damped, so a steady cutting motion is maintained. The measured weight of 2.848 kg contributes to inertia that smooths chip formation; the result is improved surface finish and less rework, which supports higher throughput in repetitive turning tasks.

Predictable set-up and fast insert replacement

Designed around the widely used DN--1506 insert format, the tool reduces set-up variability and simplifies insert sourcing. The DN--1506 compatibility ensures that cutting edges can be replaced quickly while maintaining the same clamping position and cutting geometry. The right-hand cut and the 93° cutting angle create a chip flow that is predictable under typical turning feeds, which shortens process approval times and lowers the risk of unexpected scrap during production runs.

Clear dimensional control for fixture and toolholder planning

Key dimensions are provided to assist planning and fixturing: 300 mm overall length, 60 mm maximum cutting height and a defined shank diameter for common holders. These numerical values allow straightforward integration into existing tool setups and CNC programmes. Where tool clearance is critical, the compact overall length helps to keep the centre of gravity closer to the spindle, which is beneficial for reducing runout effects and preserving repeatability across batches.

Built for workshop reliability and compatibility

Manufactured by Teknik Makina to an ISO-style designation, the bar is intended for consistent mechanical performance and uncomplicated maintenance. The standardised interface for the DN--1506 indexable inserts and the indicated clamp holder size assist with interchangeability across similar tool families. Documentation and marking include the ISO-format designation S40T DDUNR, which helps traceability in tooling inventories and supports predictable procurement cycles.

FAQ

Which inserts fit this boring bar?
The boring bar accepts DN--1506 indexable inserts; the S40T DDUNR interface has been specified to ensure correct seating and clamping for that insert format.

Is the cutting direction right-hand or left-hand?
This tool is designed with a right-hand cutting geometry and should be used accordingly in compatible toolholders and spindle orientations.

What are the key dimensions to check before ordering?
Verify the outer diameter (50 mm), shank Ø (40 mm) and overall length (300 mm) to ensure compatibility with existing holders and to calculate overhang and rigidity for the intended operation.

How does the 93° cutting angle affect machining?
The 93° angle promotes controlled chip direction and stable cutting forces during external boring, which helps to maintain surface finish and repeatable part geometry.
