S25S DDUNR boring bar — right‑hand holder for DN-- 1104 indexable inserts by Teknik Makina

The S25S DDUNR boring bar is a right‑hand turning holder engineered for use with DN-- 1104 indexable inserts, providing a precise 25 mm shank and 250 mm overall length for workshop and CNC turning tasks

• 250 mm overall length
• Right‑hand cutting orientation
• For DN-- 1104 indexable inserts

Stable clamping and consistent cutting performance

The holder is designed around a 25 mm shank and the ISO designation S25S DDUNR, which together provide secure seating in standard tool posts and a predictable centre of gravity during rotation. This translates into reduced vibration and a steadier cutting action, so machining passes are more consistent and surface finish variation is minimised. The specification also supports repeatable setups when changing between similar operations, reducing non‑productive time at the machine.

Geometry that improves chip control and tool life

With a cutting angle of 93° and a cutting height of 50 mm, the tool geometry is arranged to guide chips away from the cutting zone and to present the insert at an effective engagement angle. This positioning lowers radial loads and helps to avoid unexpected insert edge damage, enabling longer insert life and fewer interruptions for tool changes. The design is particularly advantageous where stable material removal and predictable tool behaviour are essential for productivity.

Practical dimensions for reliable workshop integration

The boring bar’s 250 mm overall length and a nominal diameter of 32 mm provide a compromise between reach and rigidity; extended reach is available without sacrificing too much stiffness. The unit weighs 0.956 kg, which aids in stable handling and mounting while keeping the assembly manageable during tool changes. Compatibility with DN-- 1104 indexable inserts makes the holder suitable for a wide range of common turning tasks where indexable tooling is preferred for economy and fast indexability.

Clear sourcing and workshop support from Metav

Acquiring tooling is simplified by a reliable supply chain: the holder is stocked and can be supplied through Metav Werkzeuge, which combines extensive range and consistent availability from a European distribution point. Technical details such as ISO designation S25S DDUNR, shank and length figures are provided to support purchasing decisions and to ensure the holder matches existing tool stations and insert families.

FAQ

Which inserts are compatible with this holder?
The S25S DDUNR boring bar is specified for DN-- 1104 indexable inserts and is configured to locate and clamp that insert family reliably.

Is the holder suitable for right‑hand turning only?
Yes, the S25S DDUNR is a right‑hand holder; the cutting orientation and geometry are optimised for right‑hand turning operations.

What are the key dimensions to check when mounting this tool?
Important measures are the 25 mm shank diameter, 250 mm overall length and the 50 mm cutting height, which should match the tool post clearance and the intended reach requirements.

How does the 93° cutting angle affect machining results?
A 93° cutting angle reduces radial loading on the insert and improves chip evacuation, which supports smoother cutting and can extend insert life under comparable cutting conditions.
