S32T DDUNR boring bar — 32 mm shank, 300 mm overall length (Teknik Makina)

The S32T DDUNR is a right-hand boring bar designed for internal turning operations with DN-- 1504 indexable inserts, suited to workshops and production environments requiring repeatable results

• 32 mm shank for secure clamping
• Compatible with DN-- 1504 inserts
• 300 mm overall length for deep bores

Stable clamping for vibration-free machining

A larger 32 mm shank provides increased rigidity at the toolholder interface, reducing chatter and vibration during internal cutting. The combination of a solid shank and the tool's mass helps maintain a consistent tool position, which translates into improved surface finish and repeatable bore diameters. For processes where dimensional stability is critical, the holder’s physical properties support tighter tolerances while lowering scrap rates and secondary operations.

Optimised insert fit and efficient chip flow

Designed specifically for DDUN style inserts and compatible with DN-- 1504 indexable plates, the toolhead geometry aligns insert seat and cutting edge to promote predictable chip formation. The 93° cutting angle and 55 mm cutting height assist in achieving stable engagement with the workpiece, particularly in internal bores where chip evacuation is limited. Using standardised inserts reduces downtime for tool changes and keeps inventory management straightforward for production planning.

Practical setup and workshop integration

With an overall length of 300 mm and a listed mass of 1.83 kg, the bar offers the reach required for deeper machining tasks while remaining manageable during fixturing and balancing. The designation for the clamping interface is listed as 15, enabling compatibility checks with existing tool posts and holders. The right-hand cutting orientation ensures correct cutting direction without modification to existing lathe settings, simplifying set-up and reducing trial cycles before production.

Consistent supply and application support for production

The holder is engineered for repeatable internal turning operations across a variety of steel and alloy components where indexable inserts are preferred for cost-effective edge replacement. Sourcing from an established distribution channel provides a practical advantage: Metav’s logistics and quality scrutiny in Emmerich function as a reliable supply filter for the European market, supporting continuity of production and predictable lead times.

FAQ

What inserts does this boring bar accept?
The boring bar accepts DN-- 1504 indexable inserts of the DDUN type; these inserts are the intended geometry for correct seating and chip control with the S32T DDUNR.

Is the tool suitable for deep internal bores?
Yes — the 300 mm overall length and 32 mm shank of the S32T DDUNR provide reach and rigidity appropriate for deeper internal machining tasks where indexable inserts are used.

What is the shank size and why does it matter?
Shank diameter is 32 mm; a larger shank increases rigidity, reducing vibration and improving dimensional repeatability during internal turning operations.

Which cutting direction is intended for this holder?
The design is for right-handed cutting, matching standard lathe feed directions and eliminating the need for reversal or special holder arrangements.

How heavy is the tool and how does that affect set-up?
The tool weighs 1.83 kg, offering a balance between reach and manageable handling during mounting; its mass contributes to stable cutting behaviour when properly clamped.
